Raymarine T108 Wireless Wind, Speed & Depth System with T910 Triducer

Overview

The Raymarine T108 is a wireless wind, speed and depth instrument system for sailboats that need cockpit data without running instrument cables through the mast and around the hull. It combines a T111 wireless dual digital display, T112 wireless analog display, T121 hull transmitter, T120 wireless wind transmitter and T910 through-hull triducer for depth, speed and water temperature.

This system is a practical fit for cruising and club-racing sailboats where wind angle, wind speed, boat speed, depth and log information need to be visible at the helm or cockpit. The wireless displays are solar powered, have 300 hours of autonomy, use backlighting with 3 levels and are submersible to 10 m, which matters on exposed cockpits that see spray, rain and washdowns.

Key features

• Wireless Micronet instrument package for wind, speed, depth, distance and related sailing data.
• T120 masthead wind transmitter measures apparent wind speed and direction without a mast cable run.
• T910 through-hull triducer reads depth, speed and water temperature through one flush-mount fitting.
• T111 dual digital display shows two lines of data at the same time with 20 mm digital readout.
• T112 analog display gives wind information in an easy-to-read analog format with 14 mm digital readout.
• Solar-powered displays offer 300 hours of autonomy and reduce dependence on the boat electrical system.
• Displays are submersible to 10 m, suitable for open cockpit locations exposed to spray and weather.
• NMEA compatibility is available through an optional T122 wireless interface when integration with other equipment is required.

Variants

The T108 system is offered in two wireless-frequency configurations. The package contents and instrument functions remain the same, while the operating frequency changes by region.

The frequency version should match the vessel’s region of use and local radio requirements, especially when replacing or adding to an existing Raymarine wireless instrument setup.

• T108-916: Wireless Frequency 916MHz. This version is for Americas, Asia and Australasia installations.
• T108-868: Wireless Frequency 868MHz. This version is for Europe installations.

Installation and setup

The wireless layout keeps installation simpler than a fully wired wind, speed and depth system. The wind transmitter mounts at the masthead, the triducer installs through the hull for depth, speed and temperature, and the hull transmitter sends the transducer data to the cockpit displays over the Micronet wireless network.

The displays can be positioned where the crew can read them while steering, trimming or checking depth on approach. For best results, the frequency version should match the onboard Raymarine wireless components already installed on the boat.

Electrical and system integration

The T111 and T112 displays use solar charging with internal batteries, reducing the amount of wiring needed around the helm or bulkhead. The T121 hull transmitter uses an internal lithium battery with up to 300 hours of disconnected operation and can also be powered from the boat’s DC system or charged with an optional solar panel.

For boats that need data shared outside the wireless instrument network, NMEA integration requires an optional interface. Wired SeaTalkng integration for the wind transmitter can also be handled through an optional MicroTalk gateway when the rest of the boat electronics are built around a Raymarine wired network.

Use cases on board

This system suits sailboats where a clean cockpit installation and reduced mast wiring are important. It is especially useful for owners refitting older instruments, race crews that need wind and speed data visible from the cockpit, and cruisers who want depth and speed information without building a large wired instrument network.
