## Using a Range Finder From a Tree Stand? Little Help please...

I found a laser range finder for pretty cheap.. Like \$100 bucks... But it isn't one of the fancy ones that have the ARC or adjust for distance while elevated. How much of a difference would something read on a range finder with the compensator built in than without. For instance, If I'm 20 ft in the tree, how many yards off will it read at 10/20/30/40 yards... I usually don't shoot past 40 hunting anyway... thanks

3. All "ARC" does is find the actual horizontal distance between you and the object. You can use the right triangle equation [(A x A) + (B x B) = (C x C)]. "C" would be the hypotenuse and would be the reading that your rangefinder would give. Here's an example of say 21 feet up in a tree (equals 7 yards) and the object was 20 yards away.

A = distance up in the tree or elevated side of a right triangle
B = horizontal distance between you and the object
C = Line of sight distance or distance your rangefinder would give you

(7 x 7) + (20 x 20) = (C x C)
49 + 400 = C x C
449 = C x C
Solve by finding square root of 449
C = 21.19 yards (which is what your rangefinder should read) instead of 20 yards that is the actual distance, difference of only 1.19 yards

*also note that the further the object is away the smaller the difference will be because there is less of an angle

Example 40 yards and same height

49 + 1600 = C x C
1649 = C x C
Square root of 1649 = 40.6 yards, meaning only a distance of .6 yards between line of sight and actual distance apart

If your only 20' up, and unless you are on the side of a big drop off, you can subtract about 1 1/2 yds and be fine.

7. what he said if you are only 20ft then dont worry about it

I agree, or just do what I do, climb up the tree/stand and make a mental range card of your area by ranging different trees at eye level from the stand.

It won't be much of a difference unless the deer is right under your stand. But, you need to aim at the horizontal distance. Which means, even if you are 20 ft up a tree, and the deer is 6' from it, your shot is only 2 yards.

If you have a question about the distance, range a tree near your shooting lane at your level. After, range the base of the tree and that would be the difference(as long as the tree is straight). I have done that with my RF without ARC. As stated above, not much of a difference to matter.

Rayhunts, Great pointer on the range finder. Never thought of it like that. I have never used a range finder with ARC and kill almost every deer I shoot at from a tree. Its more about practice, deer angle and knowing your personel limits. Take a couple arrows with you on your hunts that have judo points on them. When you get ready to climb down, take a couple shots at a stick or something on the ground. This will show you how you will hit at different ranges according to what the range finder is displaying. Ground feeding squirrels are great practice.

Yep, that works too.

I have a Leupold with the ARC technology. It really does not make much difference at all bowhunting. I wanted one to play with that would do everything and use for golf also.
