An outdoor adventure retailer or nautical store would be a good place to start looking. Also there are GPS mods for palm pilots and some cell phones. Aviators use hand held GPS for gliding.
If you're just looking for a very rough approximation of your site, a handheld GPS might be all you need. Proper surveying units are not cheap, starting well into the thousands of dollars.
By 'rough approximation,' that means about within 15 feet of accuracy for most mapping handhelds. For a unit that's accurate to less than a meter / 3 feet, you're looking at about $3000+, give or take.
You might be able to rent something. Anything on a palm pilot or cell phone is going to be totally useless.

we tried to map the topo of an urban site with handheld GPS units two years ago, ant that +/- 15 ft accuracy made it totally impossible. At one point, I had a measurement from on a bridge that I knew was 28ft tall, and the one on the bridge registered as 6 ft below the one off of the bridge.
gps survey equipment??
can some one recommend a gps surveying tool that is inexpensive and easy to use. i just need to plot the points of a strange shaped site. thanks!

maybe you can rent the equipment or see if a dealer will allow you to test the stuff for a few days before deciding not to buy...

can i get a GPS accurate enough to do as built measurements?
