I have a like new F75 that I bought 1/19/15 from Bart @ Big Boys Hobbies. (I have my invoice)It might have 20 hrs on it. Absolutely no problems or flaws on detector. It's had a coil cover and the neoprene display/battery compartment covers on it since new. It comes w the 5" coil, and the original box and owners manual. Like to get $850 for it.
