In common with the developments in other uses of metal detectors both alternating current and pulse systems are used, and the design of the coils and the electronics has moved forward to improve the discrimination of these systems. Some metal detectors are waterproof, to allow the user to search for submerged objects in areas of shallow water. These time differences were minute, but the improvement in electronics made it possible to measure them accurately and identify the presence of metal at a reasonable distance.
The practice of examining stools is messy and unreliable, and may raise anxiety levels when the coin is not seen to pass. Despite parents of children with proven abdominal coins claiming that every stool was examined for a coin and none found, six of 12 children who returned a week later no longer had radiological evidence of coin presence.

You can also replicate this above ground by placing a coin on the surface and then placing a couple of thick books or 2×4 boards next to it. Then place nails on the books/board above the coin. Now let me be clear in saying I am not throwing a blanket statement onto all experienced metal detectorists. There are many who do like to use bench tests to draw conclusions. Doing a quick Google image search for “nail board test” will bring up a popular test created by a seasoned metal detectorist named Monte. Old coins are what treasure hunters and coin shooters strive to find.
The factory preset modes are excellent, but you can tweak its advanced discrimination capabilities to suit you. You’d expect good things from a machine of this caliber and it doesn’t disappoint.
