1.0 OVERVIEW
EdgeTech provides an optional interface to magnetometers for 4205 series sonar systems. The
magnetometer option provides for the simultaneous gathering of the earth’s magnetic field strength
along with side scan data.
EdgeTech’s 4205 series side scan systems can be towed simultaneously with various magnetometer units.
Currently EdgeTech offers an interface package for Marine Magnetics ‘SeaSPY’ and Geometrics ‘G-
882’magnetomers. Other brands and models can also be interfaced. The magnetometer interface involves
the following:
1. Mechanical
2. Electrical
3. Digital telemetry
The client needs to specify, when placing the order for a combined Side Scan / Magnetometer system, the
brand and model number of the magnetometer. In the situation where the client wants to interface a
magnetometer to an existing Side Scan system, an interface kit needs to be ordered from both EdgeTech
and the magnetometer supplier.
