[CA] [CA11] ITC-5 for i70s

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum sailshade,

Product documentation, Raymarine or other, is not generally updated to reflect discontinuation of accessories or the product itself. The M81190 Autopilot Fluxgate Sensor which you have referred to had been principally introduced for use with Raymarine autopilots dating from the 90's through the point when Raymarine introduced the Evolution autopilots. The latter autopilots feature a solid state 9-axis stabilized magnetic heading sensor (EV-1 / EV-2 CCU) versus the non-stabilized mechanical magnetic heading sensor used by the earlier autopilot designs, instrument compasses, and iTC-5. Due to the vastly superior heading performance of the EV-1 and EV-2, coupled with being no longer being able to service most of the older autopilot designs which utilized the M81190 Autopilot Fluxgate Sensor, Raymarine has discontinued production of the M81190. As has been suggested, remaining inventories of these fluxgate sensors are currently in the marketplace and may be used with the iTC-5 & i70/i70S MFID. Given that the combined cost of the iTC-5 and M81190 Autopilot Fluxgate Sensor is only slightly less than that of an EV-1 CCU, that the performance of the EV-1 CCU performance is vastly superior to the M81190 Autopilot Fluxgate Sensor, the life expectancy of the EV-1 CCU should be longer due to its solid state design (i.e. no moving parts), and that the EV-1 CCU may be used as part of a future Raymarine autopilot installation, most seeking to add heading data to their systems will opt for the EV-1 as has been recommended here. The EV-1 CCU requires no calibration via the i70/i70S MFID's user interface.
