View your navigation information on any of three graphic screens with a powerful backlight for dim conditions. Other GPS features include 100 waypoints, one reversible route with 10 legs, and a resettable trip odometer that tells you how far you've traveled so you can estimate the time you need to start back. Distance, bearing, heading, direction, steering, speed, time to go, elevation, XTE, time, and satellite elevation are all displayed on the high-resolution LCD screen. Tough rubber armoring protects this unit in the field, and waterproofing allows it to float.

The GPS 310 runs on two AA alkaline batteries for up to 20 hours. It comes with a wrist strap and quick-reference guide. It is covered by a one-year warranty.

BTW, the screen on the 310 and 315 as well as the features are superior to the eTrex basic model, although that model is far more ergonomic.

The Magellan 310 holds 100 waypoints in memory. Higher priced units hold 500, but since I am not a "world traveler" 100 is fine with me. The unit does not come with an NMEA cable to connect to a PC, but Magellan will send you one free if you pay the 5 dollar shipping charge. The owners manual explains all of the features of the unit in sufficient detail that even I can operate it.

The manual is overly pessimistic in regard to the time the unit takes to "fix" a location. The manual says 2 to 5 minutes for a location fix, but I get a "lock" in 30 to 50 seconds most of the time. Sitting on my sofa, in front of a window, the unit obtained a postion fix in 45 seconds with the venetian blinds only partially open. Venturing into a desert canyon the unit performed even faster. With most of the horizon blocked by the canyon walls the 310 locked in a postion fix in 30 seconds.

The 310 also performed well in a moving car, with the unit propped up on top of the dashboard. In the moving car the 310 maintained a lock on enough satellites to register speed of travel and a working "North" arrow.

It doesn't have the bells, whistles, moving maps, etc. of the higher priced units, but it does what I wanted it to do when I bought it.
