Query: SportTrak a great tool , at a great price!

This is my first GPS but I did some research before spending the money. The SportTrak is compact and lightweight,has a long battery life and is surprisingly accurate. We take it traveling to see distance,path we took,speed we are driving, where the next city is... and Geocaching! A great family hiking, hunting activity where the GPS comes in handy for the cache. The screen is easy to read and understand. It has a back light for nighttime use. We have had ours for two weeks and are truly glad we picked this SportTrak unit.
