[QUOTE="kcebcj, post: 1084442, member: 10391"] For what it's worth I have found the EHR that the 1600B put's out is incorrect. I don't know if it's because it's tied to one of the ballistic curves or what. Getting the EHR from the Line Of Site Range is pretty simple when the angle is known. When I first got the thing and set it up using a on board ballistic curve that was close (but not) to my rifles actual curve, I just wanted to get the EHR to enter into my ballistic program. I started noticing it was not working well when I entered the info into Shooter. So here at my ranch I have a lot of and places to use the range finder from moderate to steep angles out to about 2000 yards. I do Architectural Design work so I started taking the Line Of Site Range into Auto Cad and using the true angle verified by two different range finders would layout the EHR and check it against the EHR the 1600 would put forth. Tested at different angles and distances for a few days and they never jived....not once Also when you take the EHR from the 1600 and enter that number into a ballistics program like Shooter it again calculates the temp pressure and all that stuff really screwing things up. So now I just get the Line Of Site Range, Barometric Pressure and the angle with the 1600B and enter that info only into Shooter and it has worked very well. Now if there is a pre-loaded ballistic curve in the 1600 that matches your rifle really close things might work OK for you.....good luck. [/QUOTE]
