I started with a at pro,now have a xterra 705.wanting more depth,looked into a e Trac and always liked a fast detector,just heard the f75 was noisy.well,I was wondering if that's changed from what I hear,and even though I'm a coinshooter overheard the f75 was no slouch in that department.I' live in western Pennsylvania and would sooner have a light deep fast detector than a slow deep heavy one.any help from experienced owners,I'm ready to buy something.l
