@Tonci,
I have noticed the bearing read on the scratchpad next to the hydrophone is always 1 degree higher than what sonarman orally reports when you tell him to follow the target. So which bearing number do you go with? Right now, I don't know which one is correct so I take average of the 2 numbers. Say if scratchpad show 72 and sonarman says 71, I use 71.5 for my mapwork. Is that a good way to do this?
