Summary: this is the second one of these I have bought, I liked mine so much I bought one for my son. These are very reliable and easy to use. I can't stress enough the usefullness of a good GPS for hunting!!
Summary: I gave this to my father as a gift to replace one we gave him maybe 10 years ago. The one is leaps and bounds better than the earlier technology. I gave it to him mid july and he walks 3 miles almost every day with the GPS to track his time and path. I visited in Sept and he just wore out the first set of batteries when I was there. AMAZING. The early GPS would only run 20 hours on 4 AA batteries. This one acquires the satelites quickly too.
Summary: It is a bit confusing to use the menu system is odd... But, it works ok and I use it for marking good fishing holes on a lake. Also good for back tracking to the dock after dark. Practice using it before going out in a boat... Excellent for walking in the woods. Love the compass. Be sure to put in fresh batteries before starting trip. In fact, carry some with you... The manual is well written and easy to carry with you with batteries in a zip plastic bag...
Summary: I purchased a used 2006 model Garmin etrex. It works great. A basic field GPS unit for locating points and navigating. Primitive by 2010 GPS standards (black and white, I don't think it has detail map download capability, no base map) it will get you back to camp in unfamiliar country. Don't know where else I could have gotten this much GPS for $23.
Summary: it serves its purpose well. recieved it today and wife and kids went geo caching and found stuff this afternoon. it will also keep me from getting lost this fall hhile hunting in the mountains. it is smaller than my blackberry. runs on two aa batteries so no expensive batteries to find and buy.
