Just got my first two hours on the F75 gold model Fisher put out for under $600. I'm a long term Tesoro user with my primary machine being a Tejon. I am impressed with the F75, the weight and balance of the machine is good, depth in discrimination mode is every bit as good as my Tejon, but the Tejon will still blow it away in all metal, but I expected that. You're not going to beat a true threshold based all metal machine with computer. Target separation and recovery speed of the F75 is much better than I expected, it will run Monty's nail board just fine even in DE mode. EMI is more than I expected but I can deal with that. Away from EMI sources the F75 is very stable, even at full 99 gain. I'm sure it will take a good six months or more for me to learn this machine, but so far I am happy with it. My only real question with it is how do you get the coil cover off to clean under it? I watched the YouTube video on cover removal but I don't see the tabs mentioned in the video.
