The F75 LTD is an extremely deep machine with blazing fast recovery. I've pulled a 1976 bicentennial half slightly past 12" in overturned farm land. It was not a solid silver VDI hit. One thing you have to keep in mind with this machine or any is that if you want deep finds you have to do some mental math to realize that the VDI will fall off with depth. Getting the max depth out of this machine requires knowing the machine well and working in the mild to moderate soil it thrives in. I recently parted with my F75 LTD as I thinned a herd of 9 machines down to just 2. It was my last cut and the one that hurt me most to make. Now I'm down to a V3i and MX Sport, but watch and see if I don't sneak back up to 3 machines in the spring (hello F75 Plus).
