The CHAD Iris | Cold Harbour Supply The CHAD Iris | Cold Harbour Supply
All In Focus
If you’ve used night vision for long, you’ll know the frustration: focus on the distance and anything close up, like a map, your kit or the ground at your feet, turns to a blur. Refocusing the objective every time is fiddly, especially on an articulating binocular or in adverse conditions.The CHAD Iris solves that with an adjustable iris that screws onto your objective lens. Close it down slightly and your depth of field opens up, so near and far stay sharp together without re-adjusting the main lens. Open it fully and it sits clear of your lens, with no loss of image.
It’s useful in bright conditions too. Closing the iris cuts the light reaching the tube, giving auto-gain devices a form of manual brightness control and reducing bloom around streetlights and other bright sources. Fully closed, it works like a pinhole day cap, so you can leave it fitted. For long-term storage or extended exposure to light, still use a proper lens cap.
The front lens also protects your iris and objective from dust, debris and impacts.

NOODL Lanyard Retention | Cold Harbor Supply NOODL Lanyard Retention | Cold Harbor Supply
Simple Insurance For Your System
Night vision is expensive, and helmet mounts can and do let go. The NOODL (Night Observation & Operations Device Lanyard) is a simple, low-cost backup that keeps your device tethered to your helmet. It holds it steady while deployed and stops it hitting the ground if it ever comes free.
Unlike Velcro straps that snag on branches and brush, the NOODL attaches directly to a helmet hard point. A Cordura loop goes under your front helmet bolt, and an adjustable shock cord clips to your device. Installation takes a few minutes, and once it’s set up you’ll barely notice it’s there.
What’s new in V2
- Cordura loop by Macabre Solutions for the front helmet bolt
- Lower-profile, easier installation
- Configurable for any helmet attachment point
KEY FEATURES
- Keeps your device secure and steady when deployed
- Adjustable shock cord tension
- Fits most helmets via the front ARC rail bolt
- No Velcro to snag on vegetation
- Everything you need to install is included
IN THE BOX: 1× 12" elastic shock cord, 1× 0.6" black-oxide split ring, 1× 1/8" mini carabiner, 1× Multicam Cordura tether loop (Macabre Solutions), and 2× heat-shrink pieces.
Note: single-point retention. For full tension, use two. Not recommended for airborne or high-angle use.

Compact Rugged J-Arm Mount Compact Rugged J-Arm Mount
Compact Rugged J-Arm Mount
Sale price £116.00 Regular price £145.00The Best Way To Mount Your Monocular
A J-arm is what holds your monocular in front of your eye, and when it’s stowed, a bulky arm sticks out, snags and adds unnecesary weight. The Compact Rugged J-Arm is built to stay out of the way. A central articulation joint lets your device fold up close to the helmet, reducing snag risk and the load on your neck, while staying rock steady when deployed.
It’s machined from 7075-T6 aluminium for strength without bulk, works for either eye, and adjusts across a 55–75 mm IPD range to fit most users. It fits the PVS-14, the Nocturn Talon and other monoculars with a standard 1/4-20 mounting screw.
KEY FEATURES
- Stows close to the helmet to reduce snagging and neck strain
- Central articulation joint for a stable, steady hold
- Left or right eye use
- 55–75 mm IPD adjustment
- Machined 7075-T6 aluminium
- Fits any monocular with a standard 1/4-20 PVS-14 interface
- Lifetime warranty

Wilcox L4 G24 Night Vision Mount Wilcox L4 G24 Night Vision Mount
Wilcox L4 G24 Night Vision Mount
£470.00The L4 G24 A Battle Hardened Mount
If you’ve seen night vision on a helmet, there’s a good chance it was sitting on a Wilcox. Developed with US and NATO special operations units, the L4 G24 has become the mount many others are compared against. It’s dependable, easy to adjust, and fits a huge range of devices.
Getting your device positioned properly makes a big difference to comfort and image quality, and the G24 makes it easy. Height, fore/aft and tilt can all be fine-tuned, with large controls you can work one-handed, even with gloves on. Once it’s set, it stays set.
The breakaway design is there for your safety: if your device catches on something or takes a heavy knock, the mount releases instead of transferring the force to your neck. When you don’t need your night vision, it flips up and stows close to the helmet.
Who it’s for
- Anyone who wants a proven, widely supported mount they won’t need to replace
- Users running dovetail devices such as the PVS-14 (J-Arm Mounted), Katana, Raptor or Nighthawk
- Those who value adjustability and breakaway safety over the lightest possible weight
KEY FEATURES
- Field-proven design, used by US and NATO special operations forces
- Height, fore/aft and tilt adjustment
- One-handed, glove-friendly controls
- Breakaway design to reduce the risk of neck injury
- Flip-up stow, low profile on the helmet
- Dovetail shoe interface, compatible with a wide range of devices
- Hard-anodised aerospace-grade aluminium
SPECIFICATIONS

Nocturn Industries Alpha Mount Nocturn Industries Alpha Mount
Nocturn Industries Alpha Mount
£445.00All The Mount, Half The weight
The mount may be the part of your setup you think about least, until it wobbles, slips or adds weight you didn’t need. The ALPHA (Adaptable Lightweight Powered Helmet Arm) has all the adjustment of mounts like the Wilcox G24 and Cadex at a fraction of the weight. 80 g against 180 g+ for a Cadex is a real difference over a long night under night vision.
What sets it apart is choice. The ALPHA is the only mount that can run push-button stow and release or be converted to force-to-overcome, so it works the way you prefer, or the way your kit list demands. A bearing detent paired with the push-button lock holds your device rock steady, with very little of the wobble you get from cheaper mounts.
It’s also designed to feel familiar. The controls sit where you’d expect from legacy mounts, and the large buttons are easy to find and press with gloves on. A long 41 mm carriage throw means you can position your device properly, even over glasses, eye protection or a respirator.
Who it’s for
- Anyone looking to cut weight from their helmet setup
- Users moving on from a G24 or Cadex who want the same adjustment in a lighter package
- Teams that require push-button or force-to-overcome operation
KEY FEATURES
- 80 g: one of the lightest fully adjustable mounts available
- Switchable between push-button and force-to-overcome operation
- Bearing detent and push-button lock for a solid, wobble-free hold
- 41 mm carriage throw for eyewear and respirator clearance
- Large, glove-friendly controls in familiar positions
- Breakaway design
- Adjustable rubber pads for a secure fit on any shroud
- CNC-machined 7075-T6 aluminium and 17-4 PH stainless steel
- Lifetime repair or replacement warranty
