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.

The eTrex Summit: It's what the hard-core outdoorsman has been waiting for.

The main differences between the eTrex and eTrex Summit

• The eTrex Summit has an accurate pressure-altimeter which records the altitude (in one foot increments) at waypoints.
• The eTrex Summit has an electronic compass. Other GPSs can only display compass direction when you're moving.
• eTrex Summit records 3000 tracklog points. eTrex, and almost all other GPSs record 2000 points or less.
