I dont get it if I am sitting in a ground blind and my range finder says my target is 27 yards then that is what it . If I am sitting in a tree stand 30 feet in the air and I range my target with a normal laser range finder and it says 27 yards then its 27 yards! How do people fall for the arc technology range finders ? Or am I not getting something?

you're not getting something... because you are shooting uphill or downhill, gravity's
effect on the bullet or arrow shaft is slightly different... draw a 90 degree triangle by
drawing a capital L on a sheet of paper.... if you are at the top of the L , and your
target is at the bottom of the L, and you draw a straight line from you to the deer and
measure that distance... it is greater than the distance from the bottom of the L to the
target... but gravity's effect is equivalent to the shorter distance, not the longer distance
from you to the target.. hope that makes some sense

using a shorter "straight" line distance, as opposed to the "true" distance
from the shooter to his target... you'd have to understand or calculate
gravity 9.8 meters/second (squared) and it's effect on an object fired
at a 90 degree or horizontal target line, and it's effect on an object
fired at say an object +/- 45 degrees from horizontal... but the
straight line is easier to picture or understand..

I have one, and for most of my bowhunting, the arc distance is within a yard of
the straight line distance out to about 30-35 yards... probably works better
on longer rifle shots up or down hill...
So like I thought it dosnt make a differance out of a tree at 20 -30 yard shot with a 450 grain Easton FMJ shot form a Mathews Z7 at 289 feet per sec.

are all around 15ft or less... so unless the animal is right underneath
me... I use my 20yd pin from 15-30 yards... and I'm shooting 450 fmj
also, at 282
