F75

QUESTION FOR TOM

I ENJOYED YOUR DVD I THOUGHT YOU DID A GOOD JOB. I AM WONDERING IF YOU CAN HELP ME WITH MY F75 UNIT. I DETECT AT A LOT OF OLD CELLAR HOLES IN NORTH EAST WERE MINERALIZATION IS VERY HIGH. WHEN I AM DETECTING I WILL HIT SOMETHING WITH A REPEATED SOUND WITH A GOOD READING AND WILL PULL OUT A PIECE OF JUNK . I USE SENSITIVITY AT ABOUT 89 DISC AT 6 AND DE MODE NO MATTER IF I LOWER SESITIVITY IT IS STILL THE SAME.THANKS

Hmmmmmm. What do you mean by a piece of 'junk'? Is it ferrous (iron) or non-ferrous?

HELLO


I WILL PICKUP SMALL IRON PCS DEEP ALSO SOME PCS OF OLD METAL .THE REPEATED SOUND IS STRONG AND NUMBER OUR WERE YOU SHOULD BE PICKING UP A COIN.THANKS

Sounds like the area is littered with steel......... which is an alloy. Normally, I don't recommend this; but give the 'bc' mode a try.
