So the NO Panther 336 is $6200.
Even then, the native mag is not substantially more than a 336 Zeus 3-12x50 17 micron that is about $3800 (MAP)
A Pulsar Apex XQ50 is 384x288 resolution (more) 2.7-10-8x42 (less) 17 micron that is $2800
A Pulsar Trail XQ50 (c.f. with Apex on specs, but many more features) is $3800
Armasight Zeus 640 3-12x75 (ALL MUCH BETTER) 17 micron is about $6500
So the Panther isn't going to be any sort of cost effective bargain for getting 3.5x @ 336 resolution.
Think of it this way, you could buy a Pulsar Apex XQ50 and a reasonable thermal spotter (or another Apex that could be used as a spotter or put on a 2nd gun) for the cost of the Panther.
