Actually, we don't know why the Rescue Rangers
need the Infrared Night-Scope. Actually, chipmunks and mice can
see in the dark. But anyway...
Gadget made this invention
for night observation and succesfully used it on cases.
The Infrared Night-Scope is made from a metallic Z-tube, which is wide
at its end. At this end a lens system is located. The opposite end of
the tube has an eye-glass built into it. Imaging focusing controls are on the body of the tube.
