Bought two F75 ltd fisher metal detectors, one for him and one for me. I have been a whites user since 2007. I owned a minelab explorer she but traded it for the mxt pro which I love. I've seen the f75 in action and suggested to my buddy up north that he would benefit from it because it is such a hot machine and only weighs 3.5 lbs. Due to his generosity he bought me one so I could learn it and teach him how to use his. Any pointers from you pro users of this machine will be appreciated.
