Went through this with friends and family. Mulled it for years before I made my choice and purchased a thermal scope, had a thermal monocular/ night vision long time. I found a lot of people wanted me to buy what they had, it was the greatest. It was the only one they had ever used.
Decide realistically what your base magnification needs to be. What range and how much detail do you really need for your targets? Are you shooting at 25-50 yards at moving targets? Or popping pigs under feeders and called coyotes at 100-200 yards? Longer?
I take more shots at feeding hogs and called coyotes. Potentially shoot exotics and need the detail. I like to be able to tell a boar from a sow and shoot the biggest sow in a sounder at 100-200 yards. I really like to have the ability to identify and shoot raccoons and varmints at 100 yards. Head shots. I seldom get more than 3 shots off due to the amount of brush. I went Halo LR. Fits my needs.
If I was hunting grain fields and shooting lots of moving targets my needs would be different. Yes you can digitally zoom, but it is not ideal. You end up shooting center mass of the blob.
Decide your needed base mag. Then find what's in your budget. It will really narrow the field for you. I have seen more thermal scopes for sale/trade because folks didn't correctly identify their needs before the purchase. Most folks will gladly let you look through their scopes and answer questions. At one time I had a group with about 6 different scopes out on my range after dark, swapping back and forth. Had a hog in a trap and raccoons under a feeder there. It was great and finalized my decision. A few guys changed their minds on what to buy.
If you make the correct purchase it is a life changer. Your hair will come back thicker. Your cholesterol will drop. You will be wanted by all the women,,,and half the men. Good luck. You owe me $0.02 Rev P
PS. I covet the black coyote.
