I am using the older 1600 , I have not gotten far enough into the program far enough to pass an accurate assessment, but lets just say it probably will be of little use to me as I use my phone app too ( Applied Ballistics)
Not I have been looking at the intfo it supplies, baro, temp and shot angle. That might be of use at some point, but for now still using the Kestrel.
In the past week I have been doing a little testing of just the ranging ability of this unit. I have ranged a tree just before dark at 1957, haybales mid day at 1600 + and the other day I was ranging a herd of whitetails over a FLAT snow covered field. It would bang on every deer instantly. The farthest was only 700 yards but it did a great job. I used my Vectronix to proof test as I trust it 100%.
