With all of this talk reguarding Thermal systems I got to looking at several different options 2 that have caught my attention are:
ATG-7 this is a themal binocular looks very similar to a PV-7.  This obviously limits your abiltiy to mount to the weapon.
TADS 850 this is a weapons mounted option that works with several scopes.  
I like the option of the ATG 7 because it is compact and it is small.  I loose the weapons mount option with it.  The TADs unit is awfully BIG & heavy.  Man it is impresive though.  I'm not sure which one is what I'm looking for.  I've been looking into thermal sights for some time, and nothing has just jumped out at me.  Wanted to get some input from you guys.
