The larger objective helps under a similar theory as a day scope: the larger the objective, more return is allowed to reach your sensor plate for processing. Where it differs is that the pixel pitch of that plate (all else being equal) has as much to do with what gets processed and seen at the eye end. In this case, SMALLER pixel pitch (12um vs 17um) is better, as there are more sensors on the same sized array, if they’re smaller in size. More sensors is a good thing. 12um in a 25mm device often detects and resolves as well or better than a 17um, 35mm device. A 12umx35mm will perform as good or better than a 17umx50mm objective device. It becomes more evident when conditions aren’t ideal: high temps, high humidity, fog, etc. What’s interesting is that until Pulsat started using 12um on some of their 384 devices, they trash talked other makes using the smaller PP ‘as nothing but a way to reduce cost by reducing germanium objective sizes’. While smaller PP can make smaller objectives perform like larger objectives, the truth is that smaller PP just works better.

I look through my scanner with my left eye to keep my right (dominant) eye free from the night blindness.

^^^^….that’d just mean I’d burn out both eyes, because I’m on the scope a lot, too. My dominant eye just stays shaded. My off eye is for walking. wink Same way we used to used PVS-14s when they were issued.

I thought that they were not Allowed in most states, they would fall under the category of Electronic Device?

I think on private property you can do what you want in parts of Alabama, no warden is going to bust you for shooting coyotes at night that are after your livestock anytime day or night you shoot them.

Again: In AL there’s a permit/season for it. $15 added to your license.

Yes,

My AGM Taipan 15-384 has just about retired my Leica's.

Amazing what you can spot/observe that one could/would never using any traditional alpha glass. Nothing that radiates a temperature above ambient and is not behind solid objects can hide. I don't recommend it but even looking into direct sun, morning or eve works with thermal.

ya!
