Thread: Clip on thermal

I trialled one there are several quirks with these which ken advised me of.
Use it in a scope with as low magnification as possible ideally 1 or 2x, you are looking at a screen image and enlarging that so it gets grainy very quickly even with a 12 micron detector. It was acceptable at 3x much like an early 25 micron thermal but anything more and it's fuzzy blobs and the lines of the screen. Also you are onky enlarging part of the screen at higher magnification so you can't see the menus
Mounting, again you are looking at a flat screen, if it's optical centre is canted slightly off the bore axis you won't notice through the scope. I did repeated detach and reattach tests and there was a shift in poi of between .5 and 1.5 mils each time it was refitted and this was in a random circle. I believe this can occur with all makes and depends on the design of the adapter and lock rings as much as operator skill and may or may not be an issue for you if shooting at big things up close.
Overall I was impressed with it as a handheld as it beat my pulsar xq28f hands down but as a scope not so much.
I endorse zeropacks comments on the nv clip ons they retain a lot more of your scopes performance.
