I would agree with turkeyhunter. I have both and I use them in different situations. Thermal has it's pluses but if I had to hunt with only one I would chose the NV for the positive ID. Thermal is always an image as has been stated many times. Twice, I though I shot the nearby farm houses pet dog after it started yipping. Sounded more like a dog than a coyote. Quite the sinking feeling. Never so relieved when I found it to be a coyote. I wonder if there would have been the rush to thermal there has been if the NV scopes had recording, PIP, and variable magnification. That's the one thing I wish NV scopes had is the variable magnification although the 4X has always been more than adequate. I guess you have that if you want to go with a clip on. BTW, I use a gen3 D740, Trail XP50, and also have a Nemesis WP gen 2+. I ALWAYS no what it is with the NV scope. The biggest advantage and game changer has been thermal to scan with.
