The reason I sold my 6000 was I got sick of digging foot deep holes for a pellet. my back is not the best anymore....The gold I found with the 6000 was mostly 1 to 6 inches deep, from 0.01 to 2 grams in the Triangle, Hill End and up North Queensland. i hope this E1500 will also find that gold at little depth. Next week I will be going to flogged areas where I found a lot with my 4500 and when that finished I found the little left over ones with the 6000. Hope the E1500 will do well.
