[CA11] Axiom 12 3D Vision goes sideways

RE: [CA11] Axiom 12 3D Vision goes sideways

The symptoms identified have not been previously reported, making the problem with this system somewhat unique. While the problem may be rooted in the transducer(s), it may be also indicative of a fault with the installation or within the MFD's sonar processing circuitry itself. As you have hinted, choice of a location for the transducer with respect to magnetic field sources is important when using the AHRS within a RV transducer. It is certainly possible that the reported image spinning may be caused by such magnetic fields. However, given that you are reporting that the bottom appears to move at about a 45 degree angle to the boat's real motion when the AHRS is OFF would indicate a secondary issue with the elements of the transducer(s) or within the RV sonar processing circuitry of the Axiom RV MFD as the system will revert to COG or orientation of the sonar image

When troubleshooting, one starts with the basics of the installation and environmental factors such as transducers ... nothing may be taken for granted and all must be verified ... hence the requests for very specific items. Regarding additional depth transducer within the system, I had been specifically interested in whether a second fishfinder transducer had been interfaced to the Axiom RV MFD ... this does not appear to be the case. Instrument depth transducers would have not impact upon fishfinder performance. As the boat is quite far away, you may want to consider contacting an Certified Raymarine Installer to visit the vessel to obtain the requested photos, verify correct port/starboard installation as well as correct fore/aft installation, inspect the transducers and its cables for any obvious signs of damage or modification / splicing. Should all appear correct then it would be recommended that the MFD be removed and sent to Raymarine’s Product Repair Center to be bench checked / serviced. (as the boat is now on the hard).
