[walkerwm]

Hi Walker

All that chatter is because the F75 is fast enough to give an audio report on EVERYTHING it sees. I found a small pendant the other day that was litteraly less than 1/4 the size of a dime. It was in the sand of a volleyball court and I like to have never found it. It sounded just like what I would call chatter, but was repeatable.

I think if you take time to dig up a few of those signals you will find that the F75 is just reporting what it sees. So that is my take on why it chatters.

Now, as to what to do about it. If I'm not looking for jewelry, I set discrimination at 20 and adjust sensitivity down to settle out the unit. If you are running JE mode, you may go as low as 40, but will still get good depth. I found the small pendant using DE mode so even without the JE mode it will still find small jewelry items.

If you are looking for jewelry you will probably just have to put up with some chatter. Slow down and pick out the repeatable sounds. On most jewelry that I have found, it also has a small "footprint". If the signal is spread out over a wide area then it usually is junk, not coins or jewelry.

I hope that helps and good luck with your F75, as mine really performs well for me after I got used to it. I think you will love it after you get used to it too.

What he said. Keep out of the jewelry mode and keep the discrimination very low. Some sites seem to have a lot of background radiation or something that just makes the detector go haywire. I have also found All Metal to be at times quieter than discrimination mode!

Toying around in all the modes I find plowed field is the most stable, followed closely by default. Certainly because they "dumb down" the detector compared to the hyper jewelry mode. You certainly don't need to be in the jewelry mode to find jewelry. Just consider it a bouns when conditions allow you to use it. That, or develop an ear and eye for when to dig and when to ignore the "sparky" background chatter in that mode.

I can typically run sensitivity to 90 in default but only 45 or so in jewelry. Some locations I can get jewelry up higher, others it never calms down.

I also notice that holding the coil to the grund or sweeping it is much quieter than holding it up in the air. Do your adjustments with the coil down after the "F" disappears from initialization. And forget about turning the unit on indoors.

As has been stated, most of the chatter is the detector telling you what is in the ground. The f75 is one of the most sensitive, if not the most sensitive, machine out there today as well as extreemly fast in processing what it is telling you is in the ground. I mainly hunt for coins and jewelry and the settings I have pretty much settled in on are disc. 6-10, sen. 75-80, tones 3h and process de. In trashy areas, which seems to be where some good stuff still remains, I listen for those mid and high tones and if the site has enough age for IH and other older coins, I dig most mid tones. 3 of my IH's have been mid tones with readings 55-60. In the 3h tones, both of my gold rings were a high tone, but different readings. The 10k white gold read nickel, 29-30. The other 10k read 53-55, but was a larger ring. One other thing I am now noting is in very dry ground, such as we now have here in W. Tn. is readings are somewhat bouncy. Silver, though, dosen't seem to be quite as much. Hope this is of some help as the f75 is a good one. HH jim tn

I talked to him the other night in chat. He is running the disc really high.I told him to lower it to around 10-20.

Ah.

When purely clad coin shootin I have run disc to 55 and notched nickels back in from 25 to 35, but in default or bottlecap (with 3H or 4H tones) and even then I have to back sensitivity way down to 40 or 45.

But, oh, what a sweet machine in plucking out the coins among foil, pull-tabs and bottlecaps where the carnival sets up every summer.

Now I'm going back with low disc or in All Metal and hitting deeper dimes and nickels that I missed at that high disc setting. That park is on a flood plain and it's taken a lot of silt in floods the past two years. Found a 1980 quarter at 9" and many dimes from the mid 60's at 7" & 8". (No silver yet, dag nabbit).
