Review: Streamlight - Wedge flashlight

Sharpie for Scale
I'd been without an EDC flashlight since loaning mine to Tactical Baby for school camp, never to be heard of again. (the light, not the TB, she had a blast). I made do with a petrol-station bargain bin LED light that was usually functional but not especially bright or reliable. So when an opportunity came up to  try out another I jumped at it. I had never heard of Streamlight or their Wedge light but as soon as I looked it up I knew it was the next light or me.
 
I liked the look of its sleek but robust design, bulkier than a pen-light and that it looked like it was designed for both pocket and PALS/MOLLE carriage. I have a Fellhoelter bolt-action pen light on my Hazard 4 chest harness (which is pretty much my principle EDC go-to), but its not much more than a "dropped my keys" or pupil-dilation checking tool. 

The Wedge has a pleasant solid heft to it at 4oz (113.4g) and it fits the hand nicely, with the finger groves fall naturally into index and pointer fingers, placing the wheel button squarely under the thumb. The heel of the palm seats the butt-end of the light, tucked in securely by the pinkie finger. It measures 5 4/5"X 2/5"X ~1" (13.87 x 1.52 x 2.54 cm) overall, ( not counting the subtle pen clip ( which is reversible for lefties or righties). I tend to wear it in my front right pants pocket with the short paracord loop easily hookable for easy access. A month of daily carry has worn the anodizing of the tip, to zero functional effect.

candle Mode 
The light is activated by rolling the wheel button forward to the stable mid point, producing a bright, clear white light rated at  300 Lumen. This is the Constant-On Mode, which has a 3 hour runtime. When engaged, a small green LED behind the wheel is illuminated. This seems redundant as the main emitter LED is very clear. My own testing has the battery life lasting over 4 hours but 3 hours is a safe benchmark.  The green LED shifts to red when battery life is low, which is a nice feature. Even after my 4 hour test it wasn't especially hot either which was nice, the heat-sink of the all metal body works well. 


Standard mode activate

The built-in Lithium Polymer batteries are charged via a recessed, waterproofed USB-C port in the butt of the Wedge. When charging, the behind-the-wheel LED is red until full charge at which point the indicator light goes green.

But this is where the extra distance on the wheel button comes in. If you push the wheel beyond the constant-on mid-point, you activate the THRO, (Temporarily Heightened Regulated Output) mode. This kicks the constant-on 300 Lumen up to a dazzling 1000 Lumen output. Light throw is rated at 225' (69m) at constant-on and 360' (110m) in THRO mode. One thing that impressed me was the wide cone of light, with the main cone being around 120 degrees wide, with a secondary cone at around 160 degrees. This extra wide beam provides for an almost full room coverage from a doorway, which is very handy for those "bump in the night" investigations or "where did that battery roll under the bed" searches.

The constant-on setting is standard, with the THRO mode requiring constant forwards pressure to maintain it, such that an initial push forwards may move directly to THRO-mode then back to constant-on. This isn't too much of an issue, but I did find that some finesse was required to switch it on without moving to THRO-mode, or flickering ON/OFF. That can be a little annoying, specifically because when I want light, I want constant, stable light NOW. 


THRO mode active: wider, brighter, longer
Another thing I like about this light is its slim but not skinny-size making it convenient to deploy in a pocket, on a belt or even in the channels of PALS/MOLLE. Perfect for placement on a chest-rig or on a pouch. It's a snug fit, especially on a rigid surface, but that adds to the security of it's carry. The para-cord fob allows for easy draw, and just like that you have the utility of a bright sharp white light at the slide of a thumb.

The base of the light, even with its recessed USB-C charging port and pen clip sits flat nicely allowing the Wedge to be stood up in "candle mode" and given it's wide arc, it will illuminate a whole tent, room or goodly sized cave. 

