- Page 4 - Button "DISCR" – serves for turning on and off of the discrimination modes. 1. Setting and way of work: Searching frame is assembled and is placed on the ground paying attention to the range and there don't have to be any metal objects. The cable is sub - connected to the device.
- Page 5 the device works with different searching coils or frames - " Prof1" – program for small round coils – 28cm. 36cm. 45cm. or "Prof2" – program for searching frames – 1x1m or 2x2m. - 3rd row to the right – threshold of sound, level after passing of which a sound appears - 4th row to the right –...
- Page 6 depicted of the level for more comfortable tracking of the changes in the signal. Indicators can show positive or negative levels respectively increasing to the right or to the left from the dividing zero point of each of them. The indicator on the 2nd row is indicator of the momentary signal. At a "FIX" mode it repeats the indicator of the general signal.
- Page 7 the parameter "TRSa". For this purpose the arrow is moved through "SELECT" to be against „TRSa" and through the buttons "_ and _" desired value can be chosen. For end you press "SELECT" and the arrow goes down again on the 4th row for choice of "FIX" or "MOV" modes. The lower the value of „TRSa", the greater the sensitivity of the device.
- Page 8 “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 - 1st line and the “DISCR” mode should be on. 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 –...
- Page 9 C1 and C2 can have different values if ferrous and non-ferrous metal is present within the coil range. The values C1 and C2 appear only when metal is detected, and when the signal is missing , “TRSc” and “TRSd” light up in their place, as: “TRSc”...
- Page 10 right and to the left of the “-” symbol. If there is a difference between the two levels the device should be balanced again, by pressing the “CLEAR GND” button. The level of the two columns of the balance indicator shows also the power of the signal from the soil.
- Page 11 ferrous metal is detected, with its own coefficient, more positive than that of soil. For example if the signal from the soil is - 7, and that of metal is - 3, the device will make a 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.
- Page 12 the soil. That is to say the bigger the object the deeper it is buried in the soil and the harder it is to be discriminated. Smaller coils have better opportunities for discrimination. 5. Balancing towards the soil background in discrimination modes. For adaption to the soil in “DISCR.2”...
- Page 13 If the soil signal varies in wide limits a constant restarting of the soil balance is possible. In that case you should increase the acceptable tolerance of adaptation as you increase the parameter “ggt1”. In “DISCR.2” at the 2d line “ggt1” will light up. “ggt1”...
- Page 14 When locating a metal object in the soil during search in discrimination modes the device makes a short sound with one frequency. That makes it harder to find the exact location of the object in the soil than it is with a sound with changing frequency.
- Page 15 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.
- Page 16 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. It might indicate for: -storage batteries are dead (usually after a long period of time).
- Page 17 - problems with the coil cable – disconnected conductor, a shot circuit or bad connection in the coupling. It is possible after continuance work and many times of switching on and off the cable's coupling to the jack box the contact between them to be destroyed.
- Page 18 dead quickly. Usually that happens when the batteries are really old and need replacement. Contact the service-station (office) of the company manufacturer or the local distributor for change of the storage batteries. The Manufacturer (trader) does not bear any responsibility if you use the device in violation of the law, on archaeological or forbidden for search places as well as on private property without the knowledge or the permission of the owner.
- Page 19 _ Sweep the search coil carefully, especially when using around rocks and building foundations. Avoid hitting the search coil against hard, solid objects and surfaces. _ Keep your search coil slightly off of the ground during the sweep, especially when using in gravel or hard, rocky dirt. _ Remove and clean out scuff covers periodically to avoid buildup of mineralized dirt particles which will affect performance.
