Taking advantage of the fact that I have several Equinox series coils, I decided to buy an X-TERRA Pro, and make an all-terrain detector that, due to its cost, I did not mind leaving always in the back of the car. So I attached it to the Nox 10x5 coil. Fantastic, I am a fan of hunting with small coil and maximum separation, especially in the water. A few years ago, my headphones in the Equinox 800 broke down on an underwater detecting trip, and it was agony not being able to hear underwater. Now I was wondering how to "free myself" from using headphones underwater. The Xterra has the vibration function, which is a plus, but for me the audio is the most important thing. So, thinking about the matter, I made a parallelism between the sound propagation in the water of, for example, pinpointers, which can be heard ok, and how to achieve these properties with the Xterra. Thus, Iñi decided to cover the speaker with a very firm film, and seal the edges with hot silicone, so that the speaker could generate the sound in dry, and that this sound, when colliding with the film, could be transmitted underwater. If the speaker gets wet, even if it doesn't get damaged, it doesn't generate sound properly. And today I did an immersion test. Sometimes I detect in the water up to the snorkel, and as the ears are always underwater, I can hear the sound reasonably well, and combined with the vibration function, means that I can use the Xterra/Manticore/Equinox underwater without the headphones. I hope this mod can help someone who owns Manticore, Equinox or X-Terra Pro models and wants to use it differently 👌

I am interested in changing out the headphones on my Excal. My intended use is diving down to a max of 30 ft. Would you all recommend a hardwired connection or a CTX-style connector? I can see advantages to both. With the CTX connector I can try different types of phones for underwater, but the hardwired connection may be less likely to leak. Any advice? Thank you!

Hi Everyone: I have posted this on another competing forum. I thought I would post it here as well as this forum seems more active. Part of my issue is the poor volume with wired headphone issue I have seen mentioned multiple times but I can live with that and my issues go beyond that.I have had the Simplex for a little over a month. I have the Nokta Makro wired waterproof headphones and while they worked OK for a while (volume had to be on the highest setting to be of much use in the water) they recently quit working altogether. If I am in a silent room I can just barely and I mean barely hear a peep out of them if I run a coin over the coil at the highest volume setting and I have very good hearing. I just ordered a pair of the Gray Ghosts for the Simplex and I received them tonight and plugged them in and I'm only getting audio out of one side and they too are not all that loud at the highest volume setting. I plugged a pair of basic Sony wired headphones into the machine using a 1/4" adaptor and the included headphone adaptor cable and they worked great with very loud audio so it isn't all headphones. Also, the machine charges and updates perfectly fine so I wouldn't think something was wrong with the port on the machine. Could I have just gotten two dud pair of headphones? Has anyone used the Nokta waterproof headphones for this machine or the Gray Ghosts and have had similar problems? Thanks

I bought these to wire with another machine. Has anyone spliced these? It has an extra black wire which I assume is just from a general audio wire they used which is probably microphone, so it would have no use. (unless im wrong) Anyways, when I wire these into a 3.5mm jack they are really not loud at all. Any advice for getting them really loud? Thanks

I logged into Minelab's "Detector Center" to file out a ticket on the ML-105 headphones today. I used them yesterday, charged them yesterday evening and they were dead as a doornail this morning when I got to the beach. I was lucky enough to have the headphone cable in my car, so my hunt was not totally spoiled as the headphones worked with the cable. When I got back from the beach, I tried to charge them. I even tried with three different USB cables and with different USB to 120V outlets. The results were the same as there was never a red led light to show that they were charging. It appears that the battery is dead. That's when I logged in and started a ticket at the Detector Center. So, we will see how Minelab handles the ML-105 problems. Joe PS I have been using the Manticore since the middle of Jan.

Seems an odd move supporting the completion, but I suppose they see it more as making money off the competition. https://www.questmetaldetectors.com/product-page/aptx-low-latency-bluetooth-wireless-headphones-for-minelab-equinox aptX Low Latency Bluetooth Wireless Headphones for Minelab Equinox The customized, professional grade high sensitive speaker drivers deliver all the details of the signal from the detector.