MOLLE carry
The lens glass is slightly inset from the rim of the frame, offering it some measure of protection against  scratches and impacts. Whilst I wouldn't recommend using it as such  I suppose one could grip it like a kubaton for self defense purposes. Every tool is a weapon if your imagination can stretch far enough. It's not going to do you as a set of brass knuckles, but if you ice-pick your grip you'll make a bit of a impact focus point, even if you have to drive the switch with your pinky. Good for temple-indexing, OK for cool. 





ergonomics
I really like how the light indexes in my hand, how easy it is to activate and the sheer volume of the light it emits. It is certainly one of the most powerful lights (especially for its size) that I've had. Its sleek form factor makes it unobtrusive and easy carry and quick to deploy. My only complaint would be that the thumb switch slips back from ON to OFF too easily, if its not seated quite right. This may "wear-in" over time, and hopefully in the right direction, but isn't enough to put me off this light. I've subsequently found that flicking it to "ON" then getting my thumb of the dial reduces this stutter effect, so i'm willing to concede some user error may be in play here

One last thing, if you ever felt the need to illuminate your brain, the emitter end will fit up the standard adult nostril and will light your honker up like Rudolph. Tastes like Crayons too.

Review: Sailors Compass - Oceanus Brass

I've covered compasses before, mostly as a generic " have a compass, navigation is important" tool and as part of a variety of multi-tool items or kits that include a compass but this one is a little different. I backed a kickstarter for a boutique compass with maritime style. Oceanus Brass specialize in nautically inspired items milled in brass. This is the Oceanus Brass - Sailors compass. Which I backed on Kickstarter. They're in full production now, so you can pick one up, or anything else in their range. Their latest Kickstarter is for a plastic bottle cord maker and looks great too
Brass is an excellent material for traditional nautical kit for several reasons: It is hard wearing to withstand long periods between resupply or repair options. Corrosion resistant to resist saltwater exposure. Non-sparking to keep powder and timbers safe and non ferro-magnetic so as not to throw off your compass needle. It also has a pleasing heft and a bright luster. 
The sailors compass comes as an un-embellished and unadorned puck, with a seam line running its circumference at the 2/3 of its height. The seam line is narrow when the lid is secured and both top and bottom edge of the puck are evenly beveled and smooth. The "lid" unscrews for two full rotations  along finely machined threads, with just index and fore finger and thumb vs palm needed to open it.
Inside the compass is a liquid filled needle chamber, with a well defined needle including a nicely pointed "head" featuring a glow in the dark "dot" for night-time navigation. The tail end flight is subtle and balances the needle both physically and aesthetically.
 
The bezel is gently notched for easy grip and rotates smoothly and features degree markings, in 20 degree major spacings, with minor marks for 10 degrees and 2 degrees. It's firm enough that it won't slide of its own accord but smooth enough that it will turn with a finger-tip's pressure. The backing of the bezel is a ring of glow in the dark material to provide a readable back lit bearing in the dark. A fixed red line serves as the index mark and a pair of embedded glow-dots in the base of the bezel chamber lines up with the North indicator. A central dot completes the after-dark navigation picture. 

The compass is moderately large for an EDC pocket compass, at 2" (55mm) in diameter, 5/8" (17mm) in height and 6.8 oz (194g) in weight, but its smooth and solid design makes it an easy carry. Whilst it would not take the place of a good lensatic compass for navigation. It certainly does the job for simple wayfinding navigation. 




 Solid brass construction provides sea-worthy durability. The Sailor's Compass can be dropped, frozen, banged, forgotten until it isn't. If i had to pick something I didn't like about the compass it would be that it's too smooth. The unadorned surface might lead to slick, fumbly fingers to drop a vital piece of kit and some knurling or a dummy-cord knob or thread-hole might go a long way to securing it. All told though, it makes for a very pleasant EDC pocket addition.

Review: Tactica Talon

Here's a thing. How often do you find yourself in need of a tool for a quick fix? A loose screw, a non-twist bottle, a package to open. Often, the tool you need is buried in a drawer or lost in the tool shed, turning a 20 second job into 5-10 minutes. Or worse, you find yourself in a tricky tool situation away from home. Even the most efficient bug out bag or EDC can be a pain to rummage through. There's only so much you can load your cargo kilt up with before you get the jingle-shakes or worse, slippage. One solution to this is to combine multiple tools in to one lightweight system.

One such system is the Tactica M100 Talon. It certainly qualifies a "the tool you keep with you". It's lightweight, compact, versatile and might just be your new best prepping lifestyle friend. Whether it's mountain biking, snowboarding or just around the house, the Tactica Talon has got your back. Right there in your back pocket.

