"STINGER" is an impulse metal detector with an LCD – Display, digital and graphical presentation of the level of signal and parameters of discrimination and working modes, as well as of the state of temperature of the storage battery; Fully automatic balance to ground conditions with memorizing and adapting to the level and parameters of the background of soil and their elimination by the general signal.

the conditions of the soil through pressing and holding of the "MODE" and momentary pressing of "CLEAR GND" - Button "DISCR" – serves for turning on and off of the discrimination modes. 1. Setting and way of work: Seeking frame is assembled and is placed on the ground paying attention to the range and there don't have to be any metal objects.

"FIX“ are static modes of seeking, i. e., the device constantly reacts to a metal located within the range of the coil. They are suitable for localization of the exact place of an already fixed metal, and one may constantly work in this mode. Fastest one is the "FIX0"...

4.Setting up the working parameters in “DISCR” mode “STINGER” has 3 discrimination modes - “DISCR.1”, “DISCR.2” and “DISCR.3”, that are chosen by pushing the “SELECT” button, until the arrow points the discrimination indication - 1 line and the “DISCR”...

When discrimination is on, besides the signal strength two more values light up C1 and C2, which when a ferrous (magnetic) metal is registered have negative values , and in case of a non-ferrous (non-magnetic) metal – have positive values. “C1” is the value for chromaticity of metal, and “C2”...

The balance indicator “I - I” regarding the soil background lights up on the 1 line at the right side and shows if the device is balanced when the signal is missing. When the device is balanced and there are no metal objects within the reach of the antenna, the indicator should have two equal levels to the right and to the left of the “...

sound signal. In this case, the values of C1 and C2 should be observed, and thus the operator can make a conclusion regarding the type of the metal. -In the “DISCR.3” mode the signal is analysed and in case of change, it is calculated what part of it is a result of the overal soil background and to what extend it is a result of the impact of another object.

For adaption to the soil press and hold the “CLEAR GND” button. On the first row of the display you will see “Get ground” and the device will make a continued sound for adaptation start. After that you must bring closer and then move away the search coil to and from the ground surface within the range of normal searching distances, 5-20 cm for instance.
Best results are received when the soil is dry. 7.Charging storage batteries and indications for their status. “STINGER” has a built-in storage package 18V/2,3Ah, which is able to provide 10- 20 hours of working process without any interruption depending on the chosen power and the type of the used search coil.

“+” and “-” because the use of other chargers or adaptors may lead to irretrievable damages in the batteries! Possible problems during exploitation of “STINGER”: 1.When switching it on you can not hear a sound, there is no information on the display, no indication that the device is switched on.

the presence of some kind of dirty like dust or moisture to clean the terminals with cotton- wool and alcohol. If you can not solve the problem contact the service-station (office) of the company manufacturer or the local distributor. 4.The device works only with headset and when working with amplifier you can not hear a sound.
