My wife and i have a hobby called Geocaching and our Garmin Geko 201 is invaluable to us. Our hobby involves downloading co-ordinates to the PC, which we can then transfer to the Garmin via a serial cable. You can of course input them manually.
My advice is to read the manual carefully as it may not be the most obvious piece of kit to use. (isn't that what manuals are for? ) Once you get used to it it is a very simple unit to use.
It is rugged, waterproof and has a good battery life. I believe it is even possible to link to some mobile phones such as Smartphones but i have not tried?
It has a breadcrumb feature so that you can retrace your step, current speed, average speed, distance covered and many more useful features that you will find handy, but;
The most important thing is that it is accurate. We have to find objects the size of a 35mm film canister from co-ordinates we are given (plus clues sometimes) and invariably the garmin gets us close.
All in all this is an impressive piece of kit. There are others on the market with more whistles and bells but if you want a good GPS unit for not a lot of money. This is it
