Key Benefits and Applications

• Exceptional readability — Oversized digits on two lines keep your critical numbers legible from the helm or rail, perfect for day sailors and cruisers who demand instant clarity.
• All essentials in one view — Depth, speed, temperature and battery voltage presented cleanly so you can trim sails, plot approach and monitor systems without cycling through menus.
• Instant trend awareness — On‑screen arrows show rising or falling depth and speed, helping you react early in shallow approaches, tidal gates and manoeuvres.
• Smart alerts for safer passage — Customisable depth, speed and battery alarms add a proactive safety layer during night sailing, channel transits or when training crews.
• Seamless network integration — NMEA 0183 input and output plus the internal AdvanSea bus allow the unit to work solo or as part of a broader instrument suite on yachts and motorboats.
• Built to handle real marine conditions — A sealed front face and anti‑fog display support reliable viewing in spray, rain and temperature swings typical of coastal cruising.
• Fast setup and intuitive operation — Simple front keys, quick access to backlight and menu, and a simulation mode make commissioning and crew familiarisation straightforward.
