External Speaker Not Turning Off When I Plug In Wired Headphones


Recommended Posts

Yesterday, I was swinging on Melbourne Beach, which was a mistake, because I didn't realize that they had recently brought in tons and tons of new sand to replenish the beach from Hurricane Irma damage.  Very few targets.
That being said, I was using a pair of headphones with a 1/8th plug. They worked really well with threshhold and other volumes set to counter wind noise on the beach. The problem is that the speaker would sound off as well when any non-ferrous target was swept...and at full volume. Even felt the vibration from speaker.  I also noticed that the headphone icon on the display would momentarily blank out whenever that happened. I'm confused.  Don't want the speaker active when I'm on headphones.  
Any ideas??

P.S. - One coin (clad quarter) for 2.5 hours of swinging! Ugh.  Found a number of small bottles used for drawing medication into a syringe. Hoping it was for someone with diabetes on the beach, and not some other nefarious purpose, like steroids, or other nasties. Pull tabs all registered at 14. screwtops at 17-20.

Yes. The 1/8" plug is not seating well in the headphone socket. I noticed this right away with my 600 and provided phones.

To have the headphone cable hanging out of the detector head is a bad swivel point in my estimation. What I did was put a 1/8" male to male cord into the detector control box, and string it along the bottom of the shaft to below the arm cup, where I tie wrapped a female to female adapter. Now the phones cord comes out of the back of the detector shaft in a much better position for swinging. It is solid enough to put a 1/8" - /14" male-male adapter for other headphones as well.

The way you say that makes me think you are not using the Minelab headphones. Minelab wires the CTX 3030, GPZ 7000, Gold Monster, and now Equinox in such a way that stereo headphones must be wired correctly to cut out the external speaker. Sun Ray makes two versions of the Sun Ray Pro Gold because of this.

The right mono to stereo adapter can solve the problem. Or you have the right headphones and the jack is not seated properly! I did have this happen myself. :smile:

You're right. Was using some Koss phones. 
Not an issue though in another couple of weeks. I just ordered the Mpow New EQ+APP Bluetooth 4.2 Wireless Headphones With Mic CSR 8670 APTX Low Latency Headset for just under $53.00 on AliExpress, shipped.

Some on here have been saying they're even better than the ML-80's coming with my 800, but I'll use the Mpow's on the 600 as well for wireless. In the meantime, I'll go back to the uncomfortable phones that came with the 600 which are On-Ear, not Over-Ear, and with my big head, they ride high on my ears. (Not enough extension...grrr!)

      Got the tarsacci out today to get things charged up and redoing the zlink wires differently. I love the z link and Garrett headphones. But hate the connector that’s needed.  Wish I could figure out something different for that.  Will be in Culpeper in about 3 weeks for the DIV and will only be using the tarsacci there.

      Hello, I am looking for a solution on how to vibrate the Equinox 600/800 detector for a deaf person who will use it underwater. As you know, a deaf person wears hearing aids that are not waterproof and cannot be immersed under water, and in these headphones he is not able to hear the signals, too much hearing loss is about 95dB.
      I did a few attempts with a small amplifier and vibration motor from an old cell phone, but there are problems:
      - after connecting the system to the Nox800 on the cable, the motor makes a slight buzzing noise but does not react to the metal signal in the coil,
      - after connecting the system to the WM08 wireless module, the vibration works great on signals, but unfortunately after the detector is submerged under water, it loses the wireless connection.
      - if I connect the headphone (computer) cable to the Noxa800 and at the end of the handset (the signal is heard in the headphones) I cut the cable and solder it to the system, vibration works great on the signals.
      Why is it that the vibration does not work directly on the cable and it works through the headphone cable?
      Is there anyone on the forum who will cover this topic?
      One more thing. The deaf person uses an induction loop instead of headphones, which works with the hearing aid above the water and on the ground.
      This loop connected to the detector via the cable is perfect, but when it is connected to the WM08, a buzzing can be heard in the background. How to do it to eliminate interference?

      These poll results will be seen at Minelab, in hope of guiding future product development. Please take the poll seriously, and if you wish, provide extra commentary via the posts section.
      This poll is designed to reveal how owners of the Minelab Equinox, Vanquish Pro Pack, and GPX 6000 are using, or not using, the included ML80 and ML100 headphones. Please, only owners of these models should respond to the poll directly, though others are welcome to add commentary via posts. Again, I request you take the poll seriously, and think about answers or commentary provided, as reflecting on the quality of forum membership. Thank you for your time and responses.

      I bought these headphones and used them in the ocean last week in the Kauai (up to my neck).The dealer is always busy or on a trip so I thought I'd throw this out there to get some feedback. I had a few instances where the audio cut out completely and I jiggled the cord and it came back. My question is, should the end of the headphone cord have an o-ring like a lot of my scuba equipment does? The EQ800 still seems to work fine so I don't believe any water made it's way inside detector.
                         As to my success ..well let's just say I understand why my dealer goes to Cancun for his jewelry hunts and not where I went where the waves are 3,4,5 feet. I quickly looked for beaches with "breakwaters" that you can safely take children to and I did find lots of coins and 1 silver diamond ring..but man, it was still 'surgey' as heck and not easy to lift one foot up to push scoop into sand while keeping your balance! Anyone have any experience in using the EQ in the ocean? I saw online sand scoops with a "cross" handle (like on a small shovel) where when you scoop you can keep the scoop from twisting sideways...thoughts..usage?The scoop handle would have to be a "breakdown" type to be able to pack for air travel. The scoop I took has a straight shaft that easily turns sideways when scooping.

      I’m after a durable and lightweight set of headphones for warmer weather. I run a speaker with my 3500 but have the need for headphones sometimes. I want an “on ear” set. I’m looking at getting the Telex Airman 7 Listen Only headphones. The link is below…..love to hear any pros or cons. Impedance is 150 ohms…..thanks.
