thank you- I agreen on only uploading from one computer but was wondering how they would show up- I bought both during the winter and after this horrible winter in Northeast just dying to get back in water and try them out...@pconsidine they show up by their serial number so if you name them the same, they'll overlap, but if you have the same dive profiles, i'd just upload one of them to the log personally. no sense in having double dives in there imo
