i have hunted for several years but mainly from a ground blind, dnt relly know how to ask this question where it makes sense but hope someone gets it, i know what 20 and 30 yard distance is from ground level but what about from 15ft in the air do u still calculate the yardage the same from in the air liking stepping off the yardage from the base of your tree, hope that makes sense,,thanks for your input
I use one of the ARC rangefinders and from my 15' stand the yardages you mentioned are about the same as if you were standing on the ground.
Gravity is a constant becuase of that the projectile will drop in the vertical axis as it travels through the horizontal axis. So you need to range in in steps from the bottom of the tree not the line of sight from the platform to the ground. all your worried about is the horizontal aspect of the shot not the vertical.
It is about 2 to 3 yards more. there is a formula, X squared + Y squared = Z squared Example is 5 squared + 12 squared = Z squared 169= Z squared Z= 13 Hope this helps.
Good question. No you don't. Make an investment and buy a range that takes angles into it calculations. In other word, you might be 35 yards in a straight line, but due to tragetory, you would have to use your 30 yard pin.
You would have to be 54 ft in the air for that scenario! Lol For treestand hunting the difference will be neglible
Mark your yardage before you make your way up the tree...If you range once in the tree you yardage will not be as accurate and you will miss or not hit where you wanted to.....
Actually, Salbo is mostly correct. That said, the difference you will see will be miniscule. Let's take 40 yard shot as the example. Say you're 21ft up a tree (easier math). So you have 7 yards, and 40 yards. So the distance to the ground at the 40 yard marker is actually 40.6 yards. Now, if you think that makes a difference, you're mistaken. Human error will account for more missing than 0.6 yards will. Even if you were 15 yards up a tree (45 feet), the difference would only be 2.7 yards. Hardly enough to make you miss the shot. So, with that information, you can now see that walking off your distances is an easy method, and is accurate enough that you don't need to spend $$ on a rangefinder. I'd buy a range finder if I was hunting elk at 1000 yards, and that's about it. We actually do something that makes this even easier. When we're sighting in our bows, we do it by "steps". So, we walk off 20 steps and set our pin. Then, when we get to the woods and mark off our distance markers, we take 20 steps and tie some orange tape.
This is what I recently did except I used my range finder. I like your technique better though, plus its hard enough to draw the bow on a deer undetected without adding in the extra movement using the range finder to help judge your shot.
I am glad I read this thread because I have never hunted with my bow yet and would have figured the difference would have been more. I did the math and here is what I got - rounded off to the nearest tenth of a yard. Let's say you are 16 feet up in a tree. I choose 16 feet because it is a popular height for a store bought tree stand, and beyond this height I get nose bleed. At 20 yards your actual arrow travel will be 20.7 yards. At 25 yards your actual arrow travel will be 25.6 yards. At 30 yards you actual arrow travel will be 30.5 yards And at 40 yards you actual arrow travel will be 40.4 yards. From this you can see that the longer the shot, the less difference it makes - although it doesn't make much difference anyway, since from 20- 40 yards we are only talking about 3 tenths of a yard. Before this thread the range finder was on my Christmas wish list - now it is not. I hope my math is correct - it has been a long, long time since I have been in school.
You are absolutely correct.... ON LEVEL GROUND... now take sloped land and it increases up to and beyond 5 yard differences.. when I was in IL I was on a steep side hill.. I ranged trees at the base and the tops from my treestand.. at times there was 5 yards differences, enough to make a miss a miss. The arc range finders would have been invaluable for me on that trip, my range finder, the original Bushnell 400 is not an arc... they do have a use.
As with shooting a rifle ..extreme angles will cause the fired projectile to impact high on the target, as in hunting from a elevated position or standing on the ground shooting squirrels with a 22 The easy answer ..as long as you aim at the lower 1/3 of the target you should be fine..just always remember when shooting uphill or downhill your bullet or arrow will hit a little high Sent from my DROID X2
