I was just looking at the ITC-5. "Please note the ST40/i40/i50/i60 and ST60+ displays cannot calibrate the iTC-5. Only the i70 has full transducer calibration. The ST70/ST70+ can calibrate the Depth, Wind and Speed/Temp transducers (not Rudder or Compass). If you don't have an ST70/ST70+ or i70 in your system, then the ST40/i40/i50/i60/ST60+ displays must be interfaced directly to the relevant analogue transducers."
