Metal detector professionals believe the electronic circuit board could be the key to how deep a metal detector will discover finds.  A good electronic circuit board will definately provide an edge, however it does not seem to be the key secret to deeper finds. Looking at a metal detector like Nexus Ultima  with a 20 inch search coil it shows a remarkable depth in comparison to metal detectors with smaller search coils.  Tuned at 5 different frequencies, it reaches a depth of even 3 meters under ground.  Having tested this metal detector it brought a new idea about what I previously believed to be the truth.