I’m 61 and don’t hear as well as I once did. Do a lot of relic hunting in wooded areas. What is your favorite headphones for sound quality?

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. Su Amigo, Canoe

I couldn’t wait to get out after seeing Calmark & Gerry’s Flood Pictures of Rye Patch dry washes! Though I’d give it a few days to dry out and for a Road Crew to fix the main dirt roads. Road Crew, did a great job with a new Culvert installed on the main drainage of Poker Brown wash and regraded it to my left turn to the Majuba Placer. I was impressed with the erosion of this storm, had to be one for the record book. Being a student of Hydrology during my dredging years, I learned each flood was different from each other in their course of moving material down a drainage. I had my eyes set on two dry washes that produced well for me in the past, both with shallow bedrock. Parked and loaded up my RZR, I headed off to the first location. Donning my gear, I was hoping my Headphones took a charge. My charging light wouldn’t show it was charging, I was hoping the light was just burnt out. Anyways, it was working just fine as I was swinging my coil on the short hike to this small section of dry wash. I arrived, and looked down at my location…it was nearly unrecognizable and was covered with yards of fresh packed dirt. I looked up stream, to see what caused this mess. The wash had such a flow 25 yards above my spot it cut a new channel and layed all the overburdened to the slowdown bend of my location. I still swung it and the new cut to no avail, I’ll wait for the next flood to see if it moves the overburdened…I hate shoveling 😂. Next spot, was perfect! The flow exposed my favorite 10 ft section of Shale. I swung into this area 20 ft above the exposed section to give my 6000 a chance to ground balance. I was eyeballing a spot during my slow sweeps of my 10x5 Coiltek and as soon as I went over the bedrock I heard the sweet sound of my plan come alive. Keeping my eye on the spot, I set my detector down ahead of me it made a familiar tone and I gently raised it up and back down, yes another target. We’ll long story short, I pulled these seven out of the 10 ft section. When I first found this spot many Moons ago it was a good 8” down to the bedrock and produced several 2+ dwt nuggets. Thru the many new models of Minelab detectors it produced other nuggets and I’m sure the 6000 just clean this exposed section out for good. Except now, I’m sure the Gold goes into the 3ft bank of overburdened of the wash on top of this bedrock, I hate shovels! I’ll bank this spot just in case they redesign a shovel into a backhoe! It was late in the day and I headed back to camp before dark. It was a windy night and the morning it died down to a tolerable wind speed for detecting. At my location and 10 minutes in, my detector made a noise I hadn’t heard before! I looked down at my battery charge and it was only down a third. Well it was working fine and continued my hunt a few minutes later the same noise? A few minutes later and my headphones turned off 🙁. I tried, for 30 minutes with just the unit’s speaker and as much as I like the speaker it wasn’t good enough with my worn out Military Hearing fighting against the breeze of the High Plane Desert. Beautiful weather and I hated to leave, got home and found the On-line repair ticket of Minelab USA. Until the next Hunt! LuckyLundy

Well, after updating the software and finding time for a session on the seabed to try out the new scuba program I created, although I have nothing to say about the stability in general, I have encountered a random flaw that occasionally interrupts the audio. Specifically, it happens just after an interference cancellation, or sporadically after changing something between reactivity or sensitivity. In short, you can't change the parameters much otherwise they are indigestible😂. However by rebooting I solved it. Aluminum by the ton and a beach among the most desperate, but at least the conditions were perfect for diving 🙏

