[QUOTE="lboom, post: 1011870, member: 13237"] For every 1000 foot of elevation you go up you lose 1 inch of barometric pressure. When inputing data in programs the barometric pressure you get from local reporting is corrected to sea level. Therefore the actual pressure at the altitude you are hunting at is barometric pressure minus (altitude divided by 1000). so an example if the local pressure is 30.00 and you are hunting at 7500 ft then the actual pressure is 30.00 minus 7.5 or 22.5 [/QUOTE]
