Today I took my new F75 out for the fourth time and some of it's abilities came shining through. First, it is a very deep detector. If in an area with no trash, it will go as deep as any detector made. Where I think it shines is moderate to trashy spots. It is a very fast responding detector. I have never used a detector that will sound off on targets close together like this detector. This morning I got a high tone that was mixed with mostly medium tones. The DD coil allowed me to start probing the target from all angles. After checking the target from four or five angles, I decided that there was something good directly next to something bad. I finally got a pinpoint on it and it read 9 inches. From about 8 inches comes a 1953 roosie dime. For giggles, I dug the close target and found it to be an older beaver tail that was 3 inches away and almost as deep. This detector is FAST and the combination of the fast response time and dd coil, it could separate these two items. I am impressed that a big coil could do this. I have read that a disc of 5 or less automatically runs the program in a high gain and this feature is disabled above 5, but below some other number that I can't remember. I generally like to run a low disc and listen to the tones so my settings will always be either 5 or 6. I played with these numbers while I checked targets and there is a big difference between the two. When I ran a disc of 5, the detector got real jumpy and a setting of 6 caused it to settle down. Now for the experts. I don't think I lost alot of depth by running at 6 compared to 5, but I am new to the F75. What are your opinions on these settings? When I run at 6, I can run my sensitivity higher than 80, but I have to lower it when I run it at 5 to get it to settle down. I guess my ground is bad as my GB is almost always in the high 80's. I am learning this detector, but it is producing for me before I even have it figured out. I have found silver coins ever time I have used it so I have to be close to being "on to it" . Thanks R.L.

A Couple Of Observations About the F75
- Thread starter RLOH
- Start date
RL just remeber this. The 75 at stock settings is hotter that most machines at full blast. The machine will amaze you every time you go out. The cobination of everything you said is what makes it shine. The speed and seperation is what throws most people off because of always useing a slower detector.
I've experienced about the same as you, RL, between disc. 5 and 6. There might be a slight loss of depth, but being able to hear the various tones among all the additional chatter when running 5 out ways the depth loss, if in fact, there is any. I dug a clad quarter this morning that was slightly on edge at a true 9" in pretty dry dirt. Checked the hole and got another slight high tone tic. Dug a little deeper, about an inch, and recovered another clad quarter. At those depths with the 11" coil the quarters were id'ing 75-77 and 81 out of the ground. That is pretty good depth in dry ground, IMHO. HH jim tn
