GPS devices used for data collection are not the same as GPS devices used for navigation.  We recommend and support GPS devices that will coordinate data collection through ArcPad and/or ArcGIS for data collection in the field. 

The following GPS devices in the table below are currently sold directly and supported by AgTerra (April 2009).  Select a device based upon the features that suit your needs and contact AgTerra to order your device.  AgTerra will install ArcPad (if applicable), and your custom map data no additional cost if the device is ordered through our company.  Click on the device name to download details from the manufacturer.
