ORWM – CTOMS Haul System

Thursday, January 12th, 2017

CTOMS just received their prototype double Prodigy pulleys and set them up as a Haul System to demonstrate their potential.

Progress capture can be either Prussick or QA. The QA is more efficient, but they wanted to offer the versatility. Eventually, CTOMS will formalize the setup and give it a name when they offer it as a product.


Tuesday, January 10th, 2017

While most companies start out by offering commercial colored mountaineering and then add earthtones for tactical customers, CTOMS has done the opposite. Founded by Canadian SAR Tech Chris Kopp, CTOMS had tactical colored kit from the outset and has just started to introduce Orange versions of their TRACE systems for Search and Rescue work.

These two Green kits are identical except for the SOF and SAR colorways.

They have an ever expanding lone of Orange offerings, to supplement their existing line of Matte Grey and Olive Drab. Interestingly, they’ve also introduced Blue carabiners for the rope end of any devices.

They are also introducing Orange pouches for the kits.

High Angle Solutions – CTOMS – K3 Tether

CTOMS K3-Sling Alternative Configuration

K3 Tether

Sometimes the simple products are more complex than you think. Retention lanyards are an example. CTOMS performed testing on a typical helicopter retention lanyard (brand name withheld though many brands have very similar design and construction) – the type made of 1” tubular nylon with shock cord inserted into the core. The intent of the shock cord is to slightly shorten the tether to manage its length but provide stretch to a longer length for functional range.

Fall Factor 2.0: 13.2kN (2967.5 lbf) Failed

At the same time CTOMS tested their K2-Sling adjustable retention lanyard. It is a basic design of 8mm accessory cord with sewn terminations, a connector at each end, and a 6mm sewn loop attached to the 8mm with a 4 wrap Prusik. That loop is then Cat’s Paw’d onto a quick release marine shackle. The design allows for tether length adjustment and also release from the system under load in a two part disconnect that prevent inadvertent release of a sole marine shackle attachment.

A high peak force, but at least still retained.

K2 and K3 in use

The next generation retention lanyard incorporates TRACE Systems force limiting technology. The new K3 Tether is made of 6mm TRACE Systems Rope and incorporates a Quickie Ascender (QA) for length adjustment. The long leg is 2 meters long, which means at maximum reach for most people, there will still be adequate slack to allow slippage through the device to arrest a fall. The K3 has been designed for both helicopter retention and mountaineering retention. It can be configured so that the adjustment (QA) is at the harness (usually helicopter) or at the anchor end (usually mountaineering).

The lanyard has a long leg and a short leg. The long leg is for personal retention and connection to an anchor, and when mountaineering, the short leg is to connect the rappel device to. The large loop would normally be girth hitched to the harness. When climbing with TRACE Systems, the short leg also is where the belay device would be connected providing a slight extension, which is ideal in that unique circumstance. A set of ettriers can also be hung on the tether carabiner and either as a single or a pair, is an excellent adjustable daisy chain for aid climbing.

In helicopter retention mode, the K3 would normally be flipped, connecting the adjustment end (QA) to your harness, and the “Y” end loop and short leg to a connector then to the aircraft. This ensures adjustment is always in reach.

The best part of the K3 is the soft catch of a major fall and slippage of rope through the device of under 1 meter. While the test videos are not in actual tether configuration, the adaptation is practically seamless.

Drop tests on actual tethers are planned soon and once all is good and verified, the K3 will become commercially available.

High Angle Solutions – CTOMS – T2-Harness

Wednesday, March 9th, 2016


We set out to solve the problem of wearing a chest or full body harness that incorporates into an armor plate carrier system. Typically a system like this would either go under the armor, making the high attachment point exit from behind the plate getting into the face of the wearer. The other more common option if for a system to go over top of the plate carrier and all the attached pouches. The problem with that is that it makes the pouches less accessible and when loaded can crush the content. Not ideal for things like first aid kits and even pressing the PTT switch on a radio.

We designed the T2-Harness to seamlessly integrate into a plate carrier. The webbing runs through the MOLLE in front of the armor, but behind any mounted pouches thus solving the two major problems. The T2 must be used in conjunction with either an M2 or G2 Harness (sold separately) as the only tested and compatible seat components, creating a Class 3 harness system.

The T2 uses the same convenient connection style as our patented M2 Harness system. Comfort adjustment is fast and easy while donned to transition from suspension to walking and vice versa.

