Thanks for the podcast. Very informative and my biggest piece of advice is to save-up for that thermal purchase whether it takes you months or years. If you skimp, you will regret buying a cheap thermal. I have called in coyotes, bobcats, shot skunks, racoons, armadillos and gives you a gauge on looking at the wildlife when they would normally have the advantage. I have taken people that don't have thermals and allowed to shoot mine but don't advise doing that as missing, misjudging distance, or muzzle discipline is a challenge. Missing a kill only educates the wildlife.
I have owned an ATN Thor 4, 640, 4-40 zoom for 2 years and question is subjective. In optimal conditions, yes. Differentiating between a hog and bear is easy but high humidity, what thermal you are using affects the quality of your picture. Humidity changes the quality.
