Imagine slicing through choppy seas during a coastal regatta or plotting a course across open ocean expanses—having instant access to precise wind data, laylines, and tide corrections can mean the difference between first place and watching the fleet disappear over the horizon. The B&G Zeus 3S 12 elevates your sailing experience with its super-responsive 12-inch multi-touch display, blending cutting-edge sailing-specific tools with rugged marine reliability. Tailored for serious cruisers and competitive racers, this chartplotter delivers real-time insights that help you anticipate tacks, optimize routes, and stay ahead of the competition, all while maintaining crystal-clear visibility even in the harshest conditions.
Crafted with input from elite sailors, the Zeus 3S 12 goes beyond basic navigation. Its SolarMAX HD IPS screen shines at 1200 nits, ensuring you spot critical data through polarized sunglasses or blinding glare. The hybrid controls—intuitive touchscreen plus rotary dial and keypad—keep you in command during gloved hands or pounding waves.
In the heat of a race, seconds count. SailSteer consolidates your essentials—true wind angle, boat speed, course over ground—into one glanceable view, eliminating the need to bounce between screens. Laylines dynamically adjust for leeway and velocity made good, guiding perfect tacks that shave minutes off your upwind legs. For cruisers, SailingTime crunches wind angles and tides to predict arrival times realistically, turning "ballpark" ETAs into reliable plans.
RacePanel transforms starts: sync to the committee boat, monitor distance-to-line, and time your roll perfectly. Pair it with an H5000 processor for pro-level data fusion, where every sensor feeds into hyper-accurate polars and routing. Racers love how it overlays start lines on charts, while cruisers appreciate autopilot integration for hands-free wind-vane steering or contour tracking in unfamiliar bays.
Customize quick-access keys for RacePanel during pre-start sequences. Practice in lighter airs to dial in your timing—many winners credit this feature for clean starts in shifty breezes.
Rated IPX6/7 and shock-tested to 20G, the Zeus 3S 12 thrives from polar expeditions to tropical tradewinds. Operating from -15°C to +55°C, it shrugs off spray, vibration, and extreme swings. Power it standalone for solo day sails or network it into a full ecosystem—autopilot commissioning via touchscreen, SonicHub for zone-controlled audio, even CZone digital switching for lights and pumps.
Wi-Fi unlocks wireless updates, app mirroring, and hotspot tethering for GRIB files offshore. Bluetooth handles wireless remotes, while dual video inputs let you monitor engine cams or aft views. Storage? 16GB internal plus dual microSD slots for charts, routes, and tracks galore.
