Ok, complete noob question here: When Im out there and listening for tones on my Equinox 800, why dont some sounds register a number? I hear all these little sounds and noises but when I go back over they sometimes disappear. Sometimes the noise changes or is very hard to find again. What can I do to help myself isolate these sounds and is every errant sound something to dig?

Hey Sid,

First I'll point you to a similar question I asked several weeks ago, and got some great answers that really helped my progress with the Equinox 800.  It's this thread:

I struggled with this at first too.  The Equinox is a very "hot" detector. Hot meaning it's extremely sensitive, to both targets and ground conditions.  So first off make sure you perform the recommended noise cancellation and ground balancing procedures. Secondly I found it very helpful to turn the sensitivity down from the default of 20.  I was running it in the 14 to 16 range, sometimes going to 18 for the first few weeks with good results.  I'm a new detectorist and I'm sure some more experienced folks will chime in here.  But suffice to say the Nox can be a bit overwhelming at first, but totally worth the time it takes to learn.  I highly recommend getting Andy Sabisch's Equinox book.  It was a great help to me.

I have limited experience, but I hope this helps a bit.

Great reply to Sid, Bash.  

Sid - a number of factors can result in an audio blip without numbers showing up including EMI, ground noise and anomalies (a patch of mineralized dirt), and micro targets or deep targets.  Regarding the latter, if you can't readily get a repeatable audio signal then just move on.  At this point, in learning your machine, just focus on digging the repeatable no brainer signals (trash and treasure) so you can train your brain on what good and trash targets sound like.   Read Bash's links regarding how to combat the noise sources (in short, do a noise cancel, reduce sensitivity from the default 20 setting  (these help with the "sparkiness" caused by electromagnetic noise sources - EMI), and if you find you are having to reduce sensitivity a lot (5 points or more) then consider changing modes or switch to a single frequency to see if you can make the noise go away, and properly ground balance to make ground noise that shows up as -8/-9 numbers go away).  If you are still having issues, then repost with specific information such as mode you are using and sensitivity setting, whether there are power lines or a lot buildings nearby that may have wifi or other sources of electronic noise.  Also, put your phone in airplane mode or place it in a pocket opposite from the detector's control panel (i.e., on the side your body opposite from where you swing the detector).  Good luck.

That sounds like falsing on iron. Turning sensitivity down does help.  Turning up iron mask works but you loose separation.

So turn down sensitivity and if you have to, turn iron mask up a little. Also try blocking -9 thru -7 or higher which might help on ground noise. I haven't tried this yet so I don't know if it helps.

In addition to the great advice above, I can only add that the NOX will receive and sound on lighting strikes. In fact, when it gets really chatty for no other apparent reason (mentioned above) it is time to leave as a storm is nearby. It hears the approaching strikes before you hear the thunder. YMMV or as Colonel Dan says "the view from my foxhole".

Cheers

What Chase said.  Lay out some coins and other targets on the ground and get those clean hit sounds of good targets in your brain.  For the time being concentrate on digging just those target responses. 

Something that is seldom brought up and I feel is important especially to someone new to metal detecting is headphone volume.  Ears being highly sensitive organs  need protecting.  There is a right and wrong way to set the volume and this is based on how our ears react to changes in volume level.  Changing from a loud to a softer level tricks the brain into thinking you are good to go but actually results in setting a too high level.   Do the opposite, start low and slowly increase it until it is comfortable for long term use.

Tom that tip with the headphones really helps with a noisy detector. You don't notice the noise so much with the volume down but the targets come in clear.

Looks like SidTheKid isn't going to respond to any of the good advise offered above.

My first thoughts are that he is running with too high a "Sensitivity" setting resulting in falsing.

I suggest do a "Noise Cancel"  drop the "Sensitivity" a bit at a time and "Ground Balance" then another "Noise Cancel".

      Hi everyone, first post. I'm currently new to metal detecting and I am using a loaned Whites 6000b coinmaster. I haven't dug anything but junk so far but I'm considering buying my first detector. My coworker has a Minelab CTX 3030 and I don't imagine I'll buy something that expensive as a beginner. I was looking at the Minelab Vanquish 540 or the Garrett Ace 400. I know very little about the different detectors but not looking to spend over $500 on my first. Any help would be greatly appreciated.

