His Fisher 1212X has plenty of depth and sensitivity but is comeing up short on discrimanation. It will kit hard on steel,Iron,Tin,Aluminum consistently 6-8 inch's down all day long. Now we are in a trashy school yard so we keep finding a bunch of junk. I think when we go again I am going to set his Disc to 8 or 10 since 4,5,6 seem to do next to nothing. I have to admit some tone id would be nice or the ability to completely notch iron,steel and tin right out!!! I guess you cannot get 1 knob simply though and get all that too. I am still waiting for my Bounty Hunter 8400 VLF/TR Discrim etc.... model to arive! If their is one thing I hate about Ebay it is that seldom do you get anyone that sells on Ebay that actualy run's their business like a business! If you are lucky some time that week they will put your stuff in the mail and then over charge you for the mail. I am kind of funny that way if I when on a Monday and you get paid on Monday via pay pal I expect you to get my package in the mail with in 24 hours of recieveing payment not 48 hours not 72 hours etc...... If you are going to do the once a week trip to the post office put it in your add description so people do not expect to have gotten it 4 days after they won! I have goten some things as quickly as the next day while other's are two weeks out etc......
