This small machine is not "small" at all. Excellent nonmotion detector! And i mean EXCELLENT! Everything what operator need is here. No comfort, but excellent for turn On and go prospecting. It is equiped with standard Isocon coil (approx 20cm), need only one 9V battery and i must say good quallity 9V battery really last very long. I used alkaline Varta battery and it lasted almost a week !!! Every day 3-4 hours on the field. Excellent!
Main trick at this machine is to rise treshold to audible level than lower coil to 15cm from soil surface and push retune button. Release retune button and lower coil to 5cm from soil. Audible treshold will be present all the time but than sensitivity is great! Also audio disrimination works very good.
