  • Metal Detector FAQ

    2011-2-10 · For a lot of metallic targets, lying in moist soil causes corrosion, whereby some of the metal will leach out into the soil, causing the target to appear much larger than it really is. When the soil dries out, the corrosion may not affect the detector, which makes the …

  • How deep can a metal Detector Reach – Detector Power

    2020-3-2 · Some metal detectors are trained to detect a fairly basic level of depth. This is determined according to its range. If it is a low range it can detect around 5 to 10 cm while a medium range can detect almost double by reaching between 10 and 15 cm. In the case of the high range they can be up to 25 to 35 cm deep.

  • FAQ''s about metal detectors

    2019-6-5 · A: The sensitivity control on metal detectors is probably the most misunderstood control on the instrument. Sensitivity is usually set to its maximum level and ignored. This does not always allow for maximum operation of the detector. To use an analogy, think of the sensitivity control as the throttle of a car.

  • Long distance Metal Detector schematic | Forum for …

     · 1. Activity points. 70. The limit of a good metal detector is about 30 cm in soil with low mineralisation for 1 Euro coin. The equivalent of this is about 40- 45 cm air drtrction. This is impossible for 90% of the mass produced detectors. …

  • Finding Gold Essentials

  • Can''t Drive Ground Rod for HF Vertical Antenna into …

     · In rocky soil I''ve found that sometimes using a larger gauge, stronger (copperclad steel) 8'' rod can be driven in at an angle, maybe 45 degrees, to successfully push rocks out of the way. A hammer drill does help. An advantage of the angle is it makes the "top end" of the rod lower to the ground so you don''t need a ladder to start hammering.
