The Garmin eTrex series is extremely popular among OSM users and generally gives good value for its money. A lot has been written about the different devices in this series, so we were forced to move some of the descriptions to individual pages.
The eTrex, eTrex Venture, eTrex Legend, eTrex Summit and eTrex Vista make up this range. Colour models have a "C" after their name, and those with an "x" can take expansion memory models - good for OSM maps and Long journeys. Some of the older black & white models are capable of displaying maps although memory is limited to 1MB on the Venture, 8MB on the Legend and 24MB on the vista. Some of the higher end models (eg: Vista, Vista C and Vista Cx) have magnetic compass and altimeter.
Since the summer of 2007, there's a new range of "high sensitivity" receivers, coded with "H".
Discontinued models can be found here.
