 SECTI O N 1 :
OVERVIEW
EdgeTech’s magnetometer interface option allows users with a 4125 LT with Mag Option system to
simultaneously tow a magnetometer along with the towfish. In doing so, users can gather side scan data
while simultaneously recording the Earth’s magnetic field strength throughout the survey.
NOTE: The 4125 E-Net side scan system is not compatible with the
Mag Option.
Currently, EdgeTech offers an interface package for Marine Magnetics SeaSPY II and Mini Explorer
magnetometers. No other brands or models can be interfaced with the 4125 LT at this time.
The magnetometer interface involves the following connection types to function:
• Mechanical
• Electrical
• Digital telemetry
The client needs to purchase the Universal Link (TAB) when placing the order for a combined Side Scan /
Magnetometer system, and to provide the brand and model number of the magnetometer they would
like their system to interface with (see Figure 1-1). If a 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.
