Metal Detector CZ21-10
The underwater metal Detector Fisher CZ 21-10 is versatile, with its help it is possible to conduct field excavations and dive into the unknown sea expanses to search for real lost treasures to a depth of 76 meters. The metal detector works on two frequencies of 5 khz and 15 khz, which allows it to cope perfectly with the detection of small items, and find deep deeper goals.
Features Fisher CZ 21-10
The ladder T-shaped rod is designed in a special design to facilitate the weight of the detector. The upper bar is made of white-colored aluminium, the lower rod is made of impact-resistant carbon. The way of connection of rods - with the help of only one spring button deserves special attention. This method of fastening allows the diver to quickly change the geometry of the device. Adjustment under the height is made by means of numerous apertures on the top rod. The armrest with the liner of porous plastic is very convenient, the hand is a little buried in it and perfectly fixed. The large handle with a special non-slip coating gives the whole structure additional comfort.
Fisher CZ 21-10 is equipped with a DD reel made of durable plastic, designed to take into account the possibility of conducting search operations at great depth. The unique design of the sensor allows to avoid false signals, to identify the target perfectly. When immersed, the control unit is placed on the upper bar, and during field work it can be easily hung on the belt, reducing the total weight of the detector. The plug of the coil is not socketed, as only this coil is suitable for deep immersion. The same situation with headphones.
Three modes of Operation Fisher CZ 21-10: Silent Dynamic with discrimination, dynamic mode "All metals" with a threshold tone and a static mode Pinpoint, which is responsible for locating the target with an accuracy of several millimeters.
Since Fisher CZ 21-10 has no visual identification, the latest developments have been applied to improve the quality of sound identification. The volume scale is divided into two sectors: in the sector from the first to the fifth division from any found object will be amplified volume, and in the sector with the sixth to tenth division of large objects sound will remain in the same volume, but the response from Small objects and deep lying will be intensified. Trehtonalnaja sound identification: Low tone for iron, medium and high-on ferrous.
For discrimination Fisher CZ 21-10 meets the Twist DISC. Adjust the level of discrimination in silent mode follows the potentiometer positions from 0 to 6. To switch the metal detector to the "All metals" threshold mode, use the AUTO TUNE mark.
In Fisher CZ 21-10 consistent discrimination, so it is necessary to exclude from the search unnecessary items as well-sequentially. At first we exclude iron, then the trifle of non-ferrous metal, that is why it is most effective to work at the lowest level of discrimination.
Sensitivity setting is made by SENS handle. The higher the sensitivity level, the deeper the device sees. The same potentiometer is used to charge the battery level.
The ground potentiometer is responsible for the soil balance. You can adjust the device to the ground using the pinpoint mode or in the "All Metals" mode.
The Pinpoint button moves the metal detector into the "All Metals" mode, which determines the exact location of the object. The more intense the sound, the closer you are to the cherished goal.
