Underwater metal detector

The UWM 20 is intended for use in the hobby sector and also in progessional fields of application. The UWM 20 is nused primarily for the detection of small and medium-size  metal objects which the diver can recover without great effort. The detector detects ferrous and non-ferrous metals including gold and silver. Thanks to its circular search head, the UW scanner offers a larger detection range than the UWPP 10  with its rod-type sensor. The range wiithin nwhich metal objects may be detected depends on their size, location and material as well as also on the conditions for detection. 

The UWM 20 underwater hand sensor applies a microprocessor controlled pulse-induction process (PI). Weak magnetic pulses generate eddy currents in the objects being searched for; these retroatc on the sensor as a magnetic echo. This response signal is converted electronically into a vibration alarm. The digital PI system permits the detector to be used in both, freshwater and saltwater. As a result of the static mode of detection, deductions can be made on the size and depth of the detected metallic items.
