what Badger isreferring to is the pythagorean theorem correct.

Asquared plus B squared is C squared (sorry, not proper format)

A= distance from tree to target on ground
b=height of your tree stand
c= distance from treestand to target on ground.

Say a=15 ft, b=15 ft

a squared=225
b squared=225
c squared=225+225
csquared is 250
c=21.21 feet.
Basic math, there is a difference! I justneverdid the math to find out how much!
