Garmin GPSMAP 78 Series
Garmin released a new line of handheld GPS devices today aimed at marine use. The Garmin GPSMAP 78 for $350, the Garmin GPSMAP 78s for $450, and the Garmin GPSMAP 78sc for $550.
The new devices feature rubber side grips that make it easier keep a hand on while out on the water. The GPSMAP 78s and 78sc devices add a 3-axis Electronic Compass which means the compass will be relatively accurate in any orientation.
Each device comes with a transflective 65k color display, and feature a case/weight combination that floats. The new models also support wireless data exchange with other Garmin wireless devices.
You can expect to get about 20 hours of run time from two AA batteries. Satellite acquisition should be quick… both because you’re out in the open on a boat and because these models use HotFix for fast satellite acquisition.
Memory includes a microSD card slot and 1.7GB of onboard memory. All three models include a built-in worldwide basemap while the 78sc also adds Garmin Bluechart g2 maps for the US coast. All maps also support Garmin’s new Custom Maps and Garmin BirdsEye satellite images. These models are expected to be available in May.
