I'm not sure if this would be a good choice though (and I like Magellans) since it appears as though there is only 8 MB of memory and you can't expand the memory. It also doesn't float, but the real issue for would-be geocachers is that (if I'm reading the specs right at the Magellan site) that you can't input waypoints (data input). Too bad though since I often think it would be nice to have a second GPSr to compare coords.
