The last thing GIS users need to worry about is whether the data collected by GPS meets the accuracy requirements of the intended application. So which is better , a recreational gps or a professional gps

A recreational GPS unit is designed to acquire a location fix quickly without the need for pinpoint accuracy because hikers can find their campsite once they get within 10 meters of it.

With budgets tightened everywhere, some GIS users have begun looking at and buying less expensive recreational GPS products that are popular with outdoor enthusiasts. New features, such as ruggedized cases and differential correction, and a price tag often below $500 make recreational GPS units attractive compared with higher-priced professional-grade GPS receivers.

But beware..There is a significant difference in the accuracy of location data acquired by recreational GPS receivers versus the professional units. The 10-meter error typical of a recreational model won't cause a major problem for a hiker in the woods, but such inaccuracy may not be acceptable for GIS applications.
