Comment: Types of GPS Receivers

I'm a big fan of GPS used in combination with paper maps for camping and 4WDing. I recently bought a Garmin eTrex 20 handheld device, and purchased the Topo Maps and Birdseye Satellite imagery (subscription) all for about $250. Great unit albeit the screen is a little small. But it is great for marking waypoints (handy for marking future camping spots) but also laying breadcrumbs (so you can find your way back to basecamp when you're trekking deep in the wilderness) and providing info (like sunrise/sunset, best fishing times etc). USB connectivity to your PC to send and receive info to and from the unit using the Garmin Basecamp software (free download). It will never replace the good old fashioned paper maps, but handy to have nonetheless. Only downside is it chews through the batteries, so carrying extra batteries is a must (and a pain).
