This must be done away from all magnetic and metal sources, and in most cases, it
will have to be done off the ship.
First, enable the towfish compass calibration mode; then rotate the towfish slowly 360
degrees in a circle (for more than a minute). At the same time you must pitch and roll
the towfish beyond its 20 degree limits, we suggest 45 degrees to be safe.
Excellent calibration results have been obtained by enabling the
compass calibration and towing the towfish in a series of three cir-
cles with the boat.
