Fogging Thermal

[chthump]

Is it OK to use a product like anti-fog RainX on the thermal scope lens (closest to your eye) what ever you call it.

This blast of snow and cold air in NE Texas makes the thermals fog up within 5 minutes of scanning.

I haven't tried Rain-X. Let me know how it does. I use some generic eyeglasses anti-fog stuff I got at the glasses counter and it helps. It also helps not to exhale into the eyecup, LOL, something I am guilty of doing.

The eye piece is just a normal lens.

 

[chthump]

Yep, no exhaling, its more of an eye contact to scope type fogging

You breathin' through your eyelids again? I always used "Zook" for my motorcycle gear, to keep it fog free. Worked well.

I remmber that from Bull Durham. Never learned how to do it.

I guess , last night I had about 3 or 4 minutes before it fogged over, I am pretty disciplined covering my light escaping, so it's sealed when it's on.

My left eye fogs up everything when it's cold. Sunglasses, goggles, etc...

Maybe after a shot of whiskey. lol

I found the best thing is not to go hunting when it is that cold. lol

That is true, the shot of whiskey didn't help the fog either

 

[Brian Shaffer]

You have to drink enough whiskey until your vision is as foggy as the scope, at which point you reach visual harmonic synergy and all things will become clear to you.

We have to deal with the cold temps predator hunting up here. For a scanner, I keep it fiurther from my eye. It'll still fog from time to time, but waving it in the air will clear the fog. I haven't had an issue with my MK II, which has a shuttered eye cup, but I'm not looking through it for long stretches.

If I'm using helmet mounted PVS 14s, I used to roll the eye cup up and set max distance from my eye. Ended up liking that so much I just leave them that way.

Never tried anti fog. Will though!