The Talon is designed and made in Melbourne. My home town so it was especially exciting or me to back and support the Kickstarter for it. So, here's what it is. Primarily a Hex bit driver, with a climbing carbiner form factor. At its core a hardened stainless steel frame wrapped in a pocket tech friendly lightweight composite material that won't scratch your valuable iDevices as well as being 40% lighter than titanium.

Inside the body of the composite component is a space for two 1/4" hex drivers retained by a removable silicone rubber slot-plug (Phillips + flat head included). The narrow-eye of the tool is cut to act as a multi-wrench with two versions being Imperial - 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16in or the Metric - 5, 6.25, 8, 10, 11, 13, 14mm versions. Both versions have a 1/4" Hex socket built into the body as a heavy duty driver. The "mouth" of the storage slot is the primary hex driver, and is fitted with magnetic tool retainer in its side to assist with that.

The big end of the "wide-eye" of the carabiner is also fitted with a bottle opener. A raised notch on the "back" of the tool acts as a snag free, TSA safe Package Opener. ( ha, so they say. )

Inside the lip of the wrench holes are rulers, on either side, metric on one and imperial on the other. They are only small so you wont be checking fish-size or the like but perfect for sizing hardware like drill bits and bolts up. Beside the bottle opener in the "eye" is a hole drilled for a key chain split-ring. keeping it out of the way for using the wrench.
I don't think I'd use this at all as this isn't a tool I would put on a keychain, but it certainly could work for that. One thing I did like about its design is the view-port cut through the side which shows you if a hex- bit is inside. not quite big enough to see what kind of head, but certainly a sanity check to see if its one or two tools stored with a quick back and forth rattle check.

The slot-plug has two friction lugs to hold it in place but is fully removable, which makes the whole assembly easier to put together and reduces the chance of it tearing after repeated use but the fat that it could become detached and lost and the stored hexbits along with it is a small worry. The slot-plug is tight fitting and I have no such worry of it coming loose by accident.

My biggest gripe was the out-of-the-box realization that it shared the "form factor" of a Carabiner, it was in fact NOT set up to clip open. Few moving parts means simpler manufacturing and a stronger overall design.it would be convenient if it would auto-clip to bags, packs and pants, but it is narrow enough that it can be clipped to an existing carabiner and hung ready for use. Measuring in at 80mm x 40mm x 12mm (3.154"x1.57"x0.47") and weighing in at a slight 45g (1.6 oz).

Given its composite encapsulation and lack of any sharp or rough edges, it makes an excellent pocket carry. Ready when you need it and not wearing holes or scratching screens.


The angle of the primary hex driver lends itself to the Talon siting nicely in the palm of the hand though the short hex-bits can leave the access to whatever is being driven to be quite tight. It's certainly not a tool for hard and everyday use, get full sized driver for that. This is a tool for small jobs and "I just need to fix this one thing" jobs. It will however, put together an Ikea Billy bookshelf up like no-ones business.

Go further and do more than single flat or a Phillips head will do but the great minds at Tactica came up with this; a12 Bit Toolpack giving you a great selection of hex bits to use. They have chosen a solid cross selection of bits that would cover most circumstances whether it's at home, work or on your next adventure. The Toolpack contains the following hex bits: Phillips #0, #1, #2 Flathead #3, #4, #5 Allen key sizes 3mm, 4mm, 5mm and most excitedly Torx T10, T15, T25. The full set weighs only 80g (2.8 oz) a small price to pay for the added utility of having the right head to hand.

The collection of bits are titanium coated (for longer wear protection) and ruggedly ground, for greater fortitude. Comparing the included bits with those of the MiniInch tool pen systems and they are stubbier and more ruggedly produced than the grey MiniInch bits but otherwise fully compatible, other than being unable to store two in the Talon's internal storage due to length.

There have been reports that the box opener tool blunts after limited use, but given it is a spire of plastic, I'm neither surprised nor concerned. My only other gripe with it is the lack of an integral clipping mechanism as previously mentioned. And the wide turning circle of the main hex driver which is a bit tricky in tight spots.

