Audio Signatures And Sounds

Recommended Posts

I mentioned this last year and will re address the subject.  Has anyone compiled information of real signature so as one can listen ti clipping and signatures that a re funky in the different tone modes.  Although I have been a detectorist for years, many of the new detectors sounds tell more of a story than some are used to.  I am wondering if anyone has such a compilation.   It seems many love to post their finds on you tube but forget that the sound is just as important.  But they keep the headsets on which does not help the cause.. We are used in most cases to what some coins and jewelty sound like, but a clipped ring id different.  Perhaps some one might know of such a tool.    As always thanks for helping.

IMO - This one really comes down to personal experience, recovering targets and reinforcing in your brain's muscle memory what the detector was telling you.  I can't imagine just learning this by seeing pics of finds next to some sound signature or audio file.  Clive Clynick does a good job of trying to provide some general sketches of tone forms for various target types in his Equinox guides, but it is basically generalized.  The variability in environmental factors makes approaches to learning tones of limited value.

Hi Guy's

       I see where your coming at Chase I would agree with that, and there are some good clips out there (Gigmaster and others). However due to the videos, the trash hits are left out. One of the things that I have discovered is totally deteriorated metal buried in the sand that throws me for a loop.  I have just ( in the last year) been trying to learn beach hunting.  Spent many years in the pasture or parks. That is why we rely on you seasoned vets. Just seems though I am missing something and waiting for the magic moment.

I remember when the Sovereign was the hot ticket to have, there was an audio CD for sale one could purchase to familiarize yourself with the audio sounds of various trash and good targets.  All that is pretty well conveyed on various YouTube videos.  On most of my Equinox YouTube videos I share what the audio sounds like on targets as well as the TID. 

Problem is, and possibly why some don't take the time to do it is because it does take time.  If I'm hunting a remote site, my time's limited, but if I start making interesting finds, I'll generally start recording them, depending on my time crunch, I may or may not have the time to turn off my wireless headphones, rescan the target to show the TID and let viewers listen to the audio.  Then you have to repair your wireless headphones and continue detecting.   It doesn't sound like much, but if I'm at a good old site, with limited time, every time I do this, equates to less targets I'm going to dig at the end of the day and that next target may just be THE ONE haha

I try and describe best I can.  I have done some videos.  Problem is wind can cause audio in video to be lacking.  And a go pro may not capture all of the nuance since external speaker is used on detector to capture audio.  

I call these findings I talk about (say Eqx) as tendencies.  No absolutes though.  It pays to be curious especially with EQX !!

I guess , after reading  part or Clyde’s book and what Chase said make sense,@ I need to be more astute at looking at sizes, and if the location is more suitable for good targets as opposed to a locacation that is loaded with shell casings.  I did get Andy’s book yesterday and am tempted to dig into that.  I can only read so much of Clyde’s book before my head  spins and eyeballs come out.  The larger font in Andy’s book looks to be more amenable to adding eyeballs.  Anyhow still learning and I will recheck your vids Tnsharpshooter.

So you're saying there's no shortcut?  I guess that's one of the things that makes metal detecting fun -- the challenges.  There are so many variables when detecting.  We (hope I can speak for others...) tend to view the world in as few dimensions as possible, and that means too few.  Dave Johnson makes a sobering point in this monograph:

http://www.fisherlab.com/hobby/davejohnson/SearchcoilfieldshapeApril2012.pdf

There he states:  to say what happens when you swing a target past the searchcoil of a simple motion discriminator requires computation of at least 26 variables.

I emphasized 'at least' because up to that point Dave has only assumed a single target.  Add just one nearby target (with its own 26 variables) and....  I think I get the picture, and it's not a simple one.

For a long time I didn't even understand what you guys are talking about.  I hear a tone, what else is there?  Eventually I wondered if those of us who never experienced the analog detector era missed out, since not only were the signals rich, but you had to rely a lot more on what you heard, not what you saw.

In every endeavor worth pursuing, there is a threshold to cross which takes a person from an intermediate performer to an expert.  In metal detecting, this may be the one.  I know I'm not there yet.

