Raymarine i70s Wireless Wind Instrument Kit, DST800, EV1 Heading Sensor, SeaTalkng Backbone

Overview

The Raymarine T70349 is an i70s wireless wind, depth, speed, temperature, heading, and SeaTalkng backbone package for sailing instruments. It brings together the i70s multifunction color display, T222 wireless vertical masthead wind transducer, Micro-Talk wireless gateway, EV1 heading sensor, T113 wireless remote display, and DST800 through-hull transducer so a sailboat can show wind, depth, speed through water, water temperature, and heading data from one integrated package.

The i70s display has a 4.1 inch TFT LCD screen with 320 x 240 resolution, 1,200 cd/m2 brightness, IPX6 and IPX7 waterproofing, and a 9 to 16 V dc operating range. The Micro-Talk gateway also runs from the SeaTalkng network at 12 V dc and bridges Raymarine Micronet wireless instruments with SeaTalkng and NMEA 2000 systems through the proper adapter.

This package makes sense for racing sailboats and performance cruisers where wind angle, wind speed, heading, boat speed, depth, and temperature need to be visible at the helm, on deck, and across the onboard instrument network.

Key features

• System package combines i70s display, wireless masthead wind sensing, EV1 heading data, DST800 through-hull depth, speed and temperature sensing, wireless remote display, and SeaTalkng backbone components.
• T222 wireless vertical masthead transducer places the wind sensor above the masthead to reduce interference from sails, rigging, updraft, and turbulence.
• Micro-Talk gateway links Raymarine Micronet wireless instruments with wired SeaTalkng equipment and supports NMEA 2000 integration when the correct DeviceNet adapter is used.
• i70s display shows digital, analog, and graphical data pages for wind, speed, depth, tridata, engine, environment, fuel, navigation, and AIS repeater information from compatible network sources.
• EV1 sensor uses a 9-axis sensing system for heading, pitch, roll, and yaw data, with heading support for autopilots, radar overlay, MARPA, chartplotters, and instruments.
• DST800 transducer combines depth, speed through water, and water temperature in a 2 inch through-hull fitting with a 200 kHz depth frequency.
• i70s and Micro-Talk components are rated IPX6 and IPX7, suitable for exposed cockpit and deck-adjacent installations where spray and washdowns are part of normal boat use.
• Included T113 remote display repeats and controls wireless instrument data, with solar power, integrated lithium batteries, three backlight levels, and submersion rating to 33 ft or 10 m.

Installation and setup

The kit includes the core SeaTalkng cables, connectors, terminators, power cable, and 5-way block needed to establish a basic instrument backbone. The i70s display is normally surface mounted at the helm, nav station, or cockpit panel, while the Micro-Talk gateway can be surface mounted on deck or below deck where it has a suitable connection to the SeaTalkng network and wireless instruments.

The DST800 is a through-hull sensor, so hull material, existing transducer fittings, haul-out timing, and access inside the boat should be reviewed before installation. Its retractable housing with water valve helps with service access after the fitting is installed.

Compatibility and integration

The i70s works with current SeaTalkng networks and can connect with NMEA 2000 networks through the required SeaTalkng to DeviceNet adapter. It can also be used with first generation SeaTalk networks when the correct SeaTalk to SeaTalkng adapter cable is added.

The EV1 heading sensor connects through SeaTalkng and can be mounted above or below deck. It is useful when the system needs stable heading information for sailing calculations, autopilot behavior, radar overlay, MARPA tracking, or chartplotter heading modes.

Use cases on board

On a performance cruiser, this package gives the helm a clean view of the numbers that matter during sail trim, coastal passages, and changing weather. On a race boat, the wireless remote display and masthead wind sensor help crew monitor wind trends, speed trends, VMG to wind or waypoint, SOG, COG, performance graphing, and race timer information from useful positions on deck.

It is a strong fit for boats moving from older instrument layouts to a mixed wired and wireless Raymarine system, or for a new sailing electronics installation where the owner wants wind, depth, speed, temperature, and heading data in one coordinated instrument package.
