What brand thermal if you would share?I can see alligators with my thermal in black hot with only their head exposed. Figured this out while running through all the color palettes. Beavers shine like a lantern in Red Hot mode. I haven't caught one swimming to tell you for sure but I would think they would show very well compared to a gator
AGM Adder TS 50-384
of course depends on size of head but 150 yards or so and its much easier to ID in slick water. Glassy surface
It would work. There are some interesting options for that type of work. But I wouldn't know about all of that.Dynamite works better for beaver....never used it on gator....interesting idea....
