T103-868 Wireless Speed/Depth System with Transducer

The Raymarine T103-868 is a complete wireless speed and depth instrument kit that delivers reliable data with minimum installation effort. Utilizing Micronet wireless technology, it eliminates the need for cumbersome sensor wiring – the triducer’s measurements are transmitted through the air to the cockpit display, so no drilling through bulkheads or pulling cables down the mast is required. The kit includes a T111 multifunction dual digital display that is solar-powered and simultaneously shows the boat’s current speed and the water depth beneath the keel. A T121 hull transmitter interfaces with the through-hull T910 triducer sensor, which provides three-in-one data: speed (paddlewheel log), depth (sonar) and water temperature. All components are fully sealed and waterproof (submersible up to 10 m, with no internal condensation), ensuring long-term durability in the marine environment. The solar-powered display includes an integrated lithium battery that is so efficient it can run autonomously for up to 300 hours on a full charge, storing energy during daylight to power your instruments day and night.

A standout benefit of the T103-868 system is its fast and flexible installation. A typical setup can be completed in just a few hours even with the boat in the water, since there are no wires to run or holes to cut in your boat’s structure. This saves time and preserves your vessel’s integrity, while also reducing weight aloft (no mast cable means a lower center of gravity on sailboats, yielding an immediate performance boost). The T111 display can be easily mounted anywhere using clip-in cradles, allowing you to place it where you need the information most – and it’s removable for safekeeping. The clear LCD screen and simple button interface make it easy to cycle through data pages and read your speed and depth at a glance, even in bright sunlight or at night (thanks to the display’s backlighting). Because the system is wireless and solar-powered, there’s virtually no maintenance – no corroded connectors or drained batteries to worry about.

Recommended Use Cases: The T103-868 Wireless Speed/Depth System is perfect for sailboat owners (daysailers, cruising yachts, club racers) looking to upgrade their instruments without the hassle of running new cables. It’s equally useful for small powerboats and RIBs that need a quality speedometer and depth sounder but have limited space or owner budget for complex installations. This kit is a great choice for refitting older boats with modern electronics – you can add state-of-the-art instrumentation while your boat remains intact and water-tight. Operating on the 868 MHz frequency (European spec), the Micronet wireless link is robust and resistant to interference, ensuring your data is transmitted reliably even in busy marine environments. Backed by a 2-year warranty (extendable to 3 years upon product registration), the Raymarine T103-868 gives you peace of mind along with cutting-edge convenience. As part of Raymarine’s scalable Wireless Instrument range, this system can be expanded with additional displays (e.g. wind, multi or remote displays) and sensors if needed, making it a future-proof solution for growing your onboard electronics suite.
