Lets say you are 10 yards up in a tree. The range finder selects a deer that is 20 yards away. I am not sure what the the exact distance is but let us say that from the base of the tree to the deer it is only 15 yards. From 10 yards up in the air do you aim for the 20 yards what the range finder is showing or the 15 yards which is the actual distance from the base of the tree to the deer. Should I aim for 15 or 20? Need help on this. My physics and trig are a little rusty.
Thanks,
Also with a name Vector this looks very bad. Vector was the name of the boat I had not that I remeber my physics or trig..
