I'd be more concerned with accuracy than ruggedness. I've charted my photo locations at Grandfather Mountain over the years, upgrading GPS receivers along the way: The number of channels, WAAS capability, etc. have improved with each iteration. I record my coordinates in UTM format, so it's been easy to see the big improvement in accuracy along the way (some of the measurements I made with my first unit would vary by over 100 meters the next time I visited the same spot); the time required to initially lock on to satellites and to stabilize at a specific location has been drastically reduced. Of course, this is moot if your GPS gives you the accuracy you *need*. At GFM a 10 meter discrepency can be the difference between getting a nice view or no view at all or plunging off a cliff to your death. If you just need to know that a shot was taken in Lexington, Kentucky or Portland, Maine I'd think any GPS would do ;-) -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
