Minelab vs xp deus electronics engineering

[Jollyrodger1]

Basic thought of metal detectors are much the same, coil copper wire, how many spirals in a typical coil. I’m trying to learn and educate people very interesting to understand how this work. Now the control board or remote, not the cosemetic looks because minelab has that beat, what truely the difference in the scientific facts if the coil leads the brain , what’s the power difference in the brand, multiple frequencies yes but, how are they different in performance, not what your comfortable with what’s the honest explanations, thankyou electronics experts.
