[CA] [CA11] Sailboat System Upgrade Selection Review

[Chuck - Raymarine - Moderator]

eljacksjr,

From a performance standpoint, it has been our perception that systems featuring a separate depth transducer and separate speed/temp transducer yield better depth and speed performance. Unlike the ST60/ST60+ instruments, the i70 w/iTC-5 supports multipoint speed calibration, which should improve speed performance across a range of boat speeds. Naturally, this is dependent upon having a properly functioning speed/temp transducer and the current transducer should be replaced if it is not functioning properly. Airmar has also introduced a new line of NMEA 2000 ultrasonic speed transducers.
