i have been reading post on here for awhile and alot of you guys say that you should have a pda with your program in it. i am wondering what pda seems to work the best and what programs are the most accurate. right now i have my data taped to my gun. i now travel for work and carry a varmite gun with me at all time, so i think that a pda would work better. also do you know if exbal can be put in a pda. this is the program that i use.
