Ferret 240
(no longer available)
Handheld IR Viewer

Own the night with the Ferret 240

Why Infrared? Why not Night Vision?

Infrared or thermal viewers let you "see" in total darkness. Unlike night vision viewers Infrared viewers aren't effected by extraneous light sources, such as headlights or flashlights. You won't experience "blooming" as you can with non-IR devices.

The Ferret 240 provides a new level of performance in Handheld IR viewers.  Its combination of small size, low weight, rugged construction, battery longevity and price are unmatched in the industry.
