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.

      This almost seems like a stupid question but I have to ask.
      Does anyone wear their Hearing Aids with Headphones?
      Thanks!

      In all the research I've done so far, the 2 waterproof headphones that get mentioned the most as the "best" options for underwater with the Equinox are the Patriot Headphones (http://metaldetecting.com/en/patriot-equinox-water-weq) and the Tony Eisenhower's Headphones. Has anyone actually used both and can accurately compare the 2 models? I'm talking in terms of volume underwater and comfort.

      Before the sun broke out in full force today I did a quick run about  1 1/2 hours to test out the Nokta waterproof headphones on my Multi Kruzer. Ran it at 19khz looking for small jewelry, found 2 1/2 earings, cruddier one might be gold brighter one is plated. This pond is brutal with iron as you can see the black chia pet looking thing on the side. It is a hard drive magnet I stick in my scoop to catch nails and bobby pins. You can see some of the rocks that also stick to it. My GB was low to mid 90's so ended up using Gen Mode in the quieter areas and 3 tone for the most part.
      Headphones are little better on audio than my Garrett waterproof ones, audio sounds similar, maybe bit less tinny but you do need to kick up the volume. I usually run the machine on 3 but use 10 on these. Vibrate mode proved to be useless because of all the iron in the ground there as it just constantly runs. Bottom line if you got a Kruzer or Amphibio, well worth the investment if you plan on splashing around.

      The headphone cable on the AQ underwater headphones is over 6 feet long. But it is coiled up so tightly it pulls on and stresses the cable near to where it connects to the detector.
      Now certainly a good preventative measure is to use a tie wrap to attach the cable to the rod under the elbow as a strain relief. I'm a little lazier though and want my headphones to not be pulling that hard in the first place. The cable should hang with a bit of a slack in it before it gets to the detector, instead of pulling sharply upward.
      So this is an oldtimers trick to relax the cable on new headphones. Just tie them up and let them hang. You usually do not have to worry about them getting too long. In fact, you may have to do it again later as the try to go back to the original coiled configuration. But I get mine to where I want them, and worry a lot less about stressing the connector down the road.

      I will be using my Impulse with the battery end well out of the water while shallow wading or on the beach, etc. I wanted to get away from wired phones and save the waterproof phones for when I actually need to submerge the machine. No sense putting any more wear and tear on the cable than I need to.
      So I found a source of relatively inexpensive M8 pigtails and cables, AutomationDirect. Never ordered from them before, but it was easy and cables arrived in two days. I got two pigtails for the headphone 5-pin connector, one straight, and one 90 degree. And I ordered a couple longer 4-pin cables for the power connection, to work with a high capacity power pack I have on order. More on that later when it arrives.
      I decided to use the 90 degree cable to make an adapter for my new TaoTronics transmitter/receiver box so I can use my Minelab phones, which I like, with all my detectors. There is also a less expensive transmitter only version.
      M8 5 pin 90 degree pigtail

      I dug through my pile of adapters and found a spare mono 1/8" extension cable and cut it off, saving the female end for this project. The TaoTronics comes with a RCA to 1/8” female cable that would also probably work for this. I hooked up the 90 degree cable and powered up the Impulse. I randomly hooked up the two wires from the 1/8" socket to the five while having some stereo earbuds plugged in, and found that the brown and gray wires gave me audio in both ears. According to the chart below brown is #1 and gray is #5. I wanted to make very sure there was audio in both ears using the mono socket but with stereo phones plugged in, so good to go there.
      I cut the cable down short, spliced and covered with shrink tube, and wrapped a little electrical tape on to add some beef. Not pretty but it will work - a typical Herschbach job. I bent the cable under the armrest, and added a stick on square of Velcro to back of the TaoTronics transmitter and the leg stand. I'll add more squares to my other detectors so I can move this transmitter around to whatever I am using. A little tie wrap secures things.
      Fired it up, paired easily with my Equinox 800 headphones, better audio than the Fisher phones, and frankly the Equinox phones are not the best in that regard. Cheap, super easy... I'm quite pleased with this. I can of course use 1/8" type wired phones or ear buds if I want. I'll make another adapter with the straight connector but go to 1/4" with it, so I can use my Sun Ray Pro Gold headphones without an extra adapter. I'll probably make that cable a little longer than this one, which I wanted as short as possible.
      If you got the TaoTronics transmitter only box for $20 and this cable for $8.50... well, this is pretty cheap and easy, and will work with a huge number of headphone options.
      Ironically my new Tarsacci MDT 8000 comes with am M8 to 1/8" adapter with one little problem. Fisher uses a 4-pin connector for the power/headphone combo cable, but then for some reason they use a 5-pin M8 for the headphone only connector. The MDT 8000 headphone adapter is of course 4-pin. I swear they must all have secret meetings to make sure nothing from one detector ever works with another.

