advanSea Speed S400 Display Only — Clear, Stand-Alone Marine Speedometer

The advanSea Speed S400 Display Only is a dedicated cockpit data hub built for serious sailors who demand instant access to critical speed and navigation information. As a stand-alone display, it delivers race-level visibility with cruising practicality, drawing data from intelligent transducers or any NMEA0183 source for a streamlined, reliable reading in any weather or sea state.

Crystal-clear readability in every condition

Designed for sun-drenched decks and spray-filled moments, the S400 uses a 45 mm high-contrast digit set on a transflective monochrome LCD with a wide viewing angle. Amber backlit controls offer five brightness levels to minimize glare while keeping essential data at your fingertips. The front is IP66-rated and protected by an anti-fog coating, ensuring a clear, legible display even in challenging conditions.

Comprehensive data at a glance

• Speed: 0–60 knots, plus GPS speed when connected
• Logs: Total and trip log for complete voyage tracking
• Depth data: Depth-enabled speed display when linked to an NMEA0183 source
• Racing timers: Elapsed time and precise countdown timer for starts and finishes
• Alarms & safety: High/low speed alarms and a low-battery alert
• Temperature & trends: Water temperature and speed trend indicators to identify changing currents
• Testing & modes: Surface speed alarms and a simulation mode for on-shore familiarization

Durable, installation-friendly design

The 112 x 112 mm external unit features a rear locking collar and a 48 mm drilling requirement for a leak-proof bulkhead seal. It operates on 10–16.5 V and draws less than 150 mA, with a wide operating temperature range from -10°C to +50°C for dependable use at sea. It’s compatible with Airmar or Plastimo transducers and can function as a standalone display or integrate with NMEA0183 networks.

Legacy compatibility and flexible deployment

For fleets upgrading or modernizing old installations, the S400 is a ready replacement for Navman 3100 and Northstar 310 series setups that use the same transducers. Build a reliable, high-contrast data hub in your cockpit without the complexity of a full electronic network, or upgrade an existing system to consistently readable speed, depth, and navigation data.

Why this matters for cruisers and racers

Whether you’re chasing precise race starts or cruising with confidence, the S400 delivers fast, unambiguous access to the numbers that matter. It’s designed to be your cockpit’s trusted data anchor—easy to read, quick to interpret, and robust enough to handle the rigors of sailing life. With a two-year warranty and global Plastimo support, you can upgrade with reassurance and focus on the next tack, not technical surprises.
