I'm looking for a handheld GPS unit. Will be mainly used for hiking and biking. I want it to be able to track longitude and latitude. Should be able to mark areas in open land and water. For instance, let's say I'm fishing out in the ocean, want to be able to mark that point, or if I'm on a hike in the middle of nowhere and I want to mark that spot for whatever reason.
I've seen a few that can be used with your mobile, but they seem to be more like a gps you'd use in your car. Not really looking for something that will give me street directions. Have that already for my car.
Anyone use these? Can you recommend one?
