The latest thermal spotter from IRay has arrived! The IRay CAL19 Cabin is a bit more unusual than most, as it appears to be a bit of a crossover concept. Paul Austin investigates...

All the typical IRay features but with a twist, which I suspect is meant to appeal to not only shooters but also the wild camping crowd and outdoor adventurer types.

From a purely technical perspective, there’s nothing particularly new, with the tried and tested IRay 384x288 sensor at its core, but when it comes to form factor it is definitely a bit different. When I initially opened the box, there was a bit of head scratching as I puzzled over what appeared to be an LED torch plonked above the main objective.

Yet more innovation in terms of power with IRay opting a 3100mAh battery (two of which ship with the device) plus an optional accompanying external charger, both of which are very reminiscent of Pulsar’s APS battery system as used in the Axion range.

Below the objective, there’s an unusual rocker lever focus, which as well as being a bit different is also surprisingly good and makes the unit particularly easy to operate single-handed. The rest of the controls sit on top of the device with four buttons allowing control of the core functions, as well as navigation and selection within the main and sub menus.

All the familiar IRay features are on hand with multiple colour palettes, a PIP screen, a stadiametric rangefinder, video and pic recording, motion sensor and compass, a 50Hz refresh rate and Ultra-clear (high contrast mode) and of cause WIFI connectivity to the app for remote control and file transfer.
Image quality is good and what you’d expect from a smaller sensor with a 19mm lens, but like all smaller lenses it’s likely to suffer a little more than a larger variant in poor conditions.

The NETD rating is <40mk, so reasonable. It’s probably best described as a good all-rounder in terms of thermal performance. The mag range, however, is spot on, with a base of 2x stretching to 8x via digital zoom.

For me, the jury is still out regarding the LED torch, although admittedly, it is handy to have a focusable torch in hand when picking up at the end of the evening or tracking shot game, not to mention navigating your way back to the vehicle after hours, so it’s perhaps not without its uses.

It’s an all-plastic affair, but the build quality is good. It handles nicely and accessing the various functions is very intuitive. A slightly higher spec finish on some of the metalwork would have been nice but that wouldn’t be a deal breaker for me. It’s compact, fits nicely in the hand and has a lot of features packed into a very small footprint.
