The FH35R thermal spotter features a 640x512 12 micron sensor, with
an integrated laser rangefinder, to deliver incredible performance
capturing fine details at precise distances with the capability to
detect out to 1800M man-sized targets.
The FH35R is equipped with 12µm 640×512 pixel
pitch high-resolution sensors featuring NETD =35mk and uses a 1024x768
resolution OLED display with a 3.4x to 13.6x mag range.
Coupled with the optimized image algorithm, it
creates stunning clear imaging now with replaceable battery pack modules
for quick change power in the field. (Two batteries included as
For a better visual
experience, Finder II supports switching between cold and warm image
hues. With the cold hue setting, users experience visually clearer
imaging quality with rich details and highlight targets. The warm hue
setting generates softer imaging to avoid visual fatigue brought by

This is a review of the InfiRay FH35R Thermal Monocular.
These devices are typically used by hunters for scouting before and
after the shot, but there are many other uses like finding missing
persons. I really like this InfiRay. It has a good image quality, it’s
easy to use and it’s relatively small and light. On top of that, there’s
a Laser Range Finder (LRF) built-in, and while not
cheap, the device is reasonably priced. It’s been my companion on
several driven hunts, and I’ve used it to scout various areas to
discover the performance and possible limitations.
