This is a weatherproof 8 channel GPS receiver. It is too old to support WAAS correction so positional accuracy is approximately 5-10m. The Garmin 40 can store 250 waypoints and 20 routes. The unit requires four AA batteries and claims to run 20 hours on alkaline batteries. Weight: 9.5 oz with batteries.

With the use of the ARF's Garmin PC interface cable (RS232 serial port connector) you may download the points to ArcGIS.

The Arcview / Arcmap toolbar DNR Garmin Application: Minnesota DNR makes downloading Garmin data into ArcGIS easy.
