Love it for Sailing!
By M. Keough
I got my Garmin 78sc a couple of weeks ago, to use not only on the water (Chesapeake Bay), but for hiking and geocaching. By now I've sailed for 3 days,(about 15 hours total run-time), and the alkaline batteries are with regards to half gone according to the meter, so I'm reasonably satisfied with the battery life. I haven't tried NiMH rechargeables yet.

OMG This thing is awesome!
By Russell L. Watts
I've owned assorted handheld GPS over the years. This thing finds satellite's and locks in regarding 10 seconds......in my house. My other handheld which was likewise a garmin would only find satellites outside only on a clear day when no trees were within sight. OK I'm exagerating. There could be one or two trees near but not too near. This 78sc sreen is amazing also. You may see it from any angle, in the sun, with sunglasses on. I LOVE THIS THING. It's simple to use. I'd buy it again. If any person gives negative feedback on this thing they are in need of help. Serious help.
