Todd. I have a yardage pro 800 that can get hard targets (tree, rock) out to 840+ yds. Haven't had a chance to try it on game, but did range a couple of cows at just over 400 yds. Wouldn't read at 800 on cows or big round hay bales. If the target reflectivity scale at the top reaches 35-40% reflectivity, I can get a range reading. It barely gets enough to read at 840, tho. Watch your reflectivity scale.
It is important to get a rest and hold very still. Also, JECustom had a yardage pro 400 that had a dislocated crosshair. He found where it actually was by ranging a windmill tail against an open sky. It was way off.
The 1500 should do a lot better than my 800 on game. I'd call Bushnell.
Good luck, Tom
