Underwater Metal Detector Elsec 5000

Enhanced Sensitivity Using the pulse induction technique, the Model 5000 is able to offer a much higher level of sensitivity than most other metal detectors on the market today.  It detects both ferrous and non-ferrous objects, even in high concentrations of metallic deposits, at considerable distances.

Our Elsec 5000 is easy to control, diver friendly being nearly neutrally buoyant. Strong, Non-corrosive Construction Each Model 5000 is tested to a depth of 200 meters and should be able to operate at greater depths. It is manufactured using PVC high-pressure mouldings and marine grade stainless fasteners so that it will not rust.

Underwater Metal Detector Elsec 5000

Rechargeable Batteries The Elsec Underwater Metal Detector incorporates rechargeable Batteries, which allow continuous use for over fifteen hours.  A solid state indicator lets you know how much 'life' the batteries have left.

Three Methods of Indication When a metal object is located, attention is attracted in three different ways: a ten step led scale and a variable frequency bone conductor earphone. Reliability Elsec has used the very latest electronic components in the manufacture of its Underwater Metal Detector to ensure first class reliability and ease-of maintenance.

Our Divers:

MMC Divers can provide an EOD Superintendent and UXO dive team to assist in the identification of a potential UXO (pUXO) – An anomaly identified as UXO by geophysical survey and data analysis but not yet visually identified by a UXO professional, the Elsec 5000 has been successful on numerous occasions with our competent teams.

It is generally accepted that 10% of all aerial bombs and 30% of incendiary devices dropped during the WW2 failed to function as intended and a certain amount are possibly still buried in the local geology or present on the seabed.

MMC's team of experienced divers also includes CSWIP 3.1u, 3.2u and 3.4u qualified inspection personnel. Our divers all hold the relevant commercial diving and CSWIP and HSE approved certifications enabling them to support the delivery of subsea calibration and measuring survey services.

Subsea inspection services include:

  • UXO, PUXO identification.
  • Above and below water inspection of structures and facilities.
  • Detailed survey, inspection, investigation and assessment of subsea structures.
  • Subsea cathodic protection and ultra-thickness inspections.
  • Scour, geological sea bed and river surveys.
  • Emergency call out response for infrastructure inspection.
