Have experienced similar issues with Subsurface and, until recently, LogTrak. After downloading the latest LogTrak s/w version, past ‘bugs’ seem to have been resolved. No problems downloading dive data from my G2 nor getting LogTrak to recognize my G2. However, getting Subsurface to ’recognize’ my G2 is still problematic. I also use the SSI app but have to manually load data since it won’t currently recognize the G2. Since I dive with other SSI divers, and the club I dive with is SSI-affiliated, makes sense for me to stick with that app. I still maintain a hard-copy log for old-fashioned reasons.
