At -3 threshold 8"s same weak audio, at -5 threshold 7"s same weak audio. Now in BP mode different story you get more depth but I will let you guys figure that out. I set the Sen at 80, kept the last G/B I used the machine at and it was 74 and I never fast grab always do a manual. Sometimes I need a little more Pos. G/B then other times. Remember this you must adjust the freq. to quieten down your detector and this time it was F6. Sometimes I have to go as low as F3. Just depends on the noise. First thing you do is G/B then adjust the Freq. and go check G/B again cause it will throw the balance off in a very noisy area. Always remember there are 5 clicks between each number you adjust on the f75 no matter what it is. It does matter especially at the beach and very bad ground.
You would just think I was hyping the F75LTD if I told you the difference in depth. I would not want to be called a Hype stirring guy like Buckeye Brad and some of these other guys

that are telling you the truth when they say the LTD is one Bad AZZ machine. Sorry Brad

I could not resist. We know though don't we.

.
One last thing on the F75LTD. The footprint on the 5" coil and the 3X6" coil when you are in BP mode makes the coil 2 more "s wider. So instead of a 5" coil at SEN. of say 70 it has just become a 7" coil and the 3X6 you get 2 more "s of width also. So if you are hunting the iron and the trash like I hunt turn the Bitch down in BP or you are going to have a tough time in the trash and the iron. In the simi Trash and Iron the larger foot print is a benefit cause you are working with a larger footprint and can cover more ground. So the BP footprint can be a bad thing but it can be a good thing just depends how and where you are hunting.
One other thing my F75LTD runs a lot quieter then my F75 in Dis and All metal. I can't wait to go to Fl and hunt on those black sand wet salt water beaches I hunt. That will be next month in Jan.. You all know the F75 won't hunt on the Black Sand salt water beaches don't you

. Yeah right. More Hype Brad, again I could not resist. I told them all that 2 years ago.
One more thing the Freq. numbers do have a effect on the Dis mode. I really don't think the threshold has a effect on the dis. mode. I never noticed it but I really never tried to do any testing with it. If it does someone let me know will you.

: HH and I am just another HYPE stirring old guy and nobody should believe me. Just check it out for yourself. What I noticed in the all metal mode is like cranking the threshold up on one of my Tesoro's. Sort of like super tuning it.

I have had one hell of a bad year this past year with all this damn Prostrate Cancer and Skin Cancer. can't seem to get away from the damn doctors. Everything is OK now and I can get back out hunting.
