Raymarine’s T104 combines all the core instruments – wind, speed, and depth – into one system, with the added ability to interface with your onboard electronics via NMEA. The kit features the high-contrast T112 analog wind display, giving the helm a clear view of wind direction and strength, and the dual-line T111 digital display providing real-time speed through water and depth readouts. The wireless T120 masthead wind vane delivers true and apparent wind data, while the T912 and T911 thru-hull sensors accurately measure depth and boat speed. All of this information is gathered by the T121 hull transmitter and sent wirelessly to the two displays, allowing the crew to monitor the most important parameters at a glance.
What sets the T104 apart is the included T122 NMEA interface, which opens the system to the rest of your onboard electronics. Through it, wind, speed, and depth data can be sent to a chartplotter, autopilot, or MFD, and you can also receive external information (e.g. GPS course) for display on the instruments. Like all Micronet instruments, every component in the kit is solar-powered and communicates wirelessly – installation is simplified with no holes to drill for cables, and maintenance is minimal. The T104 is the perfect all-in-one solution for sailors looking to modernize their boat with a full instrument suite that is reliable, easily expandable, and integration-ready.
- Ideal for sailing yachts needing a complete set of navigation instruments – the T104 provides wind, speed, and depth in one coordinated package.
- Recommended for boats looking to network instruments with a chartplotter or autopilot – thanks to the NMEA interface, data is shared bidirectionally with the rest of your onboard electronics.
- Suitable for offshore and cruising yachts – the wireless system reduces issues associated with long cable runs through the boat, increasing reliability on extended voyages.
- An excellent upgrade for replacing outdated systems – the T104 consolidates multiple separate instruments into one unified kit, which can be further expanded if needed (e.g. with additional displays or sensors).
