This is what i think: I will leave out some other facts about minelab and keep it on the "50 % more power" statement.
Am I a minelab fan? Yes and I want to make that clear upfront. MInelab does make some of the very best metal detectors out there and i am sure they also have marketing professionals who they listen to. It is also Minelab's choice to listen to them or want to use their marketing advice.
I think minelab should have not used their advice in this matter or should have thought it out. I do not bleieve that minelab's marketing department do not metal detect or they would have seen this problem a mile away.
