Meet the Digital Yacht iSeaSense Speed/Depth/Temp/Wind Pack — a complete marine instrumentation system (Model ZDIGISSPK2) that brings depth, speed, water temperature and wind data to life on any smartphone, tablet or chart display. Built on a robust NMEA 2000 backbone with wireless connectivity, iSeaSense delivers fast, beautifully rendered data pages with ultra‑smooth 5 Hz updates.

• 5 Hz updates ensure rapid, reliable readings: Depth updates at 1×/second, Speed at 5×/second, and Heel/Trim at 10×/second, with a transducer that measures depth, boat speed, water temperature and heel/pitch for accurate VMG calculations. Depth operation uses 235 kHz to minimise interference with 50/200 kHz fish finders and sounders, with a maximum depth of 100 m.
• Includes a WND100 wind sensor with a 20 m cable and a direct T interface to the NMEA 2000 backbone — no heavy mast-top cabling or complex terminations required.
• Comprehensive expansion and wiring: a full NMEA 2000 backbone cabling kit is included, plus a spare cable and connection point for additional devices. An extra NMEA 2000 T-piece makes it easy to add sensors or displays as your system grows.
• Designed for seamless integration and sharing: data can be sent to other NMEA 2000 instruments and displays, including GPS, AIS, and electronic compasses, or to chart plotters on the network.
• Web interface— no apps required. On a connected device, open your browser and go to iSeaSense.local to access an optimised touch-screen display. Calibrate wind and view true and apparent wind speed/angle, plus VMG calculations. The interface works across iOS, Android, PC, Linux and MAC and supports up to 3 connected devices.
• Compatibility and data sharing: the instruments’ data can be used by hundreds of popular navigation apps & software such as Navionics, TZ iBoat, OpenCPN, SailGrib, and more, providing versatile onboard connectivity.

Whether you’re racing, cruising or navigating challenging coastal waters, the iSeaSense Speed/Depth/Temp/Wind Pack gives you precise, real‑time marine data, displayed exactly how you want it — on the device you already carry. Elevate your boat’s instrumentation with a flexible, expandable system that’s simple to install and easy to use.
