2 Description
MATE series are all-new generation front attachment designed as the
infrared expansion device of the day light optics.
Different from the night vision device based on image enhancement, MATE
doesn’t need external light source and isn’t influenced by strong light
exposure. It can be used in the night or bad weather conditions such as
fog, rain, smog and can detect the objects through obstacles such as
branch, tall grass, dense bushes and so on. MATE has a wide range
application including night hunting, observation and terrain orientation,
search and rescue operations.
Using the MATE Series Front Attachment includes several benefits over
night hunting with traditional optics or even the night vision devices.
Attaching the MATE Series to a traditional scope delivers the same
creature comforts of shooting with day optics you are accustomed to,
including your existing reticle and eye relief. The MATE Series Front
Attachment even allows you to continue utilizing your riflescope's variable
magnification
