Help a fellow rider keep track of (and share!) those great trail routes and campsites with the Trackstick II, a device that uses global positioning system (GPS) technology to precisely record one’s travels, down to stop times and speed. Download to a Windows XP-compatible computer and Google Earth, and your route is translated onto satellite-based maps and as three-dimensional geographical terrain. The Trackstick II GPS runs on NiMH or AAA batteries; its one-megabyte flash memory can hold months of location histories. The device comes with a weatherproof case, a detachable belt clip, and an integrated USB 2.0 connector.

Cost: $179.
