More than i planned for - ATN ThOR 4 4.5-18x50mm Thermal Smart HD Rifle Scope

This scope has lots of Bells and Whistles. After mounting it on my AR-15 and familiarizing myself with it, I now understand that in daylight the scope only sees thermal images, not quite the view that I thought it would be, but still a good sharp view.
The scope feels solid, not a lightweight plastic optic.
Medical issues have left me as mostly a one handed shooter so I have the AR setup on a good quality tripod. When sighting in the scope; I find that the focus is critical at each distance. I was on the paper at 10 yards, backed up to 50 yards and had to refocus the front lens, I moved to 75 yards, refocused and again at 100 yards. Realizing the need to continually focus because of the unknown distance of an approaching target would be difficult with two hands. I sighted it in at 4.5 power for all distances. I do not know if the technique would be to focus on the target and then zoom the magnification in or out to keep it in view; does that maintain focus? I did zoom up to 18 power and found that zero was maintained but the pixelation at 18 power was not useable for me. Maybe if I was targeting something at a range greater than 100 yards it would look better?? I doubt it.
I do not see any value in the built in range finder, the new optional range finder accessory looks like it is more useful for those that use the information.
The "Oneshot Zero" worked well. i found that I had to correct it at each distance from my target upto 100 yards.
So far I have only used the "black hot" view. In Minnesota with snow on the ground there is good differentiation of thermal objects in black hot. I will have to play around with some of the settings as time goes on.
The built in rechargeable battery appears to add value. I am still using it from the first charge and there is plenty of battery remaining.
The scope is sold without lens covers, ATN's website might sell them. I will purchase lens covers for this scope, it is too expensive to not take care of it.
I am sure that I will enjoy using this scope, I may have paid for more "bling" than I will ever use, maybe the lower priced scope offered by ATN would have been a scope more fitting to my abilities. At 70 years old with 1 good hand and the other just a helping hand it would be great to just point and shoot! No fiddling around.
