Negatif, though I haven't tried that setup in a "Noah's Rain" ... so not sure it is all water proof. And haven't tried at below zero temps IIRC.
If you get something like this, you have to decide if you want the newer 4.5x base magnification bushy or the older 3x model. I got the 4.5x model before I knew the 3x existed, so then I got the 3x. The 4.5x also has a digital recorder, the 3x does not. On my land the 3x is better as I live in a valley along a creek and have a lot of close terrain. But if open terrain the 4.5x or even the 6x (I think there is a 6x) might be better. There is digital zoom. The image is actually amazingly clear when there is one.
The T-20s or "Evola's are available on Amazon, I think for around $30 these days.
It uses 4 x AA batteries, so if you will change batteries at night in the field, you need to practice up in the house without looking. Well first maybe 10 times looking and then maybe 20 times without looking.
