For the ultimate in GPS accuracy, combine your GPS navigator with Magellan's DBR IV differential beacon receiver. A compact, all-in-one, beacon receiver and antenna solution, the advanced DBR IV provides precise navigation information for boating, sailing, cruising, fishing or diving. Using signals broadcast from land-based stations (such as the US Coast Guard), the Magellan DBR IV can improve GPS accuracy to better than 3 meters.
This rugged, weatherproof unit connects to most Magellan units or any other GPS receiver that accepts standard DGPS RTCM SC-104 data input. The DBR IV features auto-scanning for hands-free operation - no channel changing needed - and automatically selects the strongest signal.
Features include:
- Combined receiver and antenna package for ease of installation
- Dual independent channels for superior automatic beacon tracking
- Fast acquisition times
- Low power consumption gives extended battery life for portable applications
- Automatic tuning for hands-free operation
- Compatible with a wide range of Magellan chart plotters and handhelds
