There are basically three ways folks hunt with I2 Night Vision.
1) With dedicated Night Vision Scope, like an M845.
2) With a head mounted mono, pair or quad unit, using an IR laser and point shooting whatever the laser is pointed at.
3) With a Mono behind a Red Dot.
You need to decide how you are likely to hunt and then go for one of the above. Generally speaking, a PVS-14 can be used for 2 or 3, so that unit is a good starting point.
