Got a Whites GMT on the way,,,,,, just starting a new facet in my MD hobby,,,,, have been diggin coins and Jewlry for about 18 months now. Have done well enough to add an ETRAC and now the GMT to the arsenal,,,,, always looking for a hint or help from those who know how it's done. I have rivers,, creeks and tailing piles to go thru here,,,,,,,,,
