The simplest way to see the differences is to set a target up in a plcae that you can shhot at it from ground level and an eleavated stand using the same pin. I use my back porch for this as it is much easier then climbing in and out of a tree stand.

If you want to test it mathematically you can set up a spreadsheet using simple Physic equations and see what the differences would be. Knowing the math will help you fully undertand the shot and should make you more confidant. I will consider posting more if i get the time to look into it more.
Good suggestion. Practice from an elevated position is a good thing to do. And it's geometry, pathagorean therom I believe. Physics would be for the other can of worms I was talking about

it makes a huge difference. not only is it closer but the broad side 8" kill circle becomes a 3 by 8 kill oval. if you know what i mean. even with todays speed bows

I always love this discussion. The bottom line is that gravity pulls on the horizontal plane not the vertical, the easy fix is to range on something that is the same elevation as you are shooting from. Check the ranges to a point up the tree instead of the base. I usually check a few trees at first light then adjust accordingly to where the deer is standing.

SM, something else, in Bruce's example the hunter is only 12' up the tree, when your 20 or 25' up it makes even more difference. When you consider there could also be a change in elevation from your stand to the deer the difference could be dramatic, what reads 25 yards could actually shoot 18.

Buckshot it's Actually the opposite, the higher you climb the further (not closer) the shot becomes but what does change is the kill zone,
it becomes a smaller diameter and more of a vertical shape oval.

i'm with buckshot the closer, the shorter pin, it becomes. it ranges further but shoot like its even closer. if the deer is "broad side" and you're way up the elevation of the kill is shorter but the widage stays the same.

I agree too with "Closer the shorter pin" but his example was a deer at 25 yards he said it might be an 18 yard shot,
that would put him up the tree about (15 yards) 45 feet high....

or 45 ft above the target. i've seen it up the tree 25 ft and 20 yards out from the base of the tree down hill another 20 feet. thats a 1 in 3 slope very flat for here and in vt

Bruce I was adding in the extra elavation if the deer was down hill. It was really more of an example based on some bad shots I have made in years past than in the actual math. It was years before I understood what had happened to me. I think it is great that this thread may save somebody else the same fate.

The bottom line is range from point to point at the same elevation your stand is at and you don't need the trickynomitry reguardless of the angles.

So, the question is, Will the angle compensation rangefinders solve the problem?

come buckshot there ain't no hills in east tn. grin

take that a,b,c, diagram, mirror it and flip it upside down to account for the hill. conversely if the target were up the hill and in range,,,,,,your stand is to low. grin
