With its sturdy, dark-gray case, the Geko 301 packs an amazing amount of functions into its slim frame. It has all the features of the Geko 301, 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 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.
