I have been shooting my 7STW pretty comfortably out to 700yds. I want to stretch it out to 1000yds now. I have been using a very basic ballistic program and I would like advise on the equipment needed. I am thinking of the Kestrel 3500, NF xbal and I have no clue on a PDA. It needs to be basic. My current cell phone is just that, a phone. I have limited computer skills. In addition, I have signed up for one of Shawn Carlocks basic classes and I would like to be proficient with it by June when I take the class. Any suggestions would be appreciated. Thanks.
