B&G Zeus3S 9 Sailing MFD Bundle with HALO20+ Radar

This bundle pairs B&G's 9-inch Zeus3S sailing chartplotter with the HALO20+ pulse-compression radar dome as a complete navigation package for mid-to-large sailboats. The Zeus3S is the chartplotter half: 9 inches of all-weather SolarMAX HD IPS touchscreen with hybrid touch-plus-rotary-dial-plus-keypad control. The SolarMAX HD IPS panel reads in direct sun even through polarized sunglasses, which on a deck under tropical sun matters more than it sounds. The hybrid control set is the right answer for sailing. The touchscreen handles waypoint placement and pan-zoom. The rotary dial handles range and gain adjustments without taking your eyes off the chart. The keypad keeps working when the touchscreen is wet or you've got gloves on for a cold-weather race. It's the input setup most racers settle on after a season of mixed conditions.

The sailing-specific feature set is what separates the Zeus3S from a general-purpose chartplotter. SailSteer consolidates wind data, speed through water, heading, and the next waypoint into a single tactical screen that you can read at a glance during a beat. Laylines plot the optimal tack angles for your boat in real time, factoring in wind shifts and current set, so you can lay the upwind mark without overstanding. RacePanel is the start-line tactical screen with line bias, distance-to-line countdown, and fleet position tracking for clean starts. SailingTime calculates ETA to the next waypoint accounting for tacks rather than assuming you can sail straight there. PredictWind integration pulls professional weather forecasting onto the chart with grib overlays for route planning. If you're a racer, the RacePanel and Laylines features alone justify the upgrade from a generic chartplotter. None of these features are afterthoughts. They're what the Zeus3S was designed around.

The HALO20+ radar in the bundle is the 20-inch pulse-compression dome from the HALO family. Pulse compression is the modern technology that lets the dome detect at long range (up to 36 nautical miles) and at very short range (down to 20 feet) without any of the magnetron tradeoffs an older radar would make. Beam sharpening sharpens target returns digitally so small targets like crab pots, kayaks, and distant whitecaps show up cleanly against background clutter. Dual Range lets you display two range scales simultaneously from the single antenna, which for an offshore cruiser means watching the close-in collision picture and the distant weather cell at the same time without flipping between them.

VelocityTrack Doppler is the headline operational feature on the HALO20+ for cruising and racing safety. Approaching targets paint red on the chartplotter, receding targets paint green, stationary targets stay in standard radar colors. The visual cue is instant: a single glance at the radar page tells you which boats are closing on you and which are running away, without manual target acquisition. Combined with the 60 RPM ultra-fast rotation at ranges up to 1.5 nautical miles, the HALO20+ delivers a near-real-time picture of the close-in traffic environment that traditional 24 RPM radar dom­es simply can't match. For shipping lanes, busy race courses, and harbor entries, the fast scan plus Doppler coloring is the safety upgrade most operators notice first. It's the kind of feature you don't realize you needed until you've used it for a season.

The bundle ships with the HALO20+ dome and a 20-meter signal cable to run from the radar mast position back to the Zeus3S chartplotter. The Zeus3S accepts the radar over its Ethernet port and integrates the radar overlay onto the chart. Both units run on 12V or 24V DC, which covers standard sailboat house bank voltages without converters. NMEA 2000 and NMEA 0183 networking handles the rest of the boat's instruments: wind, depth, speed-through-water, autopilot, AIS, VHF, and digital switching where installed. Built-in Wi-Fi pulls weather and chart updates from the cloud and pairs with the B&G companion app on a smartphone or tablet. ForwardScan sonar is supported through the Marine Network for cruisers who want forward-looking depth in shallow-water approach. The Zeus3S supports the H5000 high-performance instrument processor for serious offshore racing systems. We can spec the full instrument network with you before you order.
