. Hopefully Detect-Ed/SeaGhost will also whack a Deus II plug on them..

Hello Erik,

You can probably get Deus II headphones from Seaghost. At least you can ask...

I recall that he was experimenting with Deus II a while back.

As Skully mentioned, the White's TDI BH was a great option for jewlery hunting, except for the coil, which was big, floaty, and not swappable.

A couple of years ago, we, a group of PI enthusiasts, inspired the Ukrainian manufacturer Seaghost to design the bulletproof housing with the option to swap coils.

One machine was modified and delivered (it is up for sale in Spain).

But the plans were interrupted due to the Russian invasion. My own TDI was not finished, and it was left in the city of Mariupol.

Looking for an oem housing or to have my 600 converted... thanks!

Hi, you could get your oem housing from seaghost if you want to. Just get in touch with the manufacturer on Instagram. You can pay via PayPal and he will ship your housing worldwide (with a couple of exceptions).

On top of that you could re-pack your equinox in seaghost housing by yourself, just check a couple of last videos from the Instagram page you see in the post you're quoting.

Hi, KurtInRI

I routed the cable inside the shaft of my waterproof ETRAC. 

please find some pictures following the link, I hope it is self-explanatory.

(I used original etrac shaft and DIY 3d printed parts)

I am using TDI BH under water for a couple of years now. 1,5 years back the could leaked, so I got a replacement of complete detector.

Future plan is to do some serious waterproofing:

Hello Joe, great job.

Plastic head ip68 pushbuttons are not so good quality. You definitively have to check this one:

Switchcraft Series 913 Sealed Push Button Switch. It is IP68 rated when mounted on a panel.

It has a great built quality and a rubber boot to seal the momentary switch.

Ibhave used these in my etrac build back in 2015....

What is your opinion of the waterproof headphones supplied by Sea Ghost?

Very loud and well-built. Coiled cable is soft.

I considered this mod in my first equinox 800, but finally I sold it and get a new one... Only for the warranty. 

Those who have the SeaghostMod, what can you say about the Equinox for diving? Anyone compared it with Excalibur?

Thanks! 

This eq mod is not really for diving, but you can easily take it 10m deep. Headphones a pretty loud.

Can you show where the charging cable attaches with and without the cable attached?

Bad news, S.g.diver. water is inside, so you really have to check the circuit board carefully to see any damage.

One of my whites TDIBH went to the service and was change by new tdi past summer. 

No water inside, but unstable threshold and falsing... Suspected coil leakage.

These machines turned to be rare nowadays, at least my dealer got rid of all whites products due to Whites shutdown.

The machine to have would be the TDI Pro in that box...SEA GHOST has really done some nice mods over the last 2 years.

It is nearly impossible to get one TDI pro in Europe, Joe. A part looks like TDI pro would give little benefit to these who hunt snorkeling or wading, because even TDI SL reacts quite much on the surf, so you have to crank up pulse delay to get rid of false signals.

Thanks for info. It's boyant, I know. I counterweight it rather than open. Don't like to modify coils....

The mod was not done by me, by the way. But yes, mainly because of me.

Observing my TDI Bh, ... and the aftermarket Detech 8")..

Speaking on 8" detech coil. Any problems with water leaking inside of the coil housing?

I have mine somewhere. Not tested yet. Waiting for new fancy TDI like this one:

Here is one i bought not long ago.

Telescopic rod is a good compact solution then you don't do a waterhunt. This one will be done in salt water in just a couple of hunts....

Right, they are 3 x 18650.

The charging and USB connection is done via headphone connection (using some extra pins).

New battery is roughly twice the capacity of the original one.

I am Ukraine born, but currently located in EU. 

Unfortunately the EQ kit is not DIY type of product, so you have to ship your detector to Ukraine. Ones the modificación is ready you are getting back ready to use equinox along with a charging cable, waterproof headphones and the grip.

There is the same story happen with vanquish: you have to ship it. There are some soldering to be done, thus kit is not suitable for self installation.

Although some older housings (explorer/etrac series) were suitable for DIY assembly.

Different installation variants are available. Here is my EQ600 (pot is made by seaghost, the rest is done by me):

I own a couple of these modified equinoxes. The acrylic housing looks and feels just great.

Feel free to ask your questions.

Here you have some close up photos:

Right, cables are coming out the sides because the overall design is made for these why snorkeling/diving with the detector. Here you can see the mod much better:

There is no too much space incide the display unit. I can't see the way to do reliable connection for the headphones.

Your story is a good example why I am not a fan of any stock underwater detector.

Then it fails, you have to sell It for small amount of money and get yourself a new detector, but the story will repeat in some years. There is no easy way to source parts of the housing for repairing it by yourself....

That's the reason I have started my waterproof etrac project back in 2014. I am literally able bare hands open and fix my detector straight at the parking lot at the beach.

All parts except PCB itself are manufactured by me, so no problem with the spares....

I have never had any of CTX, so all this are just my thoughts.

CTX main board is located in the upper box. There is a cable connection that runs from the box to the display unit, there the loudspeaker is placed.

So you just have to figure out which pins are responsible for the loudspeaker and wire these to the stock headphone connector. 

And that's it.

You will have stock looking CTX with amplifier output.

Sure, the headphones has to be replaced by the custom ones (>= 8 ohm).

Should I've been selling this idea instead of giving it for free 😉

The connector is neither a problem. It should be M12 8pin type. You can use amphenol plastic one or brass one from chinaexpress.

My Sea Hunter MK2 doesn't have a menu or volume control 😞

Understood. ... is quite complicated then. Especially if you use it for diving.

I heard somebody did the amplifier for infinium, but I have no further info on that.

A volume control would be nice too.

For batteries, have you checked out the off contact rechargables like they do with cell phones? This would allow you to completely encapsulate the board and make it truely waterproof.

There is no need for the volume control ones you can do the adjustments straight from you detector's menu.

Both posted examples got lipo with a charger. The connector got a couple of extra pins for charging purpose. 

Both posted examples are fully waterproof.

Have You tried regular speakers instead of piezos in your projects?

I'm actually interested in that type of headphone, due to the kind of sound they can give.

Yes I did it three or four years back. These are headphones I'm using nearly everyday for snorkeling and diving.

Let's see if I can post a link.

The link works! Such a surprise, this is a first forum i see that allow to embed a link from insta. thanks, Steve, for such a great forum!

Adding....

There is no need to do the amplified headphones for CTX, ones there is amplified output available inside the detector: the loudspeaker output has built in amplifier, so you can hook up you headphones to this output, SGD.

I did it some year back for my waterproofed Etracs and forgot about weak sound problem.

Here is another example. 

This is one of my old project to amplify piezos.

The tiny PCB is the amplifier powerful enough to be used in a boombox.

Sonitron is the manufacturer....

Everything is possible, allthrough it is always good to k.i.s.s. 

Here is amplified EX headphones from the friend of mine. 

He is using a cheap amplifier from chinaexpress.

The phone itself is a membrane sealed dynamic head.
