Hi Everyone, I'm a geo-spatial data analyst in the real world; after hours I'm interested in & (am) building small wooden boats & navigating them to interesting nearshore places......creating trip plans on my Garmin eTrex 20 handheld gps with marine charts installed & logging the trip in progress. I also have a Holux M-241 which is great for tracklogging but does not have the realtime GUI that the handhelds do. Still learning but happy to share what knowledge I have.

best regards