As the title says this is a heads up for those that detect with headphones but hate having their ears covered, (that's ME), LOL I have been testing several different sets of earbuds and Bone Conduction Headphones, I love the Bone Conduction headphones but both earbuds and the bone conduction phones do not work properly when detecting with the threshold activated in the Legend every pair of Bone Conduction phones and every pair of earbuds I have tried just would not work correctly with the threshold active in the Legend, (and there is a reason they did not work correctly), but when using the supplied wireless headphones that comes in the Legend pro pack the threshold would work flawlessly, The reason being is the supplied headphones for the Legend are Aptx LL Low Latency headphone the LL is the key to the headphones working correctly. Most all earbuds and bone conduction headphones are Low Latency but they are not Aptx LL Low latency, earbuds and bone conduction phones are just standard Aptx 5.0,5.1,5.2,and the latest is 5.3 these are low latency but not LL Low Latency I have tried many pairs of earbuds at least 12 different pairs, and two pairs of Bone conduction headphones which I do like the two bone conduction headphones the best out of all I tried but, I recently tried a different type of Neck band speaker and I am quite impressed by them so I figured I would share my findings Just received my Avantree Taurus Neck Band speaker and I will say I love these things They are actually APTX Low Latency LL so when you connect them to the Legend you will see the two little LLs by the headphone icon in the Legend screen, just like the wireless headphones that came with the Legend, had no issues with them pairing with the Legend, I hate wearing headphones that cover my ears other earbuds and the bone conduction phones the two little LL is not present by the headphone Icon when connected so they are not true Low Latency LL connections, the Avantree are true Aptx LL Low Latency and work just like the factory headphones that comes with the Legend My main complaint with earbuds and even the Bone Conduction phones which I have been using never would work correctly when running the Legend with a threshold but the Avantree Taurus works great when running with the threshold activated on the Legend I have been on a search for a pair of phones that were actually Aptx Low Latency LL, and these Avantree Taurus are exactly as Avantree states. They are a little different but well worth the try,in my opinion, and yes people will hear what your detector is doing,and saying here is a link to the Avantree Taurus https://avantree.com/torus-nb05-bluetooth-wearable-speaker

After snatching a couple of hours at the day off for a session, I'm back to pissed off today. The Bh-01 headset to which an earpiece had exploded was barely able to transfer sound even at volume 9. Eventually with a gentle current but a constant wave motion, I was forced to look at the screen to figure out what was going on under the coil. That said I am about to set about building a piezo headphone and end of story🙄. I kindly ask anyone who has already discussed this topic, to direct me to the post link for the male connector and positive/negative pole diagram. I saved screenshots a while back, but can't find the folder on my pc. Thank you all in advance🙏

My esteemed pal Keith Southern is a virtuoso of metal detector audio. Not only is he a highly accomplished and respected detectorist and hunter, but he deeply understands and appreciates the audio languages that they speak. I once was so inspired by his insight that I began to link it up with some very limited knowledge of information theory, dim remnants of the "Observe, Orient, Decide, Act" air combat theory as defined by John Boyd which us dumbass USAF Pilot Trainees struggled to grasp, and a couple of glasses of wine and came up with this... The purpose of a metal detectors user interface is two-fold. The first purpose is to allow user control of operating parameters. These include all the well known things like sensitivity, ground balance, discrimination, audio characteristics and visual display characteristics. The second purpose is to inform the user of what the detector is extracting from the target signal. The extremely faint electric currents induced in the target are processed in the detector and presented to the user by audio or visual means. This target feedback information - through the operator’s ears and eyes has one purpose - to cause a “Change of State” of the operator. There is no observation unless there is a change in state of the observer. The energy to change that state comes from the phenomenon being observed. The energy supplied by the phenomenon to change the state of the observer is no longer part of the phenomenon that was being observed. Keith reported that he had good results in specific circumstances with this detector due to its rich audio feedback. The energy given off by in ground targets was analyzed by the detector and presented as a complex audio signal through the headphones. The result was a “change of state” of the operator - Keith. This caused him to either dig or not dig various targets. He was pleased with the results based on his decades of experience hunting similar targets under similar circumstances. There is nothing to suggest that the largely analog single frequency circuitry resulted in inferior performance to more “advanced” machines utilizing digital signal processing instead of analog hardware signal processing. The absence of any visual user information doesn’t really have any relevance as long as the audio information is “conclusive” - that it caused the correct “change of state” of the operator. In the case of a metal detector it would mean desired targets dug, undesirable targets ID as unlikely to be worth digging. To better understand where Keith is coming from in his love of a complex audio interface have a look at his post from December 2016 titled “The Future of detector design will be Sonically aimed” [www.dankowskidetectors.com] Rick Kempf