Review: L10 flashlight

I love flashlights and always like having extras on hand, following the "two is one and one is none" philosophy. pocket and palm sized lights are even better, as they can fit into small packages, and be used in variety of settings. I especially like small lights that I can throw, drop behind a bookshelf or wedge into a crack to illuminate a workspace. I have a collection of these as part of my EDC, including the previously covered bullet-02-smallest-edc Lumintop Tool AAA Jenyx UV and an as-yet unreviewed Four Sevens Bolt action penlight

This particular addition is the L10 Twisty from L3-Illumination Lumintop. It is a lightweight(at just 20g (0.7oz) without battery flashlight, featuring a Cree XP-G2 9R5) LED with lifespan of 50,000 hours and it takes a single 1.5V AA battery (ni-mh, alkaline). It's reported that rechargable high-performance 14500 batteries are not recommended because they heat up quickly.

Constructed from durable aircraft-grade aluminum with a Type III hard-anodized anti-abrasive finish to house the toughened double ultra-clear glass lens it is waterproofed to IPX-8 Standard. It measures just 79mm(length)x17.1mm(dia) for a very convenient pocket addition. I have mine attached via the end-cap lanyard hole to a short cord and thus attached to a house-key. Ease of entry for those dark night returns.

The L10 is activated by a twist switch set into the body of the light around the 2/5 mark of the body. Twisting the head of the L10 engages the first of four modes of action. The four modes activated by turn and re-return the head of output are as follows: Firefly (0.09lumens brightness with 147 hours duration); Low (3 lumens, 30hrs ); Medium (30 lumens); High (120 lumens, 1.5hrs duration) (when tested with Ni-mh battery with actual capacity 2500mAh).

It features a stable current regulated circuit, providing stable brightness throughout use. Unlike many flashlights of this type, it has no mode memory, always starts on lowest mode. Just tighten and loosen the head to switch between modes. Its flat base, and lanyard cutaways allows the light to be placed on its end to move into its practical candle mode.

The head end comes right off by unscrewing to replace the battery which is something you need to bear in mind when switching modes and also using the light in wet situations. It has a rubber- o-ring to seal it but once over-unscrewed the head can just fall right off, exposing your internals, dropping your battery and shutting of the light all in one annoying "ker-plunk".

All in all the L10 makes a very useful little light, great for those "i dropped my "X"-in the foot-well of the car", "where's the damn key-hole" and "what's under the couch?" moments in which a larger more powerful light would be overkill. Solidly made, functional and convenient, the L10 is welcome addition to my janitor-grade bundle of keys.

review - Kogalla battery



I'm a fan of my electrical gadgets, and with that comes the need to keep them charged on the go. whether it be in transit, on the trail, out cutting wood or doing chores, I like to listen to my tunes, stay in touch with the news and my feeds and all of that takes electron juice. 

I have a collection of batteries, from simple vending machine ones to those that came as bonus to some of my solar chargers like the Kogalla solar bank I recently covered.

I've covered some of my battery collection as well in the Limefuel by Limeaid . 
But, this new one is very nice. The  Kogalla BatPak 2 is a rugged, rechargable storage bank. Designed specifically to power the Kogalla RA Adventure Light, it also does a great job charging phones.

Built with  a whopping 48,580 mWh charged by a 5V, 2.1A Micro USB port. Outputs are by 3 5V 2A USB ports. which can be run simultaneously, for a 3.7V/13,400mAh capacity


Compared to the vending -machine issued Promate charger ,with only 10,000mAh with a 5V 1A and 2A dual outputs. The power dense Kogalla BatPak 2 is wallet sized and fits nicely in a pocket.


With its triplicated power outputs, and compact size, the BatPak 2 is a remarkably portable and powerful tool to keep your gadgets and devices charged on the go.
The protective case is simple and simple, with a single texture and  few extrusions, high- speed, low drag indeed!

I keep it charged up and couple it with a rugged Lightning cable to keep my iPhone charged. It usually sits in a side pouch of , my EDC pack the Mystery Ranch 1DAP but it just as easily sits in cargo pocket of pants or tucked away in my Hazard4 Escape RG harness.

