NEW FEATURES ADDED IN 2012 - The SC 900 meter now includes the brand new 3/4" cone tip, as well as improved handling of insertion errors. The 3/4" tip is appropriate for coarse soils. These new features took effect with units shipped after January 1, 2012. Meters acquired prior to 2012 can be upgraded by purchasing the SC900 Upgrade Package (Item #6110FSUP, see purchase table above). The upgrade includes a microcontroller chip with updated firmware, a 3/4" cone tip, new depth target, and updated User's Manual. 


GPS Recommendation: Garmin GPS 73 Handheld GPS Navigator

The GPS 73 is a low-cost solution designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS). The GPS 73 can provide position accuracy to less than three meters when receiving WAAS corrections. This rugged, waterproof, unsinkable GPS receiver offers a large, 4-level grayscale screen. It's designed as the next generation in basic, entry-level Garmin GPS.

* GPS interface requires two cables. The GPS/DGPS cable (Item 2950CV5) is available from Spectrum. A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required.

** PC cable connects to a computer USB port