I've got a Viet Nam era veteran buddy that got Bluetooth hearing aids (very nice) from the VA. He was asking the other day about connecting his aids via Bluetooth to his "Nox 800. Is there a Bluetooth transmitter that plugs into a "normal" headphone output jack on the 'Nox? Jim

I ran a title search inquiry here for “earbuds” in hope of finding low latency Aptx wireless earbuds. I read most of it from 2018 forward. It appears this item is very difficult to find. I have searched Google, ebay, Amazon. No luck. I do not want a neck band or any type of wire leading to the earbud. I am considering a new X-Terra Pro or a used Equinox 800. I want earbuds because of the heat and awareness of my surroundings. I have found multiple Aptx LL transmitters that will work on the Xterra Pro but no Aptx LL earbuds. If I go with a used 800 I can escape the proprietary Bluetooth of the Pro and the 700 and 900 but still need Aptx LL earbuds. Is there a solution for this. Something I have missed? Thanks…

This topic often confuses people and because the details are hidden within specific detector threads people are not aware of nitty gritty details that can help you select the right 3rd party accessories to pair with the wireless audio capability of your detector. First post will provide a link to a great article that provides some background information on BT Audio and explains and tries to clarify some of the terminology that gets thrown around which tends confuse people when they are looking for compatible low latency wireless hardware that will work with their detector: https://www.audioreputation.com/bluetooth-audio-codecs/ This link from a manufacturer of low latency BT hardware explains latency differences associated with some common codecs: https://avantree.com/knowledge-base/general-different-bluetooth-codecs-latency/ To be continued...

I just got a SP01 from Rob. Anyone have a favorite filter setting (1,2 or 3)or setup? I’m using it on a GPX 4500

Wow, I wish I had done this sooner! I got a Garrett WR-1 wireless module for my Axiom some time back, but never seemed to get around to giving it a spin. I use the external speaker most of the time, and the rare times I needed headphones I've preferred to plug in my Sun Ray Pro Gold wired phones. Not only do the Sun Ray have better audio quality than the Garrett MS-3 wireless phones included with the Axiom, but I never need to worry if they are charged. They are always in my kit ready to go. Most importantly, I like dual volume controls due to hearing loss in my right ear. I can use phones without dual controls, but prefer them when I have them. Let's call my 150 ohm Sun Ray Pro Gold as a 10 rating for audio quality. I'd rate the 8 ohm Garrett wireless MS-3 as included with the Axiom as an 8, just very good, not bad, not great. They actually are a good match for the external speaker on the Axiom, as it is hard to really say the headphones sound much different than the speaker, other than being closer to the ear and having sound exclusion properties for background noise. So again, I prefer the external speaker for most use because it has a LOT of volume. For anything else I preferred my Sun Ray Pro Gold. The only problem there is I do want to be wireless with my headphones. Being wired to the detector is a real pain, especially when I put it on the ground. Enter the Garrett WR-1 wireless module, a quite compact receiver for the proprietary Garrett Z-Lynk audio built into the Axiom. Z-Lynk is a 17ms high speed wireless option, much faster than Bluetooth, and being proprietary to Garrett, pairs instantly. Garrett even has a wireless version of their pinpointer that works seamlessly with the system - very nice! The only issue I have seen in that like many 2.4 Ghz systems the signal does not penetrate solid objects well. If you experience audio drop out with the MS-3, pay attention to the detector positioning when it is happening. Reversing the headphone on your head may help, as will setting the detector away or more ahead of you when it is on the ground. I just gave the WR-1 a test run, and I love it! I was worried that maybe the audio quality issue with the MS-3 was related to the wireless signal itself not transmitting the full audio spectrum. Luckily that is not the case. My Sun Ray Pro Gold sound every bit as good plugged into the WR-1 as they do plugged into the detector itself. This is really good news. It means you can go wireless on the Axiom with any headphone you want. I have a couple sets of wired Bose earbuds I really like for hot weather. They work great with a 1/8" to 1/4" adapter - the WR-1 is 1/4" unlike many Bluetooth wireless modules, since it was made especially for metal detector headphone options. Best of all, the volume can be controlled by the Axiom itself since the ear buds have no volume control. Just like the Sun Ray, they sound great with the WR-1, better than the MS-3. If anyone does have issues with headphone/detector positioning and audio drops with the MS-3, this eliminates that completely since you can place the receiver box anywhere. I just stick it in my pocket, but it can go anywhere you want it that the detector cord will reach. The icing on the cake is Garrett makes a WT-1 Z-Lynk transmitter than can turn any detector into a Z-Lynk compatible detector when used with the WR-1. I am ditching my slower Bluetooth transmitter box and getting a WT-1 for use with my other detectors. It's a great system, see the details here for all the various options. And yes, the Garret wireless pinpointer will pair simultaneously to the WT-1 so you get wireless audio from both the detector and the pinpointer through your headphones of choice. I'm saving the best for last. The WR-1 with USB charging cable is only $67.95 and for anyone wanting to convert other detector to Z-Lynk, the WT-1 transmitter with 1/4" adapter and USB charging cable is also only $67.95. Both can be bought together as a package with a nice carry case for $140.95 Anyway, I am totally sold on the WR-1 with my own choice of headphones as being the only way to go, and for any detector that needs it, I will use the WT-1 also. My old White's DFX just went wireless!

