Note
The GPS antenna location (position data output point) is pre-programmed into
the Seapath 130 sensor unit at the factory. This location is based on using the
centre of the M3 Sonar transducer face as the reference point and on using a
standard Pole Mount height. If you have adjusted the height of the Pole Mount (or
are using your own Pole Mount for deployment) you will need to change these
offsets in the Seapath operator software.
