I didn't measure to the ground. I kept the end of the string roughly 3ft off the ground where the killzone of a deer would fall at. I would then put my marking tape on the ground. (if the deer is standing on my 30 mark his vitals will be roughly 3ft off the ground standing on this mark keeping the distance the same and shot angle the same)

I am just measureing distance from my seat to where ever the 10, 20, 30, and 40 yard mark would be at 3ft off the ground from the angle I would be shooting at from 15ft up in a tree. The line was premarked for the yardage before it ever went up into the treestand.

Now if I measured from my stand seat to the ground yes it will be off. From the base of the tree out it will also beoff..

Both blue lines are the same legnth but the angle has changed making the distance slightly different.

That pic shows exactly what I am talking about. If you measure from your stand with a tape as you did or with a traditional range finder you see by that pic what you get. You are shooting by the distance in the bottom pic thinking it is that far but when you are measuring at an angle you are really not that far. By the tape being on a angle you think it is twenty, but really only 17 or so on. But by the bottom pic you can see you where aiming longer then you needed to. Thats why alot of guys think they hit high when being up in a tree. Thanks for taking time to make the the pics, it helps.

I mark all my yardage from thetree stand.

Hotburn76, I no longer have the PHYSICS of MATH to prove the point but here is the general facts.

When you shoot uphill or downhill, GRAVITY does not have as much effect on your arrow as it would if you were shooting parrallel to the earth. Because of this, your parallel shooting would have a greater drop then if shooing uphill or downhill.

Therefore, if you measure from your seat when up in the tree, you will hit higher then if you were standing on the ground for the same distance. But if your measurement was from the base of the tree (not your seat high in the tree), your shot from the tree stand will be a little further, therefore the extra distance will compansate for the point of impact being a little high (that is if your not too high or shooting great distances). FOr the extra high treestands or longer distance shots you will have to aim a little lower to compansate for the higher point of impact.

Remember that the difference in the points of impact is not very much (at normal distances), we are probually only talking about 2 or 3 inches at most (depending on your bow poundage).

BUt if your bow is sighted in on the ground and then you shoot from a tree stand (same actual distances) you will hit high.

Hope this helped.

I am not a physics major either, or a minor, LOL,butI know its not worth arguing with friends over. I, from my own experience have never seen a difference, it still hit the circles on my block target. If its high it has to be less than a inch. It was the same way with all three of my CB's. My CB could be different, don't know. I don't know how much you are able to practice from a elevated stand, most guys who like to talk about it when asked the only time they have shot out of stand is at deer and never target. Like I also said if you use a old range finder you will also think it is high since you are measuring the angle and not the true distance. Here is a pic that Leupold sells its 300 to 500 dollar range finders with and they use this to show it. I am lucky since I have a nice flat shed roof 22 feet in the air and I can do alot of comfortable rest shooting off of and see no difference, alot of guys only have stands to do this and don't get to do it that much. Last time posting on this since it is not worth arguing with friends over, but if I am wrong the so is the industry's top range finder makers.

Pythagorean [sp] therom, A squared + B squared = c squared. Carpenters use this alot [was one once] aka 3,4,5, or 6,8,10. Here's my tests and results. I have three ladder stands 12' tall, baits for bear at an average of 17 yards from base of tree stands are in, ranges 20 yds w/ rf. Standing up for the shot, I figure my bow is about 17' above ground. Using my 20 yd xhair on a block target,I got dead bear as soon as i can find one dumber than me. Much ado about nothing until you get way high up and start shooting either down hill or up hill. It's the seven "P's" guys, proper prior planning prevents pizz poor performance.

Hopefully no one is getting hot under the collar Hotburn. Also hope you do reply as you bring plenty of info to the table about this topic. I am curious about this subject, and find it to be very interesting. I am always willing to learn more as I hope others are as well.

I am going to do more research into this myself. For me personally its shows if I am using the wrong yardage when taking my shots. This can mean taking a clean kill shot or wounding an animal.

Here is the pythagorean Theorem awshucks is talking about.
I have shot over 200 arrows from my treestand in the past week and a half to 40 yards, can't seem to notice any real difference.

I feel like the caveman on the Tv commercial where the news reporter makes that long explanation about whatever and they ask him if he has a comment and he say "WHAT!!!!!!!" You know the Geico commercial.........

Pydpiper

Yeah, that stuff didn't make much sense to me either..
Thats why I stick with the story that there isn't much of a difference.
