kestrel elite 5700 ab problems, what am i doing wrong

[rockwind]

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

I would wipe your kestrel, do any updates and start fresh, build a new profile. Don't upload that old one.
See where that gets you

Do you use any ballistic apps as well as the kestrel? Reason I'm asking as I use a Hornady ballistic app in conjunction with my 5700 elite, they both match up unless I input something wrong into one, the other will show me something is off. Case in point, at the range a few weeks ago I was shooting steel and had to put a 21 degree input into the Hornady, can't do that with the kestrel but never reset it back to 0 when done. A week later I went out to the desert to shoot out to 700 yards, I used the Hornady calculator first and didn't even hit the target. This rifle always makes that shot so I cross checked it with my kestrel, they didn't match up, it took a few moments but I finally figured out what was up and corrected the Hornady app, I was back in the black after that. Sooo, it doesn't take but a minor input error to make an electronic device spit out bad information, it helps to have another to cross check.

You should be able to put angle into kestrel

Haven't figured that one out yet
