Garmin GPSMAP 78sc Waterproof Marine GPS and Chartplotter

We have analyzed 184 reviews and found:

24% of users say that: Product worked great, was smaller, has all the marine functions, has "anchor drag" alarms. Unit was flipped 180 deg, is great, is sturdy, can do everything. Screen is great, is better than previous models, is better, is easy to see. Gps is excellent, is reall a good product, is important with rocks and fog, is good. 3% of users noticed that: Garmin get your stuff together, will not buy, has replaced the units. Batteries come close to dying, were down to 1 of 4 bars. Buttons on top of the screen are a little weird. Battery compartment is not waterproof, is not.
