I double checked and mine is a trail sentry, not a trail scout. Not sure if that makes any difference on battery life or flash range though.
This is one of my favorite trail camera pictures and it was taken with it about 100 yards from my house at a wildlife pond I built.
I wouldn't buy another one and would gladly sell the one I have if I got a decent offer for it. It spends most of the time in the garage on a shelf.