High Angle Solutions – CTOMS – TRACE Systems Authorized Trainer Course

Wednesday, February 17th, 2016

TRACE Course Photo 1

The TRACE Systems Authorized Trainer Course is a 5 day program that covers advanced use of TRACE Systems. Topics include professional and hasty rescue systems with 1 and 2 person loads, guiding lines, high lines with reeves, multi-pitch work climbing, glacier travel and crevasse rescue among other topics. The 5 days of training will bring a unit/agency’s instructor cadre to the Authorized TRACE Systems Trainer level for the agency, and Instructor level for the Instructors, authorizing them to teach basic and advanced use to their unit after completing the online pre-course/pre-use packages. This course is ideal for military units requiring complex terrain negotiation, law enforcement special tactics units and even civil Search and Rescue Team. TRACE Systems is not to replace traditional systems, but to fill a gap, provide a light weight alternative, without compromise of safety or capability, when traditional systems are weigh prohibitive.

TRACE Course Photo 5

Venue’s for the training can be urban, mountain or a mixture of both depending on the agency’s mission requirements. A typical course will start with a day of basics, getting into the details and the importance of specific progression in the training when running a course. Glacier travel and crevasse rescue can be taught on a tower or rock. A glacier is not a key component to learning the systems. Two days of rescue systems follow learning professional rescue with one and two rescuers. Included in those days is high lines that can be used with a reeve for rescue, or for bridging in complex terrain negotiation. The fourth day will get into the process of climbing with the system, setting up fixed lines and the always interesting discussion of self-rescue. The work week finishes off, depending on venue, with a multi-pitch climb. And all this done on the TRACE Systems 6mm rope.

CTOMS Prodigy Pulley Vs Prodigy Pulley - PMP

The Prodigy PMP is identical to the Prodigy Pulley in dimensions and performance, however it features the addition of a Prusik-minding flange on one side. This flange adds slight weight to the device, bringing it up to 1.6 oz., compared to the 1.5 oz. of the original Prodigy Pulley.

It should be noted that the PMP is not a replacement for the Pulley. The flange does add additional versatility to the pulley, however the choice between the PMP and non-PMP style is dependent largely on requirement – capability vs. weight savings. TRACE Kits will continue to include the original pulley for weight savings.

High Angle Solutions – CTOMS – Tac Climbing Gear – Sling Set

TAC Climbing Gear Sling Set Complete Contents

The Tac Climbing Gear – Sling Set is designed as a solution to the rainbow climbing rack. Because color is a problem (see here), where CTOMS’ GREEN Kit includes subdued color anodized rock protection, carabiners and sling, it’s not always realistic to replace good expensive equipment prior to the end of its life cycle. A great interim solution is to use your rainbow cams, chocks and slings with the Tactical Climbing Gear – Sling Set.

This gear sling reduces color and noise signature with the multiple Climber’s Dump Pouches. The sling and padding component both incorporate PALS so that radios, chock tool holsters, even pistol holsters can be secured to the Gear Sling itself for light climbing configurations. If going heavier, the system can connect directly to an armored plate carrier PALS.

High Angle Solutions – CTOMS – Prodigy Pulley

Prodigy Micro Pulley Size Comparison

We first told you about the Prodigy Pulley at last year’s SOMA Conference. Back then CTOMS only had prototypes and called it by its development name, the Piccolo. The name was changed to reflect its impressive capabilities for such an unassuming, tiny device. Note the size comparison to a quarter in the picture, then consider the robust performance in the specs. This little guy is a game changer for micro-hauling systems, and while it is the standard pulley in CTOMS TRACE Systems kits, it will work with any rope up to 9mm. Ideal for crevasse rescue systems and ski guides.

The Prodigy was designed to accommodate three DMM Phantom Screw Gate carabiners in the eye, thus allowing it to be used as a carriage on a guiding line or high line using TRACE Systems. It uses a sealed bearing as opposed to a bushing that is typical in pulleys of similar size. What that does is create an efficiency of about 95% compared to about 75% in similar sized pulleys. Weighing in at only 1.5 oz. (43g) it has a strength rating of 24kN, or 5395 lbs of Force.

Prodigy Micro Pulley Alternate Views

During the pull testing to determine its strength rating, the failure points were the small ball bearings pushing through the sheave and cutting the rope at high forces (all above 27kN or 6070 lbs. or Force – the 24kN is a 3 Sigma rating). It was theorized that with lighter loads, it may decrease the pulley’s efficiency due to the small bearings indenting the inside of the sheave. So it was tested to determine strength deterioration after loads were applied. A peak load of 8.7kN was applied to the pulley and efficiency tested without any efficiency loss at all.

Detailed performance specs include:

  • Strength: 24 kN Rating, 18 kN Tangential Rating (side pull on the eye);
  • 95% Efficiency: (tested with 6 mm TRACE Systems rope and a 100 kg load);
  • No efficiency reduction after loading of 8.7 kN;
  • ~9 mm rope (If you’re using it with other than TRACE Systems);
  • Triple carabiner eye accepts up to 3 carabiners (DMM Phantom Screw Gate) for use on a high-line, etc;
  • Lightweight: 43 grams.
