I see that rangefinders are now calculating the angle of your shot as well asdistance.

how important is"Angle compensation" for bow hunting?

It seems like a great concept, but is it necessary or worth the extra $$$$

when shooting from a treestand it shouldnt make enough difference to justify the extra money however, i recently went on a sheep hunt and acr can make a huge difference on vertical shot at long distances. I found the rangfinder i took (leopold) to be very slow and i didnt like the modes it had

I agree with bowhntt. I purchased the Bushnell elite 1500 with arc this year. If your just going to be bow hunting i wouldn't spend all the money. One of my stands is about 25 ft high and when ranging a deer at 19 yards, with the angle calculated in was 18 yards, even when shooting almost straight down there is not much difference. But i think gun huntingiswhere it will shine, the rangefinder comes with aballistics chart, you find what corrolates best with the round you are shooting and the rangefinder will tell you how much bullet drop there will be along with compensating for angle.

Im using the RXII. Not sure its right either. I shot an arrow at what it ranged to be 43/40. It didn't 'feel' 40, So I aimed for 35 and was dead on. On another shot I ranged 52, used my 50 yard pin and hit 2 feet low!?

Both shots were from 23-25 feet up. I've got it set on the fastest bow speed. Maybe I need to read the manual again. I haven't seen more than a 4 yard difference from a tree yet.

I have a cheap Bushnell Yardage Pro. I never had any problems with angles for bowhunting. It doesn't calcualte the angel but I've never missed with it either
