Many people think the detector is the only one factor that affects the productivity of the search. These people are wrong! The detector operator is as important as the detector itself. The target you are searching for is also important – size, shape, position, metal or alloy type, age and some other factors determine if the detector will get that target or not.
The detectorist shall choose the detector settings – frequency, power, search coil size, swipe speed and so on, according to the expectations he has on the particular site he is going to detect. For example, choosing a very low frequency and/or a large coil for coin shooting is not a good idea. Trying to go deeper for hoards and treasures at high frequency and with a small search coil is also a waste of time…
The detector operator should understand how his machine works. And this is really essential – you cannot just grab a detector, go out and start creating wonders. There are some base rules you have to understand. You have to also make some experience with your machine to stack with it. Experienced users could understand all the signals their machine emits and guess with a very good chance what they have under the coil, without looking on VDI numbers, graphics and digital icons.
Here is a video made by the official Golden Mask reseller – GMD. They made that video to show a customer that there is no anything wrong with this machine, just metal detectors work like that.
