I know people exaggerate depths and some are conservative but I always use the carrot to determine and get pretty close. My deepest dime so far was a 44 wheat at carrot depth, 9". I know it will hit coins much deeper but I tend to run my 800 at recovery 7 and iron bias 1 90% of the time. The deeper coins just give a whisper but they're undeniable when you get over one.

Hello HighVDI,

I must be doing something wrong because I cannot get much depth from my Equinox 800. Soil is good, but the deepest coin I've found has been a 7" wheat cent from a pounded park. Everything else has been 4-5" range modern clad and copper memorials. I've been running Park 1 or 2 with 20-22 sensitivity and tried recovery speeds of 1 through 6 without any difference in performance. I've notched out everything below 11 and 15 through 19. Ground balance default of 0. Iron bias 6.

You mentioned the low volume signals. This has me thinking I may not have the volume set correctly because I'm hearing all target signals at the same volume.

Thoughts?
Thanks - Mike

I went back old premission that pounded with my etrac found just two silver coins and tons of wheats, so went back with my equinox, factory setting park 1 and faint high tone and out comes out a 1909 barber half a bucket lister and 9in next target was a 12 , V nickle st 8 to 9 ins. My deeper coin was 10 ins a 58 Jefferson. So to to me the equinox 800 goes deep , the only person I've got prove to is myself.

Congrats on that Barber half Jimzz!

The depths and recoveries you and others have been reporting with the Nox blow my mind. I have not found anything in the areas I have already gone over with my Explorer II. Based on what I have been reading I should be recovering some deep silver, nickels, etc. that I missed but that has not been the case and I am about 30 hours with this so far.

Only have 18 hours one mine so far, but it slams an 8 inch silver half dime in my Coin garden, And a slams a 9 inch dime as well. So if you hunt carefully I'm confident it will hit a 10-12 inch dime. Ill have to bury another at 12 and see what I come up with. I already have like 100 bucks worth of coins buried haha guess it can't hurt to bury a few more. Just hurts driving em back in the ground after saving them.

I have had and became at least proficient with four decent detectors. It has been rare for me to find coins below 7" in this mineralized, hard clay and rocky soil in western AR.

In Michigan we have nice black top soil in the areas I hunt. Likewise, 7 inches seems to be the max for coins. Anything deeper has been larger pieces of brass or iron. I will say that when I measure I use the scale on my White's TRX. I do not include the grass in the measurement so maybe others are factoring in a couple inches for turf?

The reports of 10-12 inch deep silver dimes with the Nox are hard for me to believe given the poor depth I've experienced so far. Hopefully, I am just not setting it up properly for max depth and will eventually learn.

Perhaps you haven't went over a deep coin that you noticed yet?

Lately while silver hunting I've been lowering the t1-t3 volume way down and maxing the t4-t5 regions.

Maybe try iron bias around 2-3. I found deep silver in both park 1 and 2 so I know it's capable in both. I've dug deep targets in recovery 7 also. The only thing you need to watch is the faster the recovery, the more shortened the signal length becomes and they get easy to miss. I like the higher recovery because IMO the signals give way more clues. I've had peeps for signals coming in thay were high toning and had a nice faint tone with NO vdi at all or in a region that should have been low toning. I think this machine is more swayed to the audio from my experiences so far.

Maybe try to bury a few silver and other coins and keep going deeper to the limits of the machine. If you can't hit a 9-10" dime in recovery 6, sens 19 and up then IMO something could be wrong. I like searching with sens. a little on the lower side rather than on the ragged edge of falsing. Just seems to pick out the deep silver better.

I meant 9" 44 merc in my original post too....not wheat. Wheat pennies are a whole other story. This thing is a wheat penny destroyer! Lol.

I dug a penny at around 4 feet once! Ok...it was closer to four and a half feet but i am sure nobody would ever believe that!

I've still got my 800 in the box . Been using my 600 but going to put the 800 on charge for the weekend. Looking forward to playing with the extras.

I appreciate the tips and will try these adjustments. I have been using 22 sens. Had it out again last night and listened for the high tones to break through on 6 recovery speed. I could hear them but few were repeatable.

I can confirm the equinox goes deep on coins and very deep on large copper and brass objects. I dug a copper faucet 18 inches and was hitting hard with the coil an inch above the ground. Saturday I dug deep wheats and a barber dime. These were all 8 to 9 inches. I was in park 1, 21 sensitivity. The signals weren't the best but I was getting a high tone and partial vdi at all angles. I imagine quarters and large coppers would ring in well at 9" +

Keep in mind , Notching is just another filter.....every filter you add to a custom program will effect depth. Instead of notching try just lowering volume and or tone on certain areas you are currently notching. See if that makes a difference on your depth.

I can read manuals, but a lot of the stuff does not sink in until much later. When you change brands like the Garrett AT Pro to the Nox 800 a whole lot of differences. For the first two weeks my brain was stuck in the AT Pro mode.
Now a month later, it is getting more into the Nox 800, but still not there 100%.

If you are a previous minelab user, I think you have a huge advantage learning the Nox. Even a newbie might have an advantage of us coming from other Brands to the Nox.

things got better for me when I set up tone breaks to make the coins stand out and all other stuff at a lower pitchs and volumes. You can still hear all the junk in the background but when you hit the good stuff you know it.

I'd like to try this but am a complete noob as far as setting up tone breaks. I've been using 50 tones.

If the iron bias is zero it lets all iron audio through, if you raise the iron bias the amount of audio response from iron is reduced. I raised mine to 2 or 3 to eliminate nails from sounding off as good targets.
I thought on this Iron Bias thing for a bit. In fact thought a lot about all the other possible setting that can be increase and or decreased. Coming from the Etrac my theory has always been use as little discrimination as possible to maintain depth. Instead of increasing Iron bias which would induce discrimination and affect depth.... I've been trying to set it at zero and limit the volume and tone of non target areas. One would think this would mean less discrimination should help keep me detecting deep. Another thing I've noticed is a lower recover speed will allow deeper coins to sound better, especially when you get those high short tones that don't always repeat. I've dug a couple 10" wheats that only sounded good one way w good numbers.

If you are using a preset program (like Field 2) that has 50 tones set as the default, you need to change it to 5 tones first to set up these custom breakpoints.
