some Russian guy can get the same result with another detector where it sees the coins, when the iron is longer than the coil.
Zemleroyk tells in the video that the trick is well known and detectorists should know the nature of it:
If iron target is longer than diameter of a coil used in test, this iron object do not exist for metal detector. Should iron be shorter than coil diameter, it becomes available for metal detector and therefore results could be veeery different
Do not be tricked by merchants and their tricks (sorry cant post the video link)
