3. VANN When you want to avoid detecting ferrous metals you can turn the iron switch off and enable the device to eliminate these metals and not produce a warning tone NOTE Many metals considered to be trash may not produce a ferrous metal signal For example pull tabs may be sensed as a non ferrous metal by most detectors because their signal is very similar to that of gold CONTROLS MINERAL MODES Mineral Modes If you are searching on high mineralized ground extremely salty soil wet beach sand wet plowed land or highly magnetic ground conditions you may not be able to ground balance the device In such a case first turn the On Off knob to mineral 1 If the device is still getting noise turn it to mineral 2 or mineral 3 This will eliminate the noise and false signals caused by mineralization However you may experience a decrease or fading in the Mineral signal obtained from certain metals at maximum depths ainera As mentioned before especially on grounds with high iron content such as wet salt water beach sand and wet plowed land it is recommended that you search in mineral 2 or 3 mode bring the iron discrimination to maximum level and turn the iron switch off SIGNAL AUDIO BOOST SIGNAL AUDIO The signal audio boost switch boosts the sound of weak signals received from small or deep metals making it easier for you to detect those uncertain targets At position 1 the booster is off At 2 the signal audio will be
