I recently traded for a F5 with the 11 inch dd coil and after about 18 hours of detecting, I am in love with this detector. It has been very hot and dry with ground like concrete so I have been detecting much less then usual. I am not new to the F5, but I never gave my previous one a fair shake. I bought my first one as a clad hunter and never really tried it at my places where I find older coins. I have used this one at all of my spots and boy am I pleased. I have found both deep coins and masked coins in places that I believed were void of anything good. I have found 10 silver coins at depths up to 9 inches and three Indian heads in some of the trashiest spots I have ever hunted. Last Sunday I found the oldest coin I have ever found in my favorite park and it was where I have hunted dozens of times. In these previous hunts, I have not even found a wheat penny. There are three or four targets evey foot or so. I could not use the pinpoint button because of the density of this trash. Using the big coil was a challenge, but by barely creeping the coil, found this 1875 Indian head between a square tab and pull tab. I will be buying a small coil for this detector as asap. I hunt several places where the FeO meter constantly shows three bars and the detector ground balances around 90. I am amazed at the depth I am getting here. I always try to run my threshold as close to zero as I can and where possible the gain around 85. In some places I have had the gain at 55 and still find myself digging 6 inch deep coins. I also use three tones with the disc set at 15. I hardly ever dig rusty iron and if I do, I usually find a good target close by. This detector is the real "sleeper" in the Fisher lineup. I prefer the controls of the F5 way better than it's cousin the Omega. I have found the performance to be nearly identical between these two fine detectors.
