Compare Garmin eTrex Summit Handheld GPS Receiver to Garmin GPSMAP-76S Handheld GPS Receiver

The eTrex Summit comes on the heels of the extremely popular eTrex, which was designed for both marine and recreation use. This new all-in-one navigation device for the outdoor enthusiast is the first combination GPS, altimeter, and electronic compass. The electronic compass provides bearing information when you're standing still and the altimeter determines precise altitude, so you can tell how high you've climbed and your rate of ascent. Like its predecessor, the eTrex Summit boasts a powerful 12 parallel channel GPS receiver and comes packaged in a small, sleek case with operating buttons located on either side of the unit. The case is completely waterproof to withstand immersion in one meter of water for up to 30 minutes. Less

The GPSMAP 76S is preloaded with a basemap of principle cities and roads as well as marine navigation aids, including lights, buoys, sound signals and day beacons. It also has 24 MB of internal memory, so you can load detailed maps from a variety of optional MapSource® products. If you're into boating or fishing, you can use the built-in celestial data, which includes tide information, sunrise/sunset times and a hunting and fishing calendar. Less
