I wanted to add a note to my already lengthy post about the gps that I use. I always had great luck with waterproofness, even when others were not.
The other day, I received a replacement garmin etrex legend gps from Garmin International. I had sent mine in for water intrusion malfucntions.
The unit that came to me had a new faceplate (as per the workorder attached) On first rinse of water, it imediately took on water under the faceplate. I now see how some people would have called this unit "anything but waterproof."
On a good note however, Garmin has always fixed it for free and given me an additional 3 months of warranty coverage that starts with each repair.