      I just recently got one of these Russian boards, which IMO looks like a good piece to work with. I read over the supplied build instructions which are fairly clear, but in a way are not totally, at the same time. I have worked with circuits quite a lot over several years, I went back to a site that discusses working with timer IC's of which in this build uses the 7555, a CMOS version of the vaunted 555 that uses 1/10th the power. This is where the MD transmitter freq. is produced. There are several ways to construct the oscillator and in the case of this design, I find one very small issue. Since as I mentioned, I just got this board and still working at putting it together, obviously I haven't tested it. Here is what I am here to discuss with anyone looking at this version, thinking about building one, or has one working. The 555 system has been know to experience unstable responses if there is no Capacitor connected from pin 5 to ground ! There is no Cap to pin 5 included in this circuit design and it uses a few other features that differ from the basic osc. circuits  A .01ufd cap which on this board can be installed on the back side of the board from pin 5 to the nearest ground buss and should be some improvement to the function and stability of the circuit, it is 'optional' and it will work without it. It is a very small mod but in my experience sometimes that is all it take to work or not. I also suggest to use .100 inch header pins for connecting any of the peripheral parts. Doing this makes it easier to R&R the board for working on it, you will need to be extra diligent about connecting everything back in the proper place but if you have gone this far with this project, that is a no brainer. There are a couple of places the .100 header pins will not fit perfectly but you can get around that with the use of a single break away pin and just a tiny bit of force to re align so your connection will fit as you continue assembly. 3 pins on the right of the rough GB Pot on board are one place, another is the 2 holes just to the right and above the 4 large elect. caps around the Vreg, LM7808 or LM7809, also using a 7809 might give you a slight bit of bump in performance. Since the circuit uses a +12v supply battery, there is still a bit of margin left so that the dropout V is going to remain above the output V of the regulator until batteries are getting too low. Using a battery carrier that holds 8 AA cells, alk or even NiM rechargeables will or should work and you should still be able to get this inside the housing. The use of NiM may exhibit an issue with the 7809 so make the choice based on what battery V you plan on using. One could also use an extra bat pack in series to push the V higher for the input, as the 78xx can handle up to 30v input, this will give you a lot more operation time before the dropout V becomes an issue. I would also think installing some reverse polarity protection here, 'NEVER a bad addition to any circuit and simple, a couple of small diodes and a fuse added to the project, around a 200 milliamp mini fuse is a good rating, put some extras inside the case. The current draw of this unit is very low so you can run your batteries way down this way and still keep going, having a small solar setup would be a good thing to have with you to boost batteries also, you could make it to fit over your hat!!! I am in the U.S. and have considered doing assembly of projects in the future,,, if my board works out. The one good thing I like about this system is that it should work with several different coils out there and one can even construct their own coil if using careful attention. Coils are really not that hard to make if you have and follow the instructions. Making the casing is probably the worst part of it, using resins and hardeners. Shielding is a bit critical here. I will mention that it is almost essential that you have an oscilliscope to build one of these for adjusting the timer section freq. the 5k pot on the left side of the 7555 and also setting amplitude on the upper right of 7555, the one just left of the 14 pin IC spot.. If you don't have a scope, there are apps online that make your PC work as one and you will have to learn how to use it, or get someone that knows to help with it. Also a transistor tester is helpful and when working with these parts, you MUST know the pins and install them RIGHT if you intend to have it work but you already know this if you are thinking about assembling one.

      I would like to start detecting neighbors property, but I am not sure how to go about it. Does anyone have advice on asking my neighbors(who I don’t know very well) or asking people in different neighborhoods? How do I tell them there yard will not be damaged. I dig my holes in a circle in my grass and pull up the plug. I then check to see if the signal in in the hole or in the plug. Wherever it is I use a t shirt to put the dirt on and find the target. I them spill the dirt in the hole and place the plug back in the way it came out. It does look a bit brown after I do it, but as time goes by you can’t even tell. I did it in my yard lasted year, and this year you can’t even tell. Is this a good way of digging, or is there a better way? Any advice is appreciated!! Thanks!!

      Thinking ahead. Will be moving closer to Clearwater and St Pete Beach Florida later this year. What metal detector would you choose for wet sand and shallow wading - an Equinox or Impulse AQ (assuming its available)?. Based on what I have read, it seems Impulse is supposed to find gold rings that Equinox has missed.

      I am pretty new to detecting, having used friends detectors from time to time, and am looking to purchase my first detector.  I can get a pretty good deal on either of the two, and am wondering what experienced hobbyists opinions are on which you would buy between the Fisher F5 or Nokta Makro Simplex, and why? Ease of use isn't really a concern as I am confident I can learn to use either.
