Great GPS for under a $100. Does everything I need.


  • Price
  • Already preloaded with all maps
  • Geocaching??
  • Fast
  • Loop around feature


  • No belt clip
  • Paperless geocaching not compatible at this time.

I bought this for around $85 shipped from Amazon for rattlesnake hunting the mountains of Western Pennsylvania, geocaching, and for hiking with my wife and daughter.

With all honesty, I've only had one other GPS and it was a Magellan Sport I found it to be worthless. So I have nothing else to compare it to.

This thing is very easy to use. It picks up satellites very quickly. It is loaded with maps for trails, forests, and bike trails, etc. It is very durable and waterproof. It comes with a handlebar mount for a bike, which I haven't used but seems pretty nice. I definitely wish it came with a belt clip though for hikers.

It uses two AA standard, or rechargeable batteries which seem to hold up pretty good. So far we've only used it trail walking and it got us back to the truck safely. I would buy this again. Love it.


After further review, a few things I'd like to add are, I found that at times it's confusing to start and end trips when moving from one place to another.

For example: While snake hunting new areas, I would set a waypoint at the truck and we'd hunt a certain area, venture back to the truck and try to end trip and then drive to the next area, try to set a waypoint at truck and it would say tracking resumed and not set a waypoint. It would show a line to the last area I was at. Couldn't quite figure it out. Ended up using it like a compass and using bodies of water as landmarks to get back to the truck.

It's probably my inexperience that's the problem, but it can be nerve racking.

Also, it came with built-in paperless geocaching, but isn't compatible with geocaching.com at this time. Huh, go figure. They give you one month free premium on the site, but a huge part of the GPS's programming isn't compatible. Have to enter coordinates the old way, which is a little misleading when purchasing.
