arc rangefinders

I need some help!! looking for a range finder w the arc (angle range compensation)or tbr (true ballistic range)capability i looked at the leupold rxII and i read the reviews and alot of people say its too hard to use and the tbr doesnt work well. from experience has anyone found that the distance is that much different using a range finder without this feature vs. one with the feature. im looking to spend 200 300 on one

At short ranges, ARC doesn't matter that much and at long ranges, most ARC range finders won't range. You will be much happier making a simple chart on the side of your rangefinder with the cosine of several common angles like. 15 = .97, 30 = .87, 45 = .71, 60 = .5 Just estimate the range in your head. Like a deer is 25 yards away by rangefinder. . .I'm 20 ft off the ground. 25 * cos 15 = 22yds This is my 2s guess.

Actual is 25*cos(arcsin((20/3/25)) = 24 yards. With my crossbow, my 22 yd guess kills 'em everytime. This is why ARC is of no value. Now if it were on a 2000 yard rangefinder, then we'll talk.

Unless you are taking longer shots in very steep mountain terrain,it simply isn't necessary.

I have the Bushnell Scout ARC and my brother has the Nikon without. We both got on top of the roof to shoot our bows (about 15ft high). We shot at a target out to about 30yds. There was about 1-2 yds difference between them. My opinion is if you dont live in Colorado, then you dont need ARC, and I have one.
