Very nice and all I need. No computer on board. No chartplotter, other than the basic route screen on the 76, following a black line with no map on it. No PC on board. Works great. See you out there.
EasyGPS is great and it also easy to enter waypoints directly into the EasyGPS screen if you are not using OpenCPN or similar. But do make sure you are using the same degrees/minutes settings on EasyGPS and Garmin. My Garmin defaulted to hddd mm.mmm (which I prefer) while EasyGPS defaulted to hddd mm ss.s
I entered hddd mm.mmm waypoints into hddd mm ss.s fields and, once I realized, I had to change the setting in EasyGPS and then enter them all again (couldn't find an easy way to convert). I'm glad I decided to check them against the chart before I set out.
