I'm in the market for a hand held and ballistic computer to assist my LRK. I have searched and read many of the post about this topic but still not sure which one to pick. Many of the posts were a year or two old and there might be something newer out there. Is upgrading to a "smart" phone worth it? Or should I go with a PDA/pocket PC and the Nightforce program? Has anyone used the Mobile Ballistics Solution sold in the Gear Shop? I'm looking for something that just flat out works, no matter the conditions. It will also need to be tough, Marines aren't known for being careful with equipment. Thanks for any info and opinions.
