My experience with night vision equipment is relatively limited. I have run BNVS in a helmet rig with weapon-mounted IR laser/illuminator setups in the past, and that was alright, but did not offer the precision I was looking for. Certainly was great for walking around, and were I in a run & gun type scenario at night, I think I would really like that setup. Though when it comes to vermin control, I definitely wanted something a bit more precise.
I'd love to hear what someone has to say regarding clip-on thermal sights. I played with a few at SHOT show last year, and the Eotech LWTS was the most impressive unit I handled at that time, but I didn't get hands on all of them. I really like the idea of having a dual-role thermal that can work in front of a day optic as a clip-on, but can also be mounted as a stand-alone thermal sight with it's own reticle.
Some requirements I'd be looking for would be:
- Maintains zero.
- When using as clip on, doesn't shift day scope zero, or is at least easy to zero and is repeatable.
- Doesn't need frequent calibration when in use.
- At least 6-8hrs of continuous battery life.
- Works as clip-on or stand alone sight.
