Gekos are the smallest and lightest waterproof GPS units on the market—inexpensive, with sleek designs and simple operating systems.

With its sturdy, dark-gray case, the Garmin Geko 301 packs an amazing amount of functions into its slim frame. It has all the features of the Garmin Geko 201, plus an electronic compass and a barometric altimeter. The compass provides bearing information while you're standing still, and the altimeter determines your precise altitude and provides a 12-hour pressure-trend tool for gauging changing weather conditions.

The Garmin Geko 301 also includes five interactive games that transform the great outdoors into a virtual board game, including the new Gekoids, which takes advantage of the electronic compass. You can also enjoy a good workout while chasing a virtual lizard in Geko Smak, match symbols in a grid version of Memory Race, navigate to reference points without crossing one’s trail in Nibbons, and collect symbols along a path in Virtua Maze.
