SYSTEM BREAKDOWN
The Diver Mag 1 is a Proton Magnetometer which consists of a sensor bottle assembly, a amplifier board, a micropro-
cessor board, and a control panel. All components are housed in a PVC housing.
The PVC housing consists of a waterproof section in the front which contains the sensor assembly, and a waterproof
section in the rear which houses the electronics. The interconnecting tube in the center floods with water. The two
waterproof sections are electrically connected by a waterproof cable that travels inside of the interconnecting tube.
The sensor bottle assembly is quite heavy, so a positive buoyancy chamber is built into the front section of the Diver
Mag 1. The buoyancy chamber has an o-ring sealed vent bolt that will allow water into the chamber. This feature
allows the operator to adjust the buoyancy of the unit by allowing a controlled amount of water into the buoyancy
chamber.
The Diver Mag 1 must be capable of being tuned from 24,000 to 61,000 gammas (see world map). To optimize tuning,
a ten position binary switch (100 different combinations) is used to cover the full range of gammas. Each switch
position covers a large area, and the position that covers your area has already been selected at the factory (this will
be explained later). For field tuning the Control Panel is removed which gives access to the tuning switch. See P6 on
page 19 for more details on tuning.
