gps
 

You can find the hand held gps units at your local best buy, circuit city, outdoor store - or online - just search handheld gps units - I have the etrex vista handheld - works just fine...

You should be able to get one at any outdoor sporting goods store or online. You can also get them through Amazon.com

I have a Garmin eTrex. This one's great because it's fairly small, light, and inexpensive. Amazon has the eTrex for $87.13. [Insert disclaimer about not being associated with Amazon, this is for you information only, no endorsement, blah blah blah]

Get the Garmin Gecko - smaller and easier to strap on to smaller vehicles like TCs and buggies. Works as well as my Etrex (got both).

Thanks a whole lot for the info guys.
