The eTrex Summit was designed for both marine and recreation use. This
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.
The eTrex Summit: It's what the hard-core outdoorsman has been waiting for.
