I have a 16' ladder stand that I always practice from in the backyard. This way my pins are set up for game time (meaning a hunting situation), not practice time. Iput outa block target or two and use my range finder just as I would in the woods. I personally feel like it's a way to remove one more variableI would haveadjust for when tension is running high, and I've had great success since doing so.

What you're talking about is also the theory behind penudlum sights I believe. The mechanics of the sight compensate A^2 + B^2 = C^2

Just as Wis Bo Huntr said, you need to aim a little lower when shooting from a tree with a bow that is sighted in on the ground. How much or how little depends on the setup, your height above ground, your target's distance away, etc. By sighting in from a tree, and practicing from a tree, all I need to do is worry about my yardage, not my yardage, and then remember to aim a little low... no, no, no, still a little lower.... sh*

One of the main reasons for having to aim lower shooting down hill or up hill is the gravitational pull--Shooting down or up less pull from gravity!!!IMO!!!

There is a difference in "Point of impact" from the ground to 20 feet up a tree.

For my bow @ 260FPS the difference is about 1 1/2" @ 27 yds.

Seems to me the actual difference - line of sight distance is some where around 2.5 yds. @ 30 yds.

I myself don't think it makes that much difference in real world hunting situations,BUT, if you know about it you might as well adjust your sights for it.

IMHO

I always practice from a tree before season opens but never notice a difference in my shooting.

It depends on the speed or droppage of your arrow, the height of the stand and how far the target is. To know how much tocompensate (now you have your triangle).The easy way to compensate would be to use your range finder and target a tree near your intended target measure your distance the same height up as your are in the stand and go with that distance.

It uses more than just the pythagorean the theorem.It compensates for arc as well I believe.Which makes it a great product for hunting mountains.


The problem is that from hunting stand heigts,all this is way over rated.The biggest difference in a triangle is when the angle is increased,meaning,you have to be shooting very close to straight down for it to take effect.The problem with that is that the distance from your stand is so close it probably doesn't matter anyway.



When you increase the distance from the stand,the angle flattens out dramatically so very little compensation,IF ANY is needed.

DITTO!!

When I'm hunting from a stand, I will range an object directly in my line of sight, at the height I'm at. Subtract 2 yards, set my sight, and I'm dead on.

Bend at the waist, pick a hair and give it to em.

23 yards from the tree is 23 yards from the tree...the difference in a range finder and the pythagorean theory is what, (we had the chart here some time ago), less than a yard, two at the most depending on extreme heights....in a hunting situation you can't shoot the difference, worst case, pick a hair under the hair you were going to shoot and remember to aim for the exit hole.
