As speed through water sensors have non-linear error associated with them, greatest speed through water accuracy will be achieved with instruments supporting multi-point speed calibration (ex. i70S Multifunction Instrument Displays, etc.) in contrast to instruments supporting single point speed calibration (ex. i40 Speed/Bidata, i50 Speed/Tridata Instruments, etc.). Should an i40 Speed/Bidata or i50 Speed/Tridata Instrument be installed onboard the vessel, then speed will be most accurate when the boat's actual speed through water matches that which the instrument was calibrated at. Accordingly, should the vessel be used in a performance manner (ex. racing, etc.), then it would be recommended that an i70S Multifunction Instrument w/iTC-5 Analog Instrument Converter be interfaced to the speed through water transducer. Should the vessel be used in more leisure oriented manner (ex. cruising, day sailing, etc.), then it would be recommended that an i40 Speed/Bidata or i50 Speed/Tridata Instrument be interfaced to the speed through water transducer.
