User Manual
Introduction
The AQUASCAN name has been established for more than two decades and conveys
the message of underwater detection excellence using Proton Magnetometers and
Pulse Induction Metal Detectors (Aquapulse).
The newest addition to the AQUASCAN line of underwater detection equipment is
the AQUASCAN DX-300 DIVER HELD MAGNETOMETER.
The DX-300 is a hand-held gradient magnetometer, utilizing fluxgate technology. It
is ideally suited for an array of search applications, both on land or underwater.
Applications
– The DX-300 is the ideal tool for the location of buried ferrous wreck
Wreckage
material.
There are unlimited applications in all types of archaeological wreck
investigation.
It is the ideal diver-operated tool to locate items buried deep in
sediment. It allows accurate mapping of all buried ferrous material prior to seabed
disturbance. It can also detect the presence of some forms of ballast material, which
in many cases gives a magnetic response.
– The DX-300 is also ideal for locating and mapping pipes and
Pipes and Cables
armoured cables buried in sediment. It can detect at burial depths of between 1 metre
and 7 metres, dependent on the diameter of the pipe or cable.
E.O.D & Security
– There are unlimited applications in all types of underwater
investigation for the presence of ordinance, weapons etc.
Salvage
– The DX-300 is a useful tool for the successful recovery of lost items either
in low visibility or where lost in soft sediment. It is the ideal tool to complement
surface operated searching.
The tool most requested by users of boat-towed
magnetometers is a diver-held device to help pinpoint magnetometer targets located
with a conventional towed-magnetometer. The DX-300 fills this need extremely well.
Example of appropriate use of the DX-300
The following is an example of an application where the DX-300 might be utilised
with great success and great savings in time and effort.
A magnetometer target is found with a boat-towed system in 35 feet of water. The
visibility is minimal and, upon examination by a diver, the bottom is found to be flat
sand and no target could be detected within the range of a metal detector. The DX-300
is taken to the bottom by the diver, after the unit is switched on and set to Hi
sensitivity, the diver scans the identified area in a series of straight lines radiating out
from the initial seabed marker and notices an increase in the audio frequency in one
specific direction. Moving slowly in the direction where the audio output of the DX-
300 increased, the diver notes where the peak response occurs; using the range
