Application Guide TA4

The thermal image scope is suitable for any user who wants to add thermal images to their rifle scope. With the TA4 series you can transform your rifle scope into a thermal scope. You cannot use the TA4 series individually as a rifle scope because the thermal imaging camera itself does not have a reticle. Use the reticle of your rifle scope for aiming and shooting.

Using the supplied eyepiece, you can also use the TA4 series handheld and look through it with your eye. You can also place the thermal imaging camera on a tripod (optionally available) through the 1/4" thread at the bottom. With two CR123A batteries (not included) you can use this thermal clip-on for up to 3.5 hours. A universal battery charger is included to charge your own batteries. If you want to view images in real-time on a screen, you can use the included video-out cable.
