Forgot to mention I tried different single frequencies also. Spent about 4 hours trying different things at one of my worst colonial sites that produces new items every time the ground is turned over for planting. It is only about every 5 years now since everyone in the US practices "no till" planting. It seemed like 15khz was the most quiet and 5khz the most noisy. 20-40khz were very  similar to 15khz. Almost every plug will have 3-5 square nails. The ground is full of fertilizer. The first 5-6 inches is organic top soil and underneath that is solid red clay but with really low iron oxide content.

After doing lots of tests, I have concluded that this is just caused by different types of mineralization, and is just magnified by the Multi-IQ technology. Rocks, red clay deposits, fertilizer, etc. Areas where the Deus mineralization bar would barely register sometimes sounds like and iron patch with the Equinox in multi. If I change to single frequency, it is almost eliminated. The two main settings that really affect this are sensitivity and recovery speed as previously suggested. I usually run recovery around 5 unless I get into a lot of iron. If I raised it to 6 or 7, and then lowered the sensitivity to 15-18, the ground noise would almost disappear in multi. None of the other settings except for manual ground balance made any difference. I am going to play around with the tracking ground balance and see if that helps. Thanks to everyone for the help.

Not sure. That was the main reason for starting the thread. It has me scratching my head. I haven't had a chance to test the theory because of the weather, but someone mentioned fertilizer as a possible cause. I hunt a lot of rural areas. 

Usually run sensitivity between 20-23. My soil is pretty mild in most areas. Have gone down to 15-18 to try and get rid of the "ground noise". If I'm in heavily concentrated iron, I will run 12-15.

Might get to play in the mud next week. Supposed to be in the 50's Sunday!

They aren't repeatable signals, but usually show up around -9 to -3. Most square nails are around -3 to -6. Guess I could notch out to -3 and still hear the iron. Just got about 5 inches of snow, so it will be a few days before I can try beach mode. I've tried all the park and field modes, and run sensitivity as high as possible. Turning down the sensitivity doesn't help much either. Never thought to try beach mode. That might make a difference if it is mineral/salt related. Hunt a lot of rural areas with crop fields and pastures. Could just be a lot of fertilizer in the ground. I run into a little red clay every now and then, but it is usually pretty quiet.

It is strange. My Vanquish doesn't do this on the same ground. Equinox must be more sensitive to the ground minerals. Guess I can look for the iron patches in single freq and then switch to multi.

Interesting, usually it is the other way around?  

My thoughts too. Thought multi would be more stable. It even seems to separate better in iron that single frequencies. Has me scratching my head. Have had detector for three years, coil replaced for broken ears, and has always done this thinking back with both coils. 

Yeah I've never really ran single frequency much until recently and thought the same thing when hearing iron tones. Running 3.0 ATM.

I'm pretty sure it's not EMI. Remote sites act the same way as urban areas. Deus doesn't pick up any EMI at the same sites. It only happens while the coil is moving on the ground in multi. I almost always have nothing discriminated unless I'm cherry picking a park. I'm usually hearing -9 to 40. 

Been detecting for years, but relatively new to the multi frequency game. I am experiencing a lot of ground noise in multi that isn't present in single frequency. I was amazed at how much quieter single was compared to multi. When I use multi, it sounds like there is constant iron (low iron tones) with every swing. This happens every time and not just particular sites, and in different modes. I can't distinguish nails from what I'm guessing is ground minerals? In single frequencies, it is super quiet, and I can hear every little piece of iron. Once I noticed the difference I started digging low tones just to check. 90% of the low tones in multi aren't actually targets. I alway noise cancel and ground balance. Live in south central KY with pretty mild ground. Is this just a side effect of multi, or am I missing something?

If you open too many bottles, you might hurt yourself.😂

CD is a coil disconnect error.

EDIT: Just noticed the water intrusion. Nevermind...

They claim it can go 30 hours on a charge. I get about 10-12 with the Minelab rechargables.

An extra tone option similar to pitch or full tones like the Deus. It would be awesome in heavy iron. That is the one and only reason I was holding on to my Deus.

That's the same design I was looking at. Seems like it would help transfer a lot of the pressure back to the coil. Found out my local library has a 3d printer but they only use pla. It won't be as strong as abs. It's only 6 cents per gram so I am going to have them print one to try out. I can get one made from abs later if I decide to use it.

Mine hadn't broke off completely yet. There was a crack all the way through at the 2 o'clock position. I was always worried about them breaking and recently cut out some milk jug plastic to go behind the rubber washers. Maybe it was my fault one of them cracked.

Just got bitten by the broken coil ear bug. Have had the Nox for 2 years and thought I was special because mine hadn't broken yet. It is on it's way to PA. Wanted to get one of the stiffener devices to put on the new coil for insurance. I've read a couple of horror stories of both ears breaking off after using one. I was leary of just buying from eaby or amazon. If you use one who did you buy it from and how has it worked?

+1 on the Aukey B80's. I got lucky and caught the light gray on sell for $30 last month. I use them with the Equinox and Vanquish. Tend to get about 6-7 hours of straight use with the volume turned up all the way.

Pretty much the same for me. Mainly use Deus Fast and Deep. I have a heavy iron program that is based off Deus Fast with negative disc and full tones. It is my clean up machine for iron infested sites though. The Equinox has just enough features and is my first in. I don't like cherry picking with the Deus.

Each frequency gives a slightly different VDI on the same target. ID norm makes the Deus give a consistent VDI on a target across the different frequencies. It shouldn't matter that much since the Deus is a tonal machine. The Deus VDI isn't very accurate past about 6 inches. It will still try to up average deep targets in to the 90's.

Wifi signals can also cause it to go crazy. Just about every house has a wireless network. You can try holding the coil in the air and noise cancel a few times to see if that helps in trouble spots. Can't remember how many frequency offsets the noise cancel has off the top of my head.

Sounds like some kind of EMI interference.

Might be a silly question, but I can't find the answer. Seems like all the lower end detectors are always around 5-8 khz. I was always under the impression that the sweet spot for the biggest target range was around 12-18 khz. Are the lower frequencies cheaper to implement, or is there another reason? 

Lesche was a family business. George had a falling out with the family members he was in business with and started Predator Tools. The new Lesche company doesn't have the same quality that the George Lesche tools of old had. That's why you see Amazon reviews of the newer Lesche Sampson shovels bending/breaking. Some people don't know there was a split and still recommend the Lesche name because they are still using George's tools from years ago.
