Raymarine i70s Wireless Wind Instrument Kit, DST800, SeaTalkng

Overview

The Raymarine T70347 is an i70s wireless wind instrument package for sailboats that need wind, depth, speed, log, and water temperature data on a Raymarine instrument network. It combines the i70s multifunction color instrument display, a T120 wireless masthead wind transducer, a Micro-Talk Wireless Performance Sailing Gateway, a T113 wireless remote display, an Airmar DST800 through-hull transducer, and the SeaTalkng parts needed to build a basic backbone.

The i70s display gives the helm or cockpit a 4.1 inch color screen for viewing wind, speed, depth, navigation, engine, fuel, environment, and AIS repeater data when those data sources are available on the network. The display runs from a 12 V DC SeaTalkng supply, with a 9 V DC to 16 V DC operating range and protection up to 32 V DC, so it suits typical 12 V onboard electronics installations.

This package is most useful for sailors who want wind data without running a cable down the mast, while still keeping the rest of the instrument system on a wired SeaTalkng backbone. The Micro-Talk gateway bridges the wireless Micronet wind components to SeaTalkng, and NMEA 2000 integration is possible with the correct SeaTalkng to DeviceNet adaptor.

Key features

• Complete sailing instrument package with i70s color display, wireless wind sensing, wireless remote display, DST800 through-hull depth, speed, and temperature sensing, and SeaTalkng network hardware.
• T120 masthead transducer measures apparent wind speed and direction over Raymarine wireless Micronet, reducing the need to run wind wiring through the mast.
• Micro-Talk gateway connects Micronet wireless data to a wired SeaTalkng network and supports wind angle, wind speed, depth, boat speed, temperature, heading, GPS, time, date, and navigation data.
• i70s display has a 4.1 inch TFT LCD screen with 320 x 240 resolution, 16 bit color, and 1,200 cd/m2 brightness for use at the helm or companionway.
• i70s waterproofing is rated IPX6 and IPX7, which matters for exposed cockpit mounting where spray and washdowns are part of normal boat use.
• DST800 through-hull transducer combines depth, speed through water, and water temperature in a single 2 inch fitting.
• SeaTalkng backbone parts are included, with a 5 m backbone cable, power cable, 5-way block, T-connector, and network terminators for a basic instrument network layout.
• Expandable with compatible Raymarine wired and wireless instruments, sensors, multifunction displays, and autopilots as the onboard system grows.

Installation and setup

The wireless wind transmitter mounts at the masthead and sends wind data without a long mast cable run, which can simplify a refit on an existing rig. The Micro-Talk gateway mounts on board and plugs into the SeaTalkng network, so it should be located where it has a suitable network connection and a practical wireless path to the Micronet components.

The DST800 is a through-hull transducer, so installation requires a suitable hull location, access inside the boat, and correct sealing practice for the hull material and fitting. The i70s display is surface mounted and connects to the network through its SeaTalkng connector.

Electrical and network compatibility

The system is built around Raymarine SeaTalkng networking. The i70s display and Micro-Talk gateway are powered from the SeaTalkng network, and both operate on a 12 V DC nominal supply with a 9 V DC to 16 V DC operating range.

For boats with NMEA 2000 backbones, a SeaTalkng to DeviceNet adaptor is required. This keeps the package practical for mixed electronics installations, but the exact network layout should be checked before ordering cables or planning the final mounting positions.

Use cases on board

This package fits coastal cruising boats, club racing sailboats, and performance-minded cruising setups where wind shifts, apparent wind angle, boat speed, and depth all need to be visible without spreading data across separate stand-alone instruments. It is also a practical starting point for a Raymarine-based instrument upgrade because the kit includes the display, sensors, gateway, remote display, and core network parts in one package.
