Fred Theilig of Rhode Hikes would not buy the minimalist Bushnell BackTrack GPS.
For only a few dollars more — $89.00 right now on Amazon — he’d recommend a Garmin eTrex. This one is waterproof. And gets up to 17hrs on 2AA batteries. Editors of Trailspotting and Take a Load Off agree.
Many are confused by GPS feature sets. (Including me.) We might want to buy a Garmin GPS Etrex Instructional Video at the same time.

Though I’d definitely recommend the eTrex over the BackTrack, I’d also recommend you consider the Garmin eTrex Venture HC.
They’re $130 on Amazon at the moment but I’ve also seen them for sale at $110 too (try pricegrabber.com).
For the extra cash you get:
– a MUCH better color screen
– USB connection (simpler than serial)
– a basemap (shows roads & major features)
– ability to add maps (I have articles on how to download free maps, but this can get a bit tricky)
Here’s a link to Garmin where they compare the products

I’ll back up my recommendation later this week with a Trailspotting article to show how easy it is to use the eTrex Venture. In the interim, here’s a link to my GPS introductory article if it’s of any interest ..

Okay, as promised .. I’ve posted an article called ‘First Steps to your new GPS’ based on the eTrex Venture HC. Maybe I can upsell you on the Venture yet, Rick!

A good friend gave me an eTrex, and I use it extensively, never finding a good enough reason to upgrade. The only limitation I run up against is that it only has enough tracklog storage for about 22 miles of hiking, which is sometimes less than a day for me. The serial connection adds steps to interfacing with a PC, but I have the procedure down. It’s one of those rare bits of technology that just hit a sweet spot.
I agree, the etrex H version is greate but Check it out here. http://gpsforhiking.buycheapshoponline.com/garmin-etrex-legend-hcx-personal-navigator/
Its a HXc which is a lot better.
but if you looking for the cheaper one try etrex HX version it works great but no SD-Card slot if i’m not wrong. Here is the detail http://gpsforhiking.buycheapshoponline.com/garmin-etrex-legend-hcx-personal-navigator/ this one you will save for 60bucks compare to HXc version.
