My GPS Units

The two GPS units that I use are a Garmin eTrex and a Garmin GPSmap 176. The eTrex is the unit that I use in the field. It’s a great rugged GPS unit that can take a licking and keep in ticking. I bought a USB interface for it so I can connect it to my PC and download cache’s straight to my GPS unit. The other unit that I use is a Garmin GPSmap 176. I original bought this unit to use as a chart plotter for marine navigation to use while I was sailing. It worked great on the coast detailing island and the cost line and such. When I got into Geocaching I bought Garmin Mapsource North America and a memory card and converted my chart plotter into an on road navigation system.
