INTRODUCTION.

The AQUASCAN DX-200 has been developed as a powerful detection tool for the diver, providing a solution for a multitude of detection requirements. One major role is to complement the towed magnetometer where solid evidence from the surface survey is met with a flat apparent debris free seabed, investigation by the diver with the DX-200 can readily pinpoint the buried ferrous anomalies.
The system has a selectable sensitivity which in itself can assist in the progressive pinpointing of a target, response is indicated by an audible tone allowing the diver to determine the the closest proximity to a target by the progressive increase in audible tone.

SYSTEM DESCRIPTION

The DX-200 has been designed to utilise the same housing as the familiar AQUAPULSE (AQ1B) range of metal detectors. The system comprises a robust electronic module together with a one metre length detection probe, a slim Bonephone (or optionally Underwater Headphones) and a universal mains charger. Connections are made to the control unit with the same robust underwater Ikelite connectors as the AQ1B range.
The mains charger, Bonephone & Headphones are identical to those supplied with the AQ1B family, this allows existing AQ1B owners to utilise these items on a crossover basis. An internal NmH battery pack gives a minimum of 12 hours operation when fully charged and can be readily topped up at any time without the drawback of “memory” effects.
The system utilises a pair of high sensitivity Fluxgate magnetic sensors with a 600mm (approx 2ft) spacing, these are built into a robust GRP probe together with a pre-conditioning combiner circuit. A two metre polyurethane sheathed cable couples the probe to the control unit via an Ikelite connector. A Low Medium and High sensitivity mode can be selected, this allows the system to be progressively de-sensitised as a target is investigated. The audible output can be preset to be silent or at a low frequency such that a minor change in pitch can be observed, this is how the presence of metallic items are determined. The proportional nature of the audio response allows the object to be accurately pinpointed or tracked as in the case of a pipe or cable. The nature of a response can also be helpful in determining the way an object is lying – such as an anchor or cannon.

The DX200 probe is also available with longer cable lengths, up to 30m. Contact us for a price.