That is so true.  Being from the older Garrett and Explorer crowds you are on point with decent tones.  Ironically this gets you thinking about target shapes as well as trash shapes.  For myself another learning phase.  What did they say " It used to be easy"  I'm used to new beginnings.  I read and saved Daves article, it does open the eyes.  Quick question, have you acquired the 6" coil?  and how would that fair at beach?

I'm sure someone else can answer the 2nd part since I'm not a beach hunter.  I have both the 6" and 12"x15" coils but except for tiny nugget hunting with the 6" in the Nevada desert I haven't used either one much.  The larger coil's extra weight bothers my back.  I can see using that in a survey, for example when searching a large plot for an old, long ago raized dwelling.

I think the 6" coil has the usual advantages (less ground and less trash in the field of view, increased sensitivity to tiny targets). However the stock 11" is so good at allowing me to distinguish good targets among moderate trash that its extra coverage leads me to use it most of the time.  But thanks for reminding me -- I need to put some more time in on the two accessory coils.

      Since I am new here, I wanted my first post(other that the meet and greet post) to hopefully be a contribution and perhaps help a few folks.
      One of the most annoying things when using a corded set of headphones is catching the cord on brush and whatever else it might be attracted to. Well, I recently discovered there was such a thing as wireless headphones but could not find any that I thought I would be satisfied with, so with some research, this is what I came up with.
      I bought a Taotronics blue tooth transmitter $29.95, a set of Cowen noise canceling low latency blue tooth headphones $59.99 and a Moborest 1/4" male to 1/8" female stereo adapter $9.98(2 to a pkg). Plugged adapter into my MXT, plugged transmitter into adapter, turned everything on including MXT, followed simple directions for pairing trans. to headphones and low and behold I now have wireless headphones for my detector.
      I put a small square of sticky back velcro on the transmitter(which is very small) and the another on the side of the machine and just stuck them together, to hold the trans. in place. The trans. can always be unplugged and remover if warranted.
      I found everything on Amazon.
      This may be old knowledge to some but I maybe there are a few folks this info. will help.
      Anyway, glad to be here and hope this will help someone.

      Plug in a booster/headphones into the WM12 (Gpz7000) or plug it directly into the 7000??
      Obviously, wire-free would be more convenient but would the signal be clearer/stronger going hardwired?
      (I'm not concerned about the minute bit of lag when using a wireless system)
      Thought i would ask before testing this on my next trip.

      Hopefully someone can help me. I have an Equinox 600 that I can pair my earbuds to but I hear no sound. The earbuds are paired as Bluetooth + as indicated on the machine. I have tried other earbuds with the same problem. I have reset the machine multiple times. I am using Soundpeats Q12HD earbuds. I am at a loss. Thanks

      Does anyone know what the waterproof plug Nokta uses for the headphones is, I have a pair of Tony Eisenhower headphones for my Nox 600 and want to convert them to Nokta, they are much more comfortable than the Nokta waterproof’s, Thanks

      Hi all, and thanks for letting me join. 
      I know this has been asked previously but I was recommended (by another forum user) to get a pair of AptxLL Qualcomm headphones to use with my 600. The ones I went for were August EP640 4.1, which is the same ones the user said works perfectly for.
      Ok, charged them up, switched on 600, switched on headphones to search for BT. No joy, tired it every way but alas, no luck. Two strange things, I can connect a pair of crappy standard headphones in a few seconds to the 600 but the lag and sound is so crappy it's a non-runner. I can also connect my EP640s to my phone , laptop and tablet in seconds. But not my 600. I sent him a message to ask what his experience with them was, he replied that he couldn't understand as his connected easily.   Help!
      Has anyone any answers/tips/reasons?
      Many thanks in advance. (Paddyspurs)

      The microphone on my grandsons head set stopped working so his mother bought him a new set.  I got the hand me down to use for listening to music. But thought I'd try something this morning.  Combining with my WM 08 I found the most perfect combination to date.  Great sound quality, blocks out the outside noise and feels great.  The best combination to date.  Very light weight and the head strap is angled to reduce fatigue on the ears.  And no 1/4 to 1/8" adapter needed.  Zero lag time of course.
