Garmin GPSMAP 78sc 2.6-Inch Waterproof Marine GPS and Chartplotter - Featuring a bright 2.6-Inch LCD color display with built-in basemap and
high-sensitivity GPS receiver, the GPSMAP 78 series takes recreational
navigation to a whole new level. All three models are waterproof, and
include a built-in microSD card slot for loading additional maps and a
dedicated MOB (man over board) button.
I was concerned the unit was going to be huge (it's intentionally large to give internal air space for water flotation ability), but it's not too big or heavy. It was smaller than I was expecting it to be. Also, having the buttons on top of the screen are a little weird, but it's not a big issue in use. It's very fast in finding the satellites and switching display screens, etc. The built in electronic compass (multi-axis)calibrates quickly, and reacts quickly to movement, but seems very accurate. There is an option to have the map orient to either the compass heading (direction you point the GPS) or from the track (direction you were moving in is oriented "up").
Garmin GPSMAP 78sc 2.6-Inch Waterproof Marine GPS and Chartplotter Reviews
I got my Garmin 78sc in 2010, to use not only on the water (Chesapeake Bay), but for hiking and geocaching. By now (2010) I've sailed for 3 days,(about 15 hours total run-time), and the alkaline batteries are about half gone according to the meter, so I'm fairly satisfied with the battery life. I haven't tried NiMH rechargeables yet.I was concerned the unit was going to be huge (it's intentionally large to give internal air space for water flotation ability), but it's not too big or heavy.
