A method I use to center a contact is to look for where the "ends" of the sound are (where it fades out completely and I can no longer hear it). The contact is in the center.
When dealing with a convoy at distance, I use this method to discover which way the convoy is moving before I move to intercept. I head for the quiet end of the sound in the forward direction of the convoy, as it will take me some time to get there, putting me ahead of the convoy where I can wait...
The "width" of the sound tells me if they are getting closer or moving away. The wider the spread, the closer the convoy/ship.
I like the idea of using the training mode for learning the ranging with the hydrophone! I will give this a try later!
