Entry level 12 channel GPS. Bigger than the newer "Geko" model. The basic (yellow) model has no base map at all. Runs on a pair of AA batteries. There is an API for the serial port which can be used to download the trace record. An early version of the DNR Garmin Application http://www.dnr.state.mn.us/mis/gis/tools/arcview/extensions/DNRGarmin/DNRGarmin.html supported this API which made it easier to download the trace info as a CSV file or to convert it to an ESRI compatible .SHP file.

- One-handed use.
- Suitably splashproof.
- Very widespread, so well-supported for accessories (e.g. bike mount).
- Not possible to upload (OSM)-map
- No memory card slot, smallish memory. Cycling fills the track log at around 110km, after which the earlier parts of the log are overwritten. So complete mapping of rides above 110km is not possible.
- The user has no control over the sampling interval on early models (firmware 2.x) at which it records tracklogs to its memory.
- This is not quite the whole story. The early etrex doesn't have a preset "sampling interval" like (say) a Magellan. Instead, it uses an algorithm that samples more frequently when turning corners, less frequently when running in a straight line. This enables it to record much longer distances than might otherwise be expected of its (fairly low) 1500-point memory on early models (firmware 2.x). As an example, it is just about abl
