with all of our modern day electronic advances.......pulse metal detectors have lagged so far behind. VLF metal detectors have come a long way in the last 40 yrs....but pulse is still in the 60's!! Guess the engeneers just aren't motivated. Oh well I'm sure the French or Bulgarians will solve this problem......have you seen the detectors coming out of Europe!! Wow....they are really on the move. Where is the iron rejecting pulse....should be here by now. I'd have no problem paying $1500.00 + for such a machine.........it would truly be the "supreme beach machine" .
