I own the F5 and think it is a very nice detector. In my opinion it has one of the nicest displays going. Very adjustable with all controls on the front panel and no menu diving. Mike Hillis was known as the F5 guru and wrote the F5 bible. Do a search on Mike Hillis and read up on his tips. He found lots of rings with his unit. The F5 is very good at coin shooting and has a very distinctive high pitch tone. When it sounds off you will know you have found something good. The F5 was my first "real" detector when I bought it many years ago. I sold it after a couple of years but there was something about it that made me always miss it even though I owned higher end detectors. About six months ago I saw a vendor selling new units at a very very steep discount with two coils. Almost half the price of what I paid many years ago so I bought one. My understanding is Fisher had discontinued the F5 and this vendor bought out the remaining inventory. They sold so well that I read that Fisher was going to make another run. I think you will really like this detector.
