I have been reading the Mega Live manuals. I have not seen any information about alignment (calibration) in relation to the boats heading sensor. I would think it would be important for marking waypoints and giving validity to the boat icon's direction arrow for boat and mega transducer alignment. Am I overthinking this or have I missed an item in the documentation. Thanks Bob
OR, Are the waypoints generated from a Mega screen accurate? AHRS is still pretty much a magic box to me. I have read some on it, but not sure how it relates to accuracy of waypoints on Mega.
