Yep Im the one that was bummed with Fisher because my F75 LTD had the screen snapped off from the handle in the box but hey I got a replacement on my door step tonight just in time to hit my civil war site this weekend. I begin reading the directions and go through modes dying to test out Boost Process. So Im scrolling through all the modes, de, bc, je,etc but theres no boost or cache modes???? I recheck everything and reread everything but nothing. I do the hard reset and keep getting an F on the screen instead of the Le (limited edition). The machine is solid black, has all the decals etc but this is not an LTD!!! So another couple of hours waste assembling, disassembling, and repackaging the wrong detector. I would love to have an F75 LTD that works but if I had it to do all over again I would have bought a Whites V3i just because of the headache. I hope someone from Fisher reads this forum and sees this!
