I am just kinda getting started on shooting long range. I have a Sendero in 7mm Rem Mag. I am working on getting a range finder(never used one before, but never tried shots that I would have needed them for), and am looking at wind meters also. My buddy tells me the Kestrel's are pretty good. I am wondering, with all the different models and capabilities out there, waht do I really need? I am thinking the 2500 with Wind, Temp, and Barometric Pressure would be pretty nice. My question would be do I really need the BP? I will be shooting strictly long range hunting, no target. Thanks for your help.
