Vibration For Minelab Equinox 600/800 For The Deaf


Recommended Posts


You should be able to use almost any waterproof headphone unit and add a couple of led's to give a visual indicator. Be sure that you waterproof your work when done.

I have done it on some underwater gear that I use as a backup to the speaker for it, and it has never failed yet.

Just be sure to pick a color that you like and make sure that you use a circuit that will not burn up the outputs.

Not. I have hearing aids, but they are not waterproof

Bone conduction headphone can be wireless or wired and vibrate through the cheek bones. There are water proofed versions too.

How about using a shrouded bright led so it can be seen in bright light?

This way, I can miss interesting signals, I would have to look at the LED all the time.

I can't find such waterproof headphones

To start, I have never used this type of headphones. I know someone that does use a wired brand of bone phones when metal detecting in areas where he wants to have full situational awareness and wants to hear his surrounding area with his ears. He does not have any hearing issues. He has used them either plugged directly into the Equinox control box or plugged into the WM08 module. They work well for him.

So, first, if you really want to keep your Equinox (totally understandable) I would start out with a wired set paired with your WM08 and see if they work for you for general detecting. There are wired supposedly waterproof versions listed on both Amazon and eBay currently. There are hundreds of wireless models listed too and some are waterproof. However, they do not appear to be APTX Low Latency. I am not even sure if that matters with bone phones...........? Personally, unless I was wearing a wet suit head covering or some type of waterproof tight fitting head covering, I would be afraid that bone phones would fall off when snorkeling or if I was hit with a wave. That goes for any type of headphones underwater. Also, I would not dive with an Equinox. I would only use mine in shallower and calmer water, not rough surf, but that is just me.

Here is a link to a wired version by a well know company.

The added vibration mod in the Polish YouTube video was great added to the Excalibur. Something like that could be added to an Equinox. However, I am going to repeat.....I would not dive with an Equinox. Yes it is listed as waterproof to 3 meters. There have been far too many reports of the Equinox control box not being waterproof to 3 meters or even 3 centimeters. If you want to work underwater, you should be using a detector that is specifically made for that. The Equinox is very versatile but there are far better detectors for diving than the Equinox especially in saltwater. As another poster mentioned, I would buy a Nokta Makro Simplex (US $254) or the Nokta Makro Pulse Dive (US $160) which both have built in vibration instead of diving/snorkeling with an Equinox. You may spend more than that just to get vibration on your Equinox.

I see the problem here. The Equinox uses electronic switching to determine if headphones are plugged in, then it mutes the internal loudspeaker and drived the headphones.
It measures the load placed on the Right channel, that is between the 'ring' and the 'ground' of the stereo plug. My experiments show 50 Ohms or less is needed to trigger the switch-over circuitry.
Probably the simplest method for you is to short the 'ring' to ground, and use the Left channel ( 'tip' ) to ground as your audio source.

I think the WM08 module would work underwater if it were placed very close to the control-box, so there was minimal water between them. The radio antenna in the control box is along the top edge, centrally positioned. The WM08 would probably need to be fitted into a watertight enclosure, I don't have one, so I'm unsure of it's water rating.

I can't help much with the loop / WM08 issue. The module has stereo output, is it possible to use both L and R to drive the loop, either by directly joining them, or with a pair of low-value resistors ( under 10 Ohms ? ) to isolate L and R.

Is the loop a low resistance ? Perhaps a series resistor may make it easier on the WM08.

I connected a mass resistor with the right channel, the motor rotates slightly and when there is a signal on the coil, it vibrates strongly, only it bothers me that the motor vibrates slightly.

I have already dipped the Equinox 800 several times and everything is fine, I know that in deeper water in the lakes there are signals, but you need to know what and at what depth on the bottom. I plan to do so up to 2.5 m in the vicinity of the bathing beach and piers. Hence the need for vibration. I have Simplex + nice machine but not everything, Nox800 yes 🙂

      Curious if the Legend is compatible with the Pulse Dive pointer and maybe the Green headphones. Anyone know?

      I was experimenting with Dan(MN)'s mod of mounting the WM-08 to a pair of good quality wired headphones, which works really well. I read the Equinox manual section about the WM 08 and saw that its latency is only 17ms whereas Low Latency Bluetooth is 40ms and normal Bluetooth is up to 100ms.
      I have been using LL Bluetooth ear buds all Summer and Fall so I'm used to the way they respond, but when I tested my new WM 08 rig, I couldn't really tell any difference in response time/latency. I guess I was expecting there to be a noticible difference.
      So my questions are, for those who use the WM 08 module, can you tell a difference as opposed to Bluetooth? Do you prefer to use the WM 08 setup and why?

      So I did a little more experimenting with the WM08 and various wired headphones I have around the house and I am noticing a little difference in latency VS Bluetooth, specially with pinpointing as suggested in responses to my previously posted WM08 question. I also noticed quite a difference in sound of different headphones when used with the WM08 too. I've been looking into some of your suggested headphones, such as Gray Ghost, Sunray Gold, Killer Bee, etc., as well as looking at older posts regarding headphones for use with the Equinox.
      This leads me to ask a question to those of you who prefer wired phones with your Nox. What full over-the-ear wired headphones do you prefer with your Equinox and why? TIA for your help.

      I noticed that these don't come with a volume control.  Is that because it's harder to hear under water and not needed?  Would I be better off with a pair of Amphibians from Detector Pro?
      Thanks!

      Who has run the sp01 on their  6
      I had a crack , with my cogs as well , but found the cables a pain in the arse ...
      Also with the 6,s headphones on 70% volume on the phones and the detector backed off a tad  I hear the feint murmurs ok I reckon anyway 😃

      I had some spare time today and was messing around in the man-cave. I've had a pair of Audio Technica ATH-M50X that I had used with the WM08 last year.
      I've been plugging wired earbuds into the WM08 and running the cord down the back of my shirt to keep the cord out of my way.
      I have a couple of APTX Low Latency transmitters I used on the CTX, Etrac etc and was going to use that on the Audio's.
      I was having a hard time getting them to pair up, when I glanced at my WM08 and had a flash of inspiration The Techica's have a special twist in, removable plug, so I decided to make a short patch cord and mount the WM08 on the side of the headphones.
      These phones have some excellent sound quality with more than enough volume and they feel great. I retire this Saturday, so I plan on giving the setup a good work out next week.