Everything works with no noise issue. Trond 2in one receiver and Monoprice Bluetooth 5 headphone with aptx low latency. Total spent 65.00.

When I enter the salt water and the earphone plug / jack just enters the water I get a positive audio response. This is the standard 1/8-inch stereo jack that is directly connected to the pod. If there is a little wave action touching the jack on and off, it responds accordingly. It has stopped me in my tracks thinking it is a target. Once it is fully submerged, it is fine. I tried 2 different headphones T. Eisenhower and the ML Underwater phones. So, no problem with the phones. Never happened using these on the Nox. The higher I am running my sensitivity the more noticeable it is. I presented this to Tom and this was his answer... Once the plug 'wicks'........ the plug will have a film of saltwater on it. Then..................... the next time the plug gets hit with saltwater........ even only the rubber/insulation part of the plug....... it is still "saltwater electrically connected" to the metal part of the 1/8" stereojack........ and you may incur audio squawking. I seem to recall having this with a MXT. I'll look into this on the Manticore. Just wondering if anyone else has noticed this? Thanks Bob K

1st of all I have tried the factory reset and that hasn't helped. The headphones are fully charged. When I try to turn them on sometimes I get a continuous flashing red light. Now when I am trying it I am getting red and blue lights flashing simultaneously. I get no sound from them except when I turn them off I hear them shut down.. Not sure what to do I sure hate to send them back to Minelab

Is it possible to pair wireless earbuds directly to the Axiom for hot weather use? Or is the wr-1 and corded earbuds the only/best option?

hi, recently got my 1st detector the nox 600, and still getting to grips with my new toy and hobby, i am having trouble with getting multiple sets of wireless headphones to show the + for the low latency, even though they are models that other users seem to have no trouble with i have now tried multiple ear buds, and just bought a set of August EP650 which are supposedly aptx-ll, I bought these after reading many threads online, and watching a few videos and the EP650 seemed a popular and financially great buy and all ive seen and read do indeed show this model headphone connected to the equinox range and have the +, so bought them i did, they pair perfectly fine as expected, but do not give the + symbol at all ,tried factory preset/default upon starting up the nox, but same outcome, i probably now have spent on multiple earbuds and headphones more than i would have to get the minelab wireless module ect haha, anyhow could someone possibly shed some light on possible reasons the EP650 just dont wanna play nice on my machine, my nox does have most upto date firmware, but unsure that could cause any issues, but as im new to this, im thinking all possible scenarios , im starting to go a little insane over it