      Hey guys,
      I've been using my Nox 800 underwater (salt water) for some days now (7 underwater hunts total, about 2 hours each), and thought I could share some first results, plus give a nice and cheap alternative to the minelab yellow headphones for underwater use if anyone interested.
      My first ever snorkel-dive with Nox in my usual pebble beach was by using just the speaker (no headphones) with my head submerged, and as expected, I soon realized that this wasn't enough...even with my head underwater was very difficult to hear through the speaker due to extremely low volume even in calm sea...(however, as already posted in my first topic in the forum, I was still able to get my first whote gold ring with Nox using just the speaker 🙂). Anyway, in my second hunt I bought the Minelab's yellows, but to my experience with them, again I wasn't able to hear the signals good enough underwater due to their low vol especially after some minutes underwater when the soft earpads and the space between was geting full of water. Furthermore, the yellows are huge headphones and I need to be more descret in my beaches this time of year. In my last hunts however, I tried something different and wanted to share my experience...I bought a pair of 100% waterproof and submersible swimming in-ear headphones especially designed for swimming and watersports that had some quite good reviews from athletes around... the product is the "H2O Surge+ waterpoof headphones" (company is "H2O") and bought them for $40 through Amazon...(arrived from amazon UK). Well guys, in my last underwater hunts with them, my experience is tremendously good....their sound quality underwater and their volume is honestly out of this world, and I'm not kidding...especially when comparing to Minelab's yellows. Volume is high enough to hear even the tinniest faint signal and you feel the tone inside your ear like hell... their earplugs completelly seal the external sounds also, and their sound-tones & bass quality is very immpresive for such a small pair of headphones. These small earbuds come with a 3.6ft straight cord so at least for me were comfortable enough while snorkelling and still able to leave the Nox in the bottom (chest depth max) while relaxing in the surface with my mask waiting for the "recovery fog" to leave. Their speakers are 100% waterpoof (IPX8 rating) and can be submerged to 3.5m depth no prob. The company states that maybe sometimes they need equalization (blowing air inside them) but sinnce now I didn't need it. However the cord is thin so you mast be carefull not to stretch it, and if you feel to you can make an easy mod to seal the hole-plug of the Nox where they are inserted (I made a simple yet effective mod by drilling a small hall to the original plastic protective threaded plug of the nox, and used 2 perfect fit o-rings inside to seal the 3.5mm jack connection while screwing the plastic plug...you already know that the nox is waterproof in that point also, but better safe than sorry and made the extra mile to seal it better). As already stated, the H2O earbuds are designed for athletes (especially designed for swimming and watersports) and come 5 sets of earplugs to fit perfectly in every ear...in my ears they fit so nice and they completely seal external sounds and water from my ear canal. Don't wanna say much more about them, and waiting to see how they handle overtime, but as for now I'm totally impressed with them and their volume and sound quality, and my finds went immediatelly up.
      Furthermore, In fear of flooding the Nox in the future as many other members experienced, and in order to make it more usable underwater while snorkelling, I made some extra mods. I totally water-sealed the machine by: a) using silicon paste inside the battery compartment inside the handle (removable if needed but should be a pain to remove)...b) used marine epoxy paste to seal the control box and screen perimeter where the plastic parts join together, and also sealed the point that the control pad meets the handle (critical point there).... c) completelly sealed and eliminated the external speaker (will never use it anyway)...d) made a custom shaft by modifying the original lower shaft to shorten it and also drilled a small drain hole near the bottom...I know I may void the warranty with my mods, but took the risk and now I'm using the machine underwater with piece of mind.
      Results: As already said, I have used my Nox underwater for 7 hunts till now...about 2 hours each. Attached some photos of the finds. In these +/- 14 hours I have:
      - 4 gold rings: All are solid gold (14k & 9k the smallest one), except the large and heavy one wich is bi-metal silver with 14k gold piece on top. (ps. the top white 14k gold ring with small diamonds is the one I posted some days ago)
      - 1 crusifix (silver with gold Christ) 
      - Almost €22 in change
      - 82(!) old clad coins (all are pre-euro drachmas..no worth unfortunatelly, but yeap 82 of them in these 14 hours)
      - Good amount of lead sinkers (including some huge ones)
      - 2 spoons, 3 keys, a jank pin jewel piece, a junk watch, and a live HXP-95 military cartridge (strange to find it underwater though..!)
      - Aluminum junk: MINIMUM!..we're talking almost no junk comparing to dry hunt!!! I think I gonna love this underwater thing!!!!! 😄
       
      Ps. My Nox settings if someone's interested are: Beach 2, Recovery @5, Iron Bias F2@0 , 2 tones only (pitch 1 for iron / pitch 23 for non-fe), notch only -9 to -7 to avoid ground/ceramic rocks underwater (all other is open and able to hear iron from -6 to 0 in low vol pitch 1), tone break @0, sensitivity @17, GB manual by pumping sideways (have uneven bottom), no threshold.
       
      That's all 🙂
      Happy hunting everyone!
      Argyris
