The Freq shift and the Threshold are 2 of the most important features to quieten down the noise of the F75 and now my F75LTD which I just got yesterday evening. Naturally it is raining like hell and can't even get to my 9.5" dime on edge in the yard to test this machine out. My F75 and Shadow X5 tare that dime up better then any machines I have got. Then to the lake to dunk the coil in the water to see if it leaks. BTW when I hunt the wet black Sand salt water beaches in FL, Tx, the threshold and the Freq shift are verry inportant. Without them on the F75 I could not hunt those beaches. I love it when they say the F75 won't hunt on Salt beaches and it won't get any depth, or is not suited for them. that cracks me up. 
Anyway just thought I would let you know about the mistake in the manual. I do have a question though. When I turn the machine on I get the letters L E comming up on the screen and then it fades out. What does L E mean. Maybe Limited Edition.
