Get your feet wet in GPS surveying without getting in over your head
The Trimble® R3 GPS system is a complete L1 GPS postprocessed solution from the industry leader in GPS surveying technology. Combining an L1 GPS receiver and antenna, rugged handheld controller, and easy-to-use field and office software, the Trimble R3 system brings precise subcentimeter control to your site, establishes new localized control, and collects topographic data. The system operates without line-of-sight between points, and it can operate day or night in any weather. For the first time, the Trimble R3 system integrates a survey-grade receiver with the popular Trimble® Recon® controller, a proven, ultra-rugged PDA designed especially for tough surveying conditions. The compact and lightweight Trimble R3 system thus handles drops, extreme temperatures, and water with ease, making it one of the toughest L1 GPS solutions available. It also spares you the expense of a separate GPS receiver. The Trimble Recon offers many other innovative features to make your L1 GPS workflow easy and efficient: a large color touchscreen, expandable memory, and USB support to name a few.

Trimble R3 GPS System includes:
Trimble HI tape; Trimble R3 system field case; Trimble R3 pouch; Trimble Recon cap base; Trimble A3 antenna cable ; Tripod bracket.
