I use the TDS Recon in my surveying business. It is one tough computer, its been dropped in a creek, ran over with atv and its still running. TDS has upgrades posted regularly on their website. I have been using the same Recon for 6-8 years and thats a lifetime on a survey crew. That being said, I have not used it for ext. ballistics. I use a palm for ballistics program but have been debating upgrading software to windowsCE model for recon. Hope this helps. Wade
Never argue with an idiot, they will drag you down to their level and beat with experience every time.
