Cadex Inc. – Surveillance Tools

Cadex Defence

You might think Cadex stands for Canadian Excellence once you get your hands on some of their kit. They have been building specialized equipment for some of the most exclusive customers in North America for some time and now they want to offer their products to a wider audience.

Of particular interest are the Modular Surveillance Rail and Spotting Scope Inverter. There seems to be quite a few companies coming out with similar products, but there are the real deal. They are actively in use by various organizations.


Cadex Surveillance Rail - Complete

It has been in production for around 2 years and was developed so a surveillance or sniper team could decrease the amount of gear they needed to carry by integrating a team’s organic equipment such as the same night vision (UNS) that you would mount on your rifle as well as using your spotting scope instead of purchasing (and carrying) specialized camera lenses.

Cadex is an interesting fusion of engineers, master machinists, and BTDTs. This team made sure all release buttons are easily manipulated in extreme environments such as cold weather and darkness and that every knob or adjustment wheel is pinned in place so you do not lose it by accident. The mount is CNCed from a billet of aluminum.

What’s really cool is that it mounts an M-4 rifle butt for added control in the prone. This also means it will mount to standard tripods or can be used with a front bipod and the quick detach M-4 butt.

Everything is designed to be modular and you can quickly remove any component say for instance, if you need only the day optic or spotting scope, camera, etc.

Cadex also manufactures interface adapters for the camera and spotting scope/night sight so there are no light issues.

Seen above is the Gen 1 model. Cadex is coming out with a GEN 2 that will have a universal camera mount in order to accommodate a wider range of cameras and night vision systems. They are also adding a Mil Std 1913 side rail for lasers, etc. The Gen 2 will be ready this fall.


The spotting scope inverter has been in production for about 4 years and was designed to give the sniper a lower head position. Mil Std 1913 side rails were added to accommodate IR lasers for identifying targets. The trick to the inverter was was to make one unit that fit the three different models (seen below) that Leupold made over the last couple of years.

They also designed a bow in the rails to prevent any loosening or shaking.

Cadex is constantly improving their products based on feedback from their customers and will be releasing a new inverter in a couple of weeks that mounts an UNS in front of the scope.
