I've been looking for a 5.75,and had hoped to find a used one. Now, I think I'll back off and stick with the stock coil and the 3 by 18 clean sweep..I was kidding around on a different post about Tab Dog and trash in the ground. That does not seem to be that much of a problem where I have been hunting...I am amazed at what he digs up..I only have one site I would consider trashy, and it has about a pound of aluminum cans per square foot covering (possibly one known good ring) the ground.If, I had to dance in ,among trash, I can borrow a four inch coil for my Silver and see what it does. I use the stock coil and am satisfied it works well in masking situations..Odds are that I am wrong, but to pay $65 and a 1 oz Silver round (this is what I offered in WTB) to separate some coins from trash??? Will just let it slide into the far reaches and hope no one calls me to make good on my offer...I would suggest a 3 by 18 clean sweep coil for the V..You can cover an amazing area in a short time..I think the point here ,is not to go off swinging like a wild man.Be low, slow and systematic, and you will start running a rack. Back in the 60's, he who covered the most ground, got the most goodies..That still holds true....My 2 cents, cordially Nad
