STINGER 2 User’s Operating Manual ______________________________________________________________________ Made in Bulgaria 1
In order to use the device for a maximum long time and without problems, as well as to be able to use all of its options, please read carefully the whole instruction manual and observe the directions in it. The standard set of STINGER 2 comprises: - searching frame 1x1m (or 1,20 x 1,20m.); - monitor unit with built in accumulators; - charger for 220 V; - charger for 12 V; - detailed instruction manual for operation.
position of the coil to be parallel to the ground surface. Don't over-tighten the plastic bolt and nut to not damage the threading of the bolt! The coil cable is wind up tightly around the bearing rod and is switched to the terminal of the monitor unit. Upon switching of the cable of the coil to the monitor unit, tighten the well the metal nut of the coupling to the terminal of the box.

degree of mineralization of soil. For example, in order to understand how strong is the signal from the soil on a definite location, one can lift the searching coil in the air and the device to be nullified with short pressing of "ON – OFF / CLEAR". Then, the coil is brought close to the ground surface and one can se opposite „Level“ what is the indication of the signal of the soil.
sound. This is done with change in the parameter "Thresh. For this purpose, through the buttons "◄ and ►" desired value can be selected from „0“ to „20“. The lower the value of „Thresh“, the greater the sensitivity of the device. For instance, if at a balanced device the constant signal from soil is "1" and we have chosen for "Thresh" a value of "1", then a sound signal is going to appear when the general signal becomes greater than "1".
shorten the sweeps until you just barely get a response at one spot. The target will be directly below the coil center at this response time – fig.3 fig.3 Upon short pressing of the „MODE“ button, the indications of the discrimination ID1 and ID2 turn on, as well as the intensity of the signal located, in digital or in graphic appearance. In graphic form the indicators may show positive or negative levels, respectively, increasing to the right or to the left from the dividing zero point of each of them.
After each change of some of these 3 parameters, the device automatically restarts in order the respective settings to be loaded according to the selected values. „rejF“ (0 – 15) – through this parameter the device can be adjusted to decrease its sensibility to smaller objects without losing its sensitivity to bigger ones. This has its effect only in the mode with capital letters – AUTO DISCR. The greater the value of „rejF“ , the smaller the sensitivity to smaller objects.
Upon localization of foil, aluminium and unstained iron, ID1 and ID2 have their negative values, and both of them have great positive values express when the nonferrous metal is pure, without admixtures and alloys – gold, bronze, copper, silver. Upon localization of highly stained iron, ID2 has great negative value, for example -15 -20, and the indication of ID1 is around zero or +1, +2. They show that there is no sense this signal to be checked where it comes from.
the symbol „_―. If there is a difference in both levels balance of the device should be performed through „POWER / CLEAR“. In the discrimination modes, with the pressing of „SELECT“, the following settings can be selected: „Low tone“ - (1, 2) – 1 is low tone turned off, and 2 is low tone turned on. „olD1“ - setting of the position of zero for the indication of ID1 – it can be moved to the left or to the right along the scale. I. e.
is done as follows: the „STORE“ button is pressed and held and to the searching coil a definite type of nonferrous metal is approached, the indicators for the type of metal „ID1“ and „ID2“ show the type of metal and against „accept / ACCEPT“ a definite figure is depicted (as per the type of metal) - for example „accept: +12“.
In the „auto discr“ / „reject“ mode the device memorizes only the purity coefficient ID1 of a metal, and in the “AUTO DISCR“ / „REJECT“ mode it memorizes both coefficients – for purity ID1, and for magnetism ID2. The display shows an indication, for example: „R: -9, -28“ (corresponding to „ID1 = -9“, and „ID2 = -28“). In this case the device will eliminate signals from a located metal, only if both memorized coefficients coincide. I. e.
items or under active stones and highly mineralized soils. In this case, if, for example, an object (stone, ceramics or some iron) has been memorized, with own signal of „-28“, the device will not react to any signals smaller than „-28“, and each signal greater than „-28“ will be registered with sound, as the objects „with more positive signal― (from „-27― to „0“) will be signalized with a low tone, and all positive ones – with high tone.
be performed in this mode is to press „ON – OFF / CLEAR“ for short, as the searching coil has to be close to the ground surface, at the distance at which one will search. In this way, the signal from the soil is perceived as zero and each change provoked by a metal object will provoke a sound signal with high or low tone, according to the type of metal.
The accumulators' status is shown on the first row on the right as per cents of the capacity (0%-100%). When the capacity decreases below 0% it will show ―Low bat‖ and if fully charged batteries or if using external supplying block with higher voltage it will show ―+++‖. The charging is automatic and begins when the device is SWITCHED OFF and you plug the charger into the charging jack of the back panel of the device. The jack cage is ―-‖ and the middle terminal is ―+‖.

The Manufacturer (trader) does not bear any responsibility if you use the device in violation of the law, on archeological or forbidden for search places as well as on private property without the knowledge or the permission of the owner. Protect the environment and always fill back in the holes you have dugged out! 7.
any moisture or water from entering the control housing and never allow the cable connector to become submerged in water. If working in or near water, or if there is a possibility of rain, use a protective weather resistant pouch or plastic bag to cover the control housing. Make sure it can "breathe" in order to ensure against condensation buildup inside. After each use, clean the detector with a soft cloth to remove dust, moisture, or other contaminants.
