Ok heres the way I have been told by oldtimers years ago. I still use this today. For every 3ft I climb in a tree you add 1 yard to your shot. So if your 15ft in a tree you should add 5 yards to your shot. You never shoot low if you use that formula. Some may say Im nuts but give it a try. Works for me...
????? No way I'd use that either. The pythagorean theorem is how to figure it out. It ends up being negligible because most guys are 5 to 6 YARDS up in the tree and shooting at deer 20 or 25 YARDS away (remember to use the same units!).
For example if you are18 feet up in the airand the deer is 75 feet (25 yds) away from the base of your tree, the actual distance is 25.7 yards instead of 25. That's nothing.
That's why pendulum sights are a bunch of BS in my opnion.
