I just replaced the bushnell pro scout 450 with the elite 1500 arc. I couldnt get the 450 to range with consistency past 180 yards so I sold it. I chose the 1500 partly because it was on sale- the other in my selection was the Nikon monarch.
I've had great luck with my Nikon Monarch 800. What you need to watch in the fine print is max rating to a nonreflective target. I once ranged a white building at over 1000 yards with mine, but if it had fur on it it would've been a lot less. It's sort of like the "30 mile" GMRS radios -- some manufacturers will throw out a performance number, but when you peel it back you find that it's under optimum conditions -- in the case of a rangefinder, a highly reflective target in low light on a very clear day with no moisture or dust in the air. When I shopped for my rangefinder, I went with what I thought would be the maximum range I'd be comfortable taking a shot from under most field conditions, added some "stalking" range, and then doubled it to account for atmospherics and target reflectivity.
If you want to properly preserve velvet antlers, you will have to inject & brush them with formaldehyde or some of the new less toxic chemicals (4 in 1 solution works great as does Knobloch's antler in velvet tan) as its easier to use however, both will work.
First, using rubber gloves take a razor blade and make small incisions at the tips of all points about 1/8". Next hang the antlers upside down, allowing the blood to drain. Starting at the bases inject the solution into the...