Review: Kogalla solar bank

I love my portable batteries. mostly because I love my power-hungry iDevices and not only go to a lot of long meetings, but also occasionally camping trips and other away-from-the wall outings! Having portable power not only extends my mobile browsing and picture snapping abilities, but also makes me a hero when someone else is trying the same and didn't think to prepare.

However, even battery packs like the hefty Limefuel Limeade with its 18000mah
are only as good as their capacity. Once dry, they're done, which is why I am also really keen on alternate power sources , especially in the event of a long term power outage. My favorite power source is solar, being free, non polluting and very sustainable.

I also love it when two great flavours like this mix, such as in the Kogalla solar storage bank. The SSB2210 Solar Storage Bank is a high-energy, ultra-slim power bank matched to a high-efficiency foldable solar panel housed in rugged, waterproof fabric body.

Unfolding exposes four solar panels each roughly the size of the iPad Air 22cm (8")x 13cm (5") x 3.5cm (1 1/4") compared to (24 cm (9.4") (h) 16.5 cm (6.67") (w) 7.5 cm (0.30") (d)) and when fully unfolded it stretches out to an overall 61cm (24") when fully deployed the SSB2210 offers a huge 22 W capture capacity s worth of panels which allows for fast charging times in full sunlight.  Matching the panels to the power bank allows for energy harvesting even in low-sun conditions. 920g (2lbs) n not bad at all, considering both the panels AND battery in one.

Not unfolding the panels limits the capacity but reduces the footprint required. given that the four panels fold nicely and will constantia a bit to allow it to stand up whilst exposing more panels to the sun. This is also important when it comes to getting a good angle to the sun.

Maximum possible solar generation at your location is possible by angling the panels to the angle of the latitude at which you are located. In Melbourne, that would be 38°. You would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun. 
The general rule of thumb is that panels angled at the latitude angle, plus 15°, is best to maximise winter sun exposure. Obviously placing the panel in the line of the sunlight is the other part of this equation. Direct sunlight is best but even dappled or overcast  sunlight will generate power, slowly trickle changing the on-board battery. 

The 10,000 mAh power bank provides long battery life between charges. The power bank can also be charged through a micro-USB power input for charging during no-sun conditions. from a wall socket tor other alternate power source like

Dual high-current USB power ports (up to 12 W) lets you power lights, accessories, or fast-charge devices. The unit folds into a compact, ultra-portable kit that includes a zippered pouch for accessories. The kit also includes a flexible-neck USB light, micro-USB cable, and lightning cable. For the charging of all kinds of devices. I especially like charging my USB chargeable flashlights and phone in a modern "make hay whilst the sun shines" situation. I also charge up my other batteries for the same reasons.

I've found that I can charge either an iPad or an iPhone but not both simultaneously, now, doing some research i find that the  An iPhone charger delivers 5 Watts (5 volts at 1000 mA) and the Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA). so its not unreasonable to see that 5W + 10W is more than the 12 W output of the  SSB2210. Bearing that in mind, just like the Apollo 13 Mission Control team, do the math and know how much draw your gear is going to make on your batteries. Matching the panels to the power bank allows for energy harvesting even in low-sun conditions, but they can only do so much. Luckily I also have a dedicated iPhone solar charger...

Another neat feature of the SSB2210 is the fabric eyelets sewn into the middle of the unit and the four corners. These loops allow the solar panels to be lashed down into optimum position or onto something either for stability or portability. I lashed it to the side of my rain-fly one day, and also to the back of my hiking pack, such that my daylight hike would serve double duty of also charging batteries on the bounce.

I used four mounting points to fix it to my pack here, but left the bottom panels free-hanging.
 I knew I would need to be mindful of the panels when I shucked my pack, but it wasn't any drama at all on an hour long hike.

I generally keep this unit folded up and in the hydration bladder pocket of my day to day pack, ready to charge up my devices on the go, or to pull out and make myself a hero during long meetings.

 I can highly recommend it, especially as an off-grid power source in a sunny environment to keep your vital gadgets alive. I would couple it with other power generation and storage items such as the Beacon or the like. Diversify and empower yourself!

Review: Lumintop Tool AAA flashlight

I've been very remiss about this one, this little light has alternated between sitting in the bottom of a couple of bags, and then pockets of both pants and jackets. This is both to its credit and a flaw, but I'll get to that.

