Measuring with GPS

Do any of you use a GPS to measure your lawns? I used one today to measure a 4 acre property. It worked great. It was a cheap one that measured feet. Does anyone use the ones that measure the sq feet? I did a search and read all the post but would like some current feed back. I am also interested in connecting it to my Palm zire 71 for mapping. What mapping program would someone recommend?

 

What a great idea...as long as it is truly accurate.

 

I use a Garmin etrex venture. I have been measurign yards with both the gps and a measuring wheel. It has been very accurates. Use it on yards as smalla s 5k.

Bought it for 120.00 on ebay

 

Hamons:

Will it calculate sq. feet? The one I was using,
