Professional metal detector with metal discrimination and a detection depth of 5 meters (17 ft - up to 6 meters (20 ft) with 2x2m cable coil). Pulse induction device with microprocessor-controlled metal type indication - appropriate for the search after gold and precious metals (silver, platinum) - precision made in Germany! Pulse AR III has decisive advantages in comparison to conventional metal detectors: pulse induction technology with metal discrimination undisturbed search in mineralized grounds and salt water 5 different search coils (depending on equipment version) with auto calibration high sensitive reaction to gold and other precious metals convenient search and easy handling pulse-ar-3-searchframe Up to 6.00 m (20 feet) depth performance: Only with our big search coil (2x2 m cable coil) and pulse induction technology it is possible to locate larger objects in a depth of up to 6.00 m. In comparison, conventional detectors only allow a search depth of at most 2.00 m. Spacious search areas: Solely the search frame (pulse induction technology) enables a comfortable and swiftly exploration of large areas. Example: the scanning of a surface area the size of a soccer field will only take 3-4 hours, while the search with a conventional device would take several weeks. Undisturbed searching: Most of the mineralized grounds contain stones with metallic characteristics which therefore are displayed as metal objects by the majority of detectors. These grounds and salt water are no problem for PULSE AR III - with the Reset-button (automatic zero balance) most of the disturbing mineralized objects (which can lead to errors) will be neutralized. Image description Image description Metal discrimination for medium-sized and large objects: The PULSE AR III was also developed for the search after large, low lying metal objects and is especially suitable for professional seekers who want to search in wide-ranging areas in a speedy and efficient manner (under avoidance of scanning small parts, e.g. rusty nails or bottle caps). Automatic adjustment: PULSE III works with a variable search frequency between 1200-1600 Hz, therefore the application of all search coils is uncomplicated. The various search coils for the PULSE AR III can easily be cable-connected to the electronic unit, because a special switching mechanism controls the coil electricity and adjusts the adequate search frequency automatically. To discriminate various kinds of metals the PULSE AR III is equipped with a microprocessor-controlled conductibility registration, so that metals like iron, gold and silver can be separated from each other and visualized on the display. Electronic unit The electronic unit is installed in a high-quality solid box. The front is equipped with 4 appliance elements and a display. (1) MODE = The MODE adjusting knob can be switched to 4 positions: OFF = The device is switched off BATT. = Battery check-up – accumulator battery-condition. When accu is loaded, needle stands at 100 and more DISC = Discriminator - search mode with discrimination of metal kinds * ALLM = All-metals search mode without discrimination of metal kinds** (2) RESET = Automatic zero balance through Reset-button. Device will be adjusted to the accordant soil. (3) FREQ. = Fine tuning for a solid control sound (4) VOLUME = Volume control (5) Right-hand LED = The right-hand LED serves the purpose of discrimination in DISC mode; the LED flashes when the optical indicator appears in the ALLM and DISC mode. The left-hand diode reflects the frequency pulse. * DISC In this search mode the discriminator comes into operation. Thereby an optical and acoustical discrimination takes place. The different metals will be signaled through varying tones and conductivity values. Examples of differential conductivity values: light metals (e.g. aluminum) 20-40 copper 40-60 gold, silver, platinum 100 and over ** ALLM All metals will be visualized without discrimination acoustically and optically through the value number (the metals will not be tested for their conductivity). This position has the advantage, that you can detect with highest sensibility; through the value number one can evaluate the depth of the object. The lower the value number, the deeper the metal object is hidden. The shape of the object can be identified as well. For the PULSE AR III we offer different waterproof search coils, which can be cable-connected to the electronic unit easily. An additional adjustment is not necessary. By using the appropriate search coils (25 cm or 45 cm) smaller and medium-sized objects can be located. To attain an ideal search result the adequate search coil should be selected. 25 cm search coil The 25 cm search coil is the standard coil of PULSE AR III and primarily suitable for the search after small metal objects. 45 cm search coil Useful for the search after small, medium-sized and large metal objects. Also very convenient for a search process without interruption. Cylindric coil Through its dimensions of 5 x 20cm appropriate for the search in wells, narrow excavations and underwater. Furthermore very helpful for finding micro-objects. 1 x 1 m Searchframe Preferably used for the deep sounding after medium-sized and large metal objects. During the search you should hold the searchframe between 20 to 50cm over the ground. The higher the distance to to soil the less smaller and medium-sized metal objects are displayed. Intensive magnetic fields, particularly in the proximity of high voltage masts, can cause disfunctions, which can be neutralized by using this compensation probe.
