i50 Tridata replacing ST70 SeaTalk Raydata

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum MissGuided,

Speed/Temp Transducers which were designed for use with the Raydata Instruments should indeed be compatible with the i50 Tridata and i50 Speed instruments. It is recommended that you verify that the speed/temp transducer's leads have each been mated to the corresponding color coded terminal of the i50 Tridata. If so, and the problem persists, then it recommended that the i50 Tridata display be Factory Reset (see the manuals section concerning dealer calibration options). Should the problem persist following the Factory Reset operation then the fault may be rooted in the transducer. Given the age of the speed/temp transducer, it is quite possible that it may have failed. Replacement speed/temp inserts are available from Gemeco, Inc. (Airmar’s US distributor (803 693 0777)) for Airmar transducers, including those branded for Raytheon and Raymarine.
