Raymarine i70s Wireless Wind Instrument Kit, DST800 Transducer, EV1 Heading Sensor

Overview

The Raymarine T70348 is a complete i70s sailing instrument package that brings wireless wind, heading, depth, speed and water temperature data onto a SeaTalkng network. It is built around the i70s multifunction color instrument, the Micro-Talk Wireless Performance Sailing Gateway, a T120 wireless masthead transducer, an EV1 heading sensor and a DST800 through-hull transducer.

The i70s display uses a 4.1 inch TFT LCD with 320 x 240 resolution and IPx6/IPx7 water protection, making it suitable for exposed helm and cockpit installations. The Micro-Talk gateway links Raymarine Micronet wireless instruments with wired SeaTalkng equipment, while the EV1 9-axis sensor supplies heading and motion data for compatible onboard electronics.

This package suits sailboats that need a clean instrument upgrade without running a conventional wind cable down the mast. It is especially useful for cruising and club-racing boats where wind angle, boat speed, depth, water temperature and stable heading data all need to be visible at the helm.

Key features

• Complete instrument package for wind, heading, depth, speed through water and water temperature data on compatible Raymarine systems.
• Includes the i70s multifunction display with a 4.1 inch screen, large data views and SeaTalkng networking.
• Micro-Talk gateway bridges Raymarine Micronet wireless instruments with wired SeaTalkng equipment and compatible autopilots.
• T120 wireless masthead transducer sends wind speed and wind angle data without a wired mast run.
• EV1 heading sensor uses 9-axis sensing to monitor heading, pitch, roll and yaw, with dynamic accuracy within 2 degrees.
• DST800 through-hull transducer combines depth, speed and temperature sensing in a single 2 inch fitting.
• SeaTalkng backbone parts are included for a basic network, including power, backbone cabling and a 5-way connector block.
• i70s supports SeaTalk, SeaTalkng and NMEA 2000 integration when the correct adapter cables are used.

Installation and setup

The kit is intended to form a basic SeaTalkng instrument network. The included backbone cable, power cable and 5-way block give the installer a starting point for connecting the i70s display, Micro-Talk gateway, EV1 heading sensor and related network devices.

Plan the installation around three main locations: the i70s display at the helm or navigation area, the T120 wind transducer at the masthead and the DST800 in a suitable through-hull position. The EV1 heading sensor can be mounted above or below deck, but it should be placed where magnetic interference and heavy vibration are minimized.

Compatibility and system integration

The i70s display can show wind, speed, depth, tridata, engine, environment, fuel and navigation information when the required data is present on the network. For NMEA 2000 backbones, SeaTalkng to DeviceNet adapter cabling is required.

The EV1 can supply heading information to compatible Raymarine chartplotters, radar systems, instruments and autopilots. The Micro-Talk gateway also allows wireless wind data to be shared with compatible wired Raymarine equipment, which helps when adding wireless wind sensing to an existing SeaTalkng-based installation.

Marine use notes

This package is a strong match for sailboats where cockpit readability, wind data and heading stability matter during sail trim, coastal cruising and race starts. The wireless masthead approach can simplify refits where pulling new wind wiring through the mast would be difficult or expensive.

The DST800 still requires a proper through-hull installation, so hull material, access inside the boat and haul-out timing should be checked before ordering. The electronics are built for 12 V DC SeaTalkng systems, so power planning should follow Raymarine network loading and marine electrical practice.
