Principle of Operation ® The UWEX 722 C works on the Ebinger pulse induction method which can also be applied in conductive salt water. In such case the delay adjustment needs correction (see page 14) ___________________________________________________________________ © 2005, Ebinger Prüf- und Ortungstechnik GmbH.
Page 12 ® Operations Manual UWEX 722 C _________________________________________________________________________ Short magnetic pulses, emitted by the search coil generate an electromagnetic field around the search head which induces eddy currents into conductive objects (i.e. metal) being within the reach of the detector. Fig.
Page 13: Main Characteristics
® Operations Manual UWEX 722 C _________________________________________________________________________ The main advantage of the pulse induction method consists in the possibility to exclude the reading of interference with short responses signals by a delayed activation of the receiver. Interference from conductive soil, salt water or small metal scrap, i.e. nails or wires, can be strongly reduced by a decoupling in time.
Page 14: Constructional Features
® The UWEX 722 C is a battery operated, pressure waterproof metal detector for underwater and normal land use. It consists of a search head with joint, which is flanged to the detector handle containing the detector electronics and the battery compartment.
Page 15: Putting Into Operation
® Operations Manual UWEX 722 C _________________________________________________________________________ Putting into operation For standard underwater use the detector may be used in its short version. For normal land use or when working in underwater vegetation the extension rod can be fitted to the threaded end of the detector handle if the slope is inserted into the extension rod.
Page 16: Testing Before Use
Testing before use ® Take UWEX 722 C out from its carrying bag. Unscrew handle. Insert 9V battery watching correct polarity as indicated by markings. Refit handle. To extend detector use extension rod. Rotate handle clockwise into ON position with white dots matching and set sensitivity knob to required sensitivity level.

® Operations Manual UWEX 722 C _________________________________________________________________________ Pic. coarse adjuster for sensitivity inside battery compartment Using the detector To inspect an area carry search head in scanning movement flat and parallel over ground. Make sure that searched strips overlap and avoid dead spots. The detector operates on a static mode showing metal objects by an audio alarm as long as the search head is held over a detected object.
Page 18: Suppression Of Interference
® Operations Manual UWEX 722 C _________________________________________________________________________ For pinpoint location of shallow buried metal the search coil may be used vertically over the signal area. From experience the detection signals can be interpreted in the right way. A small metal object buried next to the surface will cause a short but intense signal.
Page 19 ® Operations Manual UWEX 722 C _________________________________________________________________________ Pic. Delay adjuster version until serial no 436 Turn upper trimmer marked 'Z' (approx. 3 - 4 turns) in clockwise direction to increase the delay, which reduces interference signals from saltwater and scrap metal.

Battery change If the device is not used for a long time it may occur that the two O-rings beneath the handle stick to the surface and the handle only comes off after jerky anticlockwise rotation.
