The UWM 40 is designed to search for metal objects on land or underwater. It detects ferrous and non-ferrous metals and also alloys. It indicates the size and conductivity characteristics of the detected objects: large and highly conductive objects will be indicated by a tremolo signal added to the audio alarm. This permits the diver to determine while searching whether a signal is from a larger object worth recovering or from.

As a fully-fledged UW metal detector in industrial quality the UWM 40 captivates with its good detection range and its compact, handy design. It detects all metals. For determining the area of application: objects, small or large, which can be recovered with basic tools. The limit of the detection range depends on the size and location of the metal objects as well as on their composition and the local search conditions.

Key Features

  • High detection range
  • For land and underwater
  • Detects all metals
  • Audio object-information
  • Suppression of signals from small objects
  • Clear, audio signal
  • Permits easy locating
  • Can be used in saltwater


Despite its small size and search head this small and most simple to use underwater metal detector offers an impressive detection performance and an high resolution of small metal objects buried closely to each other. The UWM 40 detects ferrous and non-ferrous metal and alloys. The limits of detection range depend on the size, distance and kind of metal object to be detected. Small objects such as coins may be detected up to 25 cm distance while large objects can be located at correspondingly larger distance.
The audio signals from the UWM 40 permit differentiation between large and small objects. This permits the diver to determine while searching whether a signal is from a larger object worth recovering or from unwanted scrap.

Mode of operation

The detector applies the dynamic pulse induction principle which is advantageous for operation in saltwater. Short magnetic pulses are transmitted through the search head. These short magnetic pulses induce eddy current in conductive objects. The objects respond by a magnetic signal which is detected by the device and converted into an audio signal in its single sided head. The audio signal increases in frequency as the detector’s search approaches the metal object. This helps the diver to poinpoint the target object. If the object shows high conductivity a tremolo signature will be mixed into the audio signal.

Constructional features

It consists of a square shaped search head with joint, which is flanged to the detector handle containing the battery compartment and socket for the headset. The detector is switched on by half-rotation of the handle. The sensitivity can be adjusted by means of a sliding adjuster at the search head joint.  For land use, the extension tube is screwed on.