The Lumintop Tool AAA is a very diminutive light, at just over 8cm (3.2") long, and around 30g (1oz) it really is pocket sized. Taking a single AAA battery, the machined aluminium body is less wide than a single AA battery.

A single tail cap button at the rear enables the user to cycle between the three light modes with momentary toggling, which starts at a Medium of 32 lumens, then to a 5 lumen Low setting and ramping up to a 110 lumen High setting. I really like this pattern, with a medium setting to get you out of the dark, a low setting next to enable you to do your dark-work without disrupting your night vision or drawing unwanted attention at the Watergate Hotel.

Having the High setting last means that you have to call it up and not only reserve battery power, but also maintain control over the amount of light you throw, till you need it.

Another excellent feature is that once the tail cap switch is "on", the head is on swivel, allowing twist-driven switching between the three modes and "off". There are o-rings sealing the unit at both the head end and tail-cap end, either of which can be used to replace the battery.

My favourite aspect though is that the detachable two-way clip, which enables you to fix the light directly to a cap-brim, giving you a keychain sized head-lamp at a moments notice. You won't be using it to chase alligators in the sewers, but find yourself with full hands in the rain and having dropped that screw from your widget, and you have yourself a good-to-go tool for the job. It's low weight makes it ideal for this use.

It's tiny size means it gets lost easily, especially if you have a lot of loose gear rattling about. AAA's are not high-power, or long lasting, but for occasional utility use, they'll do. Threading a lanyard through either of the lanyard loops in the tail-cap, or clipping it to a keyring would probably go a long way to retaining it.

It's not a searchlight, it's not a weapon-light, its a pocket sized keychain light with a very light profile

Review: First Tatical - Medium Duty Light


I did a "quickie-review" of the First Tactical - Medium Duty Light, which arrived in the mail a few moths ago, and was seen on Breach-Bang-Clear then, but I wanted to give it a bit more thorough a review, because it's come to be a reliable go-to light here in the bunker.

This is the aptly-named Medium Duty Light by First Tactical.

I usually use flashlights that are rechargeable directly, like my now defunct  HEXBright.

Sometime though, you just want some stock-standard batteries pulled out of old TV remotes, drumming bunnies or personal upper-thigh massagers. AA's are everywhere, and the MDL takes them.

Review: Para TPS Pulley systems

I love paracord. I love titanium, I love pulleys, I love Kickstarter so when a titanium paracord pulley came up on Kickstarter, I knew I had to get on board. I've covered a titanium paracord pulley system before, in the Ti2 PB-9 Parabener systems which live on my daypack, just in case. However, they are pretty chunky, being loaded with other features, and might be overkill when all you need is some lifting and shifting.

That's where there the TPS system comes in. A bare bones pulley system, it's a Universal Pulley System made from grade 5 titanium and ready to be used for making work easier and putting no matter what you're doing. Designed for paracord, or any other 4mm line of your choosing.

The TPS pulley systems are available in four formats, the TPS-2, TPS-3, TPS-4 and TPS-5. the number value corresponds to the number of "sheaves" which are the wheels inside the pulleys, designed and produced by Andrew of Root Designs R&D .

Root Designs spent a lot of time determining the design and materials they wanted to use in these pulleys. The side plates and pins are made of Grade 5 titanium (Ti-6Al-4V) because of its strength and corrosion resistance. The sheaves are made of a homopolymer acetal (which is a very strong plastic that is used for bearings because of its low friction coefficient, perfect as sheaves). The clip-in retaining rings are made of stainless (304SS made by Smalley).

Some serious design and research went into the development of these. Based on using paracord with a minimum breaking strength between 250-340 kg (650-750lbs) for Type III to IV paracords, a FOS of 3 puts the maximum breaking strength (MBS) of the pulleys around 2250lbs. These values were tested on a computer using failure-and-finite-element-analysis software. Bearing in mind that most civilian paracord is type II to III, with minimum breaking strengths of 180-250kg, (550-650lbs). Doing these studies are part of why Root Designs needed support from crowdfunding.

