i have a kestrel 5700 elite ab, sn#2160498. i have down loaded the latest firmware. i have had it for years, i used to be really into the precision rifle stuff. i bought the weather vane for it, etc. but it has always given me problems. but i think i am onto something finally. i've been getting ready for an elk hunt so i've been playing with 5 guns, Defensive edge 338 ai terminater, a kirby allen 338 ai raptor, 2 different GAP built 6.5 saums, and a Coffin custom 7mm rem mag. all very nice guns. as i was getting re-aquainted with them and trying different ammo, i noticed a pattern that using the kestrel
they were all shooting low, .1-.2 mils in the 400-500 yd range, and also shooting low out to 900 yds. finally yesterday, a local dedicated shooter let me borrow his similiar kestrel at the range. i downloaded 3 of my profiles, 6.5 saum, 338 raptor, and 7mm onto his kestrel. i then compared them side by side with the exact same profile. ignoring the wind calls, ( i didn't make the wind the same, only the target distance and direction (395 yds, and 175 deg) as you can see from the pics, his kestrel always had about a .1 mil higher solution,, i also compared all the weather numbers. our weather numbers were kinda close but no where near exactly the same, there has to be some input that is acting on all my profiles to make them shoot low. the weather numbers didn't match but they were close,,, i don't know how important all the weather numbers need to be. pics to follow. mine is the tan one
it has always done this and i usually do a profile calibration with the mv, but i have a nice labradar so i know my ave mv. and it is decent ammo so pretty low es and sd

any thoughts? i am cross posting this

250 degrees would be like 830 o'clock wind. So opposite wind directions and opposing AJ corrections would add most of that .1 mil difference. The Ballistics menu will tell you exactly what the solver is doing to get the total solution.
 
I have 2 Kestrel Elite 5700s that are identical other than color. I noticed one day that both gave me different solutions for a 1-mile target, and I could not find any settings different. Ultimately, I discovered they were calculating slightly different environmental data, and I had to tickle or nudge one or more environment setting (like temperature, altitude, etc.) and that forced them to recalculate the environmental data and now the shooting solutions where the same. This was a couple of years ago so I don't have the specifics, but it did demonstrate the units sometimes can have different firing solutions with what appears to be the same input variables. So, I'm not surprised by your findings, but I don't know specifically what is causing the difference in your case. I suspect however if you could have adjusted both units to the same environmental variables, you would have seen identical firing solutions.

Op has different input variables though.
 
update: i believe i have figured out why the kestrels were giving different solutions. now i am back to trying to figure out why all kestrel solutions are too low. i am going to play with some of the inputs again and see what happens,
