ZEUS nautical charts

Chartplotter with full range of functions
The integrated 10 Hz GPS receiver and multi-touch display with the latest pinch-to-zoom technology make the 5" display a fully functional chart plotter. Take advantage of Navionics+ and C-MAP MAX-N+ nautical chart support and choose from a variety of sailing areas.

Award-winning sailing features
Experience the highly acclaimed B&G Sailing/Cruising features such as SailSteer™, SailTime™, Laylines, Windplot and enhanced display of sailing instruments with the B&G Vulcan 12R. These functions not only boost your performance in regattas, but also allow you to enjoy a relaxed afternoon cruise.
To take full advantage of the B&G sailing functions we recommend the B&G WS310 or WS320 (wireless) wind sensor. This can be easily connected to the B&G Vulcan via the NMEA2000 network and gives you the exact wind direction and speed.


On the easy-to-read Sailsteer™ display, cruicial sailing parameters such as wind information, speed, tide, course, course over ground, layline and waypoints can be displayed directly.

This gives you the information you need at your fingertips.

Plan your regatta or your next journey effectively. SailingTime™ keeps you up to date and always lets you know how long it will take to get to a waypoint. It calculates the time you’ll spend on each tack, taking into account wind and tidal effects. This gives you an accurate ETA at your destination.


Be on the line as the gun goes with RacePanel. Such important regatta functions only pro navigators have enjoyed, until now. With time, distance and position data, the B&G RacePanel helps you get off to a perfect start in the regatta, all on a single display.

  • Dynamic motor parameters

Simple integration into existing systems
Already have a chartplotter on board? Regardless of whether you use Raymarine, Simrad or Garmin devices, the B&G Vulcan 12R NMEA2000 interface makes it extremely easy to integrate seamlessly into existing systems.

The B&G Vulcan 12R is the perfect addition to your current setup. Use the B&G Vulcan 12R as a control unit for your Simrad, Lowrance or B&G autopilot.
Take advantage of the wide range of possible applications, which are made possible by integrated NMEA2000 interface as well as the space-saving installation dimensions.

System example - Autopilot control unit
The B&G Vulcan 12R makes a perfect control unit for your Simrad, Lowrance or B&G autopilot. Use the full operating possibilities of an autopilot display in combination with the navigation capabilities of a similarly fully functional chart plotter. With the B&G Vulcan 12R you will have a powerful combination.


Latest radar technology

The B&G Vulcan 12R series is compatible with the latest VelocityTrack™ Doppler radar technology of the HALO20+ and HALO24 radar antennas. Take advantage of colour-coded echoes to quickly identify incoming and outgoing targets. You can of course use conventional HALO20 and 3G and 4G broadband radar antennas with the B&G Vulcan 12R.
HALO radar antennas are connected via the ethernet port of the B&G Vulcan 12R.


ForwardScan­® support


Know what's in front of you!
In combination with the optional Navico ForwardScan® transducer, the Vulcan 12R provides a 2D sonar image of the seabed in front of your boat. In shallow, unknown or poorly mapped waters, the ForwardScan® function helps you avoid running aground. It is also a very useful tool in the search for a safe anchorage.

B&G's HALO20+ Pulse Compression Radar uses innovative VelocityTrack Doppler technology to instantly identify hazards at short and long range. Thanks to its unbeatable rotation of up to 60 rpm, the 20" radar antenna offers a near real-time view and gives you the ultimate in collision avoidance.

The ultimate view for collision avoidance
Thanks to its maximum rotational speed of up to 60 rpm, the HALO20 radar antenna delivers a full 360° scan every second. Thanks to these near real-time updates, you get the ultimate view and can quickly and proactively avoid potential collisions. In addition, the Halo Radar provides crystal clear images that make navigation easier even in poor visibility and densely populated waterways.

VelocityTrack ™ Doppler technology integrated
Improve situational awareness and reduce the risk of collision thanks to VelocityTrack Doppler technology! The technology gives you immediate visual feedback on whether targets are approaching or moving away. You no longer need to select individual targets manually. The Doppler effect immediately checks every target detected by your radar automatically. Potential dangers are accordingly marked in colour.

Absolutely satisfied, good quality and easy assembly....
Already in use... the assembly turned out to be a bit more difficult than expected, it took 8 hours. Cables are very stiff and difficult to lay (but well protected). I had the adapter for the radar antenna made. The template that came with it helped a lot.
Can highly recommend this set...
