T108-868 Wireless Wind/Speed/Depth System (3 Transducers)

The T108-868 Wireless Wind/Speed/Depth System is a flagship instrument package from Raymarine’s Micronet series, delivering a complete set of wireless sailing data – wind information, boat speed, and depth – all with zero wires. It includes everything needed to equip a sailboat with state-of-the-art instrumentation: a T120 wireless wind transmitter (anemometer) for the masthead, a T910 through-hull triducer for speed, depth, and temperature, and two displays in the cockpit – the T111 multifunction dual digital display and the T112 multifunction analog wind display. All components communicate over a secure wireless link (868 MHz) so there’s no mast cable or hull wiring to install.

At the top of the mast, the T120 wind vane captures apparent wind speed and angle and transmits the readings wirelessly. It’s solar-powered and ultra-light, eliminating the need to run wiring down the mast. This not only simplifies installation but also reduces weight aloft, which is a performance benefit for racing sailors. Through the hull, typically near the bow, the T910 triducer is mounted flush – with a single fitting it provides depth soundings, speed through water (paddlewheel), and water temperature. These readings are broadcast to the system (via the hull transmitter) with the same reliability as a wired connection, but without any through-bulkhead cabling.

In the cockpit, you have two solar-powered displays to make sense of all this information. The T111 Dual Digital Display can show any two data points simultaneously (for example, boat speed and depth, or VMG and wind shift angle) on large digits, while the T112 Analog Wind Display gives you an intuitive 360° needle for wind direction along with a digital readout for wind speed. Both displays are environmentally powered – they charge themselves via built-in solar panels and can run for around 300 hours on a charge. This means no changing batteries or running external power cables; they are truly self-sufficient instruments. The displays are also interchangeable in the sense that they share data on the network, so you could configure them to show whatever is most important to you at any given time. For example, while sailing upwind you might show depth and speed on the T111 and wind angle on the T112; off the wind, you might switch T111 to show VMG or course info. The flexibility is there to tailor your instrument layout to your needs.

The T108-868 system shines in ease of installation and use. Without any wiring to snake through the mast or deck, the time and effort to outfit a boat with this suite is drastically reduced. Many sailors can install this system themselves: mount the wind vane on the masthead (typically using a simple bracket or the existing wind instrument mount), install the triducer in the hull (using the supplied thru-hull fitting), and then mount the displays in the cockpit or on bulkheads – and that’s it. There’s no need to unstep the mast or pull cables, which is a huge plus whether you’re doing a new fit-out or upgrading an older boat. Once installed, the system is maintenance-light: the sealed, watertight units mean no corrosion issues and no water intrusion, even in harsh marine conditions. The wireless network is very robust and has a range sufficient for any normal boat size (and even larger yachts), so you won’t experience dropouts. And since it’s wireless, adding or removing components (like adding a second wind display at the nav station, or taking a display home for safe-keeping in the off-season) is straightforward.

Applications: The T108-868 is ideal for performance sailboats and cruising yachts alike. Racers will love the reduction in weight and the ability to quickly deploy or remove instruments (useful for trailered racing boats or one-design classes). Cruisers will appreciate not having to tear apart the headliner or drill holes in the deck to run cables – preserving the boat’s interior and structural integrity. It’s also great for charter or club boats, where minimal maintenance and high durability are key; there are no connectors to fail and the units are fully sealed against water. The analog wind display (T112) gives an at-a-glance understanding of wind shifts and gusts, which is invaluable for sail trim and course decisions, while the digital display can provide precise numerical data. Expandability is built in: you can add extra Micronet displays (such as the large-digit T110 for the mast or a portable T113 remote, etc.), and the system can interface with other onboard electronics via a wireless interface if needed, allowing you to feed NMEA data to a chartplotter or receive GPS info on your Micronet displays. In summary, the Raymarine T108-868 offers a full suite of sailing instruments in one wireless package, delivering the critical data you need – wind, speed, depth – with the freedom and simplicity that modern wireless technology provides. It’s a future-proof setup that enhances both the performance and enjoyment of your time on the water.