Having gone through rounds of testing and prototyping, they have pulley systems now rated for a Working Load Limit (WLL) of 68kg (150lbs) and a Tested Breaking Strength of over 900kg (2,000lbs). What does that mean? it means the TPS is recommended for loads of around 68kg, and is known to catastrophically fail at 900kg. Given type III paracord will take at least 250kg, my money is on the TPS working long after the paracord snaps, if you're looking at points of failure.

What's the big deal with pulley's in the first place? Mechanical advantage! Anything you need to move or lift, these pulleys can offer up to a 5:1 mechanical advantage with paired TPS-5's. By setting them up in sequence, and threading paracord through the sheaves correctly, the power of simple machines can reduce the effort needed by up to 1/5th of the force needed by a single loop alone. A single pair of pulleys halves the effort, three, a third and so on.

I backed for and received a twin set of TPS-5's and also got a TPS-2 as well. They can be used in a variety of combinations, or singly depending on your situation and need. One thing to remember that with all pulley systems, your ability to lift is only as good as your weakest component. Any attachment accessories (I've used two steel S-hooks from Ikea, so useful) as well as Type 3 paracord. However you also need to take into account the features of the load, and it's ability to haul itself, as well as whatever you are mounting your load too.

The other aspect to be aware of is the length of cord used. For every sheave used, the length of "fall" between the sheaves increases. This needs to be taken into account when reeving (lacing) the pulleys.

Pulley systems mean that someone with little hands and arms, like Tactical baby, can lift this 2.5L kettle full of water, and hold it, in her non-dominant hand, and nonchalantly pose for photos before bedtime.

Here's a tidbit of information from the Royal Canadian Sea Cadets Seamanship manual,
Parts of the Tackle:
a. Standing Block: The block that is anchored and is not moving. This block changes the direction of the running part.
b. Moving Block: The moving block is attached to the moving end of the rope (the end the cargo is on).
c. Fall: The fall is the rope that is rove through the block.
d. Standing Part: The standing part does not move. It needs to be secured to either the standing block or some other fixed position.
e. Hauling Part: The hauling part is the part that is pulled.

But acting as mechanical advantage gaining simple machines aren't all the TPS can be used for, you can combine these little workhorses to get other tasks done too. If you need to send some gear across a ravine, creek or river, or between abandoned buildings in a desolate wasteland, each pulley was designed so it could be used as a zip line shuttle. Setting up a static line and fitting one of the TPS's on it, with either one, two or three sheaves to spread the load over the line means you have a very stable and secure system for shuttling loads back and forth.


You could even use the spare sheaves to run pilot lines to haul back and forth, as well as for suspending your load. In other applications, you could even make a dog run, or other off-ground tethering system for pets or small people whilst out and about.

I even found that by setting the TPS-5 up in a cross-woven pattern, I could make a friction belaying zip-line, in the style of the mechanical decent RACK devices offered by Petzl


Being made from titanium, acetal polymer and stainless steel, they work great in harsh environments such as the ocean, or gritty, hot environments. They could just as easily be used on a fishing boat as in the bush. The limits to their application is really up to your imagination, and material strengths you have to work around.


One of the really nice design features is their small profiles. By using clipping retaining rings, the side profile of the pulleys stay small. The TPS-2 is5/8" x 1-1/2" x 9/16". The TPS-5 is 2-1/2" x 1-1/2" x 9/16".

Basically pocket sized, no matter how you put it. The pins do not stick out from the side plate as much as a nut or the head of a bolt would, which means they are far less likely to snag or catch, as well as reducing weight The TPS-5 weighs 45g (1.6oz) and the TPS-2 a mere 18g (0.6oz). Each pulley can be user-serviced if needed using common tools, and spare parts are available from Root Designs on their website. They also offer a snap-bolt which can be fitted in place of the machined pin, around the existing sheave, to offer a built-in attachment point in the place of any of the existing pins. This is an awesome addition to have designed in, and I'm kicking myself that I didn't put in for some with my pledge. However, there's nothing magic in the bolts, and it is just a matter of finding a bolt which fits, and somewhere to shackle your pulley!

 This is the kind of gadget that you probably wouldn't think to pack in your bug-out-bag on first pass, but to kit out a minimalistic problem solving swag, you could do a lot worse than including a set of TPS's to give you an advantage over your environment!
