Oops.....”leaked” My Tdibh

Recommended Posts

My cleaning regime after an ocean detecting session is meticulous but I got a little careless when I got home.

i always rinse the unit really well at the beach showers and always look for signs of water ingress immediately afterwards and everything checked out fine.

When I get home, everything is submerged in a long plastic tub full of warm fresh water where it soaks for about 15 minutes. I also add some mild liquid soap to help get all the salt out of every knock and cranny. I normally add the soap to the bottom of the tub and then blast the water in to get it mixed up......and THEN I place the detector in. Well today, I got careless and placed the detector into the bottom of the tub first and then for some unknown reason, proceeded to fill the tub with heavy water pressure.........yep........the force of the water got past the orange gasket and forced itself into the detector body. Luckily I noticed it straight away and no damage was done at all. I did have to disassemble the whole unit and dried it all out completely. Not too much water got in as you can see in the third photo. The biggest hassle is getting the gasket back on and securing the 8 screws evenly otherwise the gasket can bulge out in a few places.

Lesson learnt........go easy with the water pressure when using the snap on hose connector. I’ve only made this mistake once and didn’t get away with it. 
Anyhow, now you all get to see a disassembled TDIBH. Interestingly, the battery compartment is  completely separate from the electronics top half. As far as a waterproofness weakness.....it is the orange gasket but only from high dynamic water pressure.

 As you know fresh water 🚿 water is no big deal but that salt water will make your detector history.

 Years ago I dropped a Whites detector in a stream and it went under. I quickly picked it up and water came pouring out . I disconnected the batteries right away and then went to my car . I started it up with the heater going full blast . I had the back of it so the hot air was blowing in .

 I wasn’t sure if that detector had not past on to where ever detectors go when they die . After about 20 minutes I stop the car and connected the batteries up .

 Here is the rest of the story. I gave that detector to a friend and now going over 40 years that detector is still working.

I was in Lake Michigan with a White's IDX Pro and a big wave hit it. The detector stopped working. I turned it off and laid it out in the sun all day and it started working again. Shouldn't have taken it into Lake Michigan to begin with so be careful with your detectors lol.

Yup, my Minelab Go Find 40 was dropped in the lake by my daughter when she was using it, fresh water obviously, it completely went under while switched on. She got it out pretty quickly for a kid but it was in there for longer than I'd like 🙂  She switched it off pretty quickly, surprising she knew to do that.

We just drove along holding it out the car window for 20 minutes to get back to the caravan which looked to have dried it out, then we put it's control pod in a plastic bag with some uncooked white rice and rubber bands holding the bag over the pod.  Switched it on the next morning and it was working fine, still goes fine to this day a year later.

Good lesson for a youngster.  Most adults wouldn't know to do these but your daughter will remember for the rest of her life.

Why did they remove the bottom of the pots? Why didn't they just use sealed waterproof pots.

To make sure any water ingress does not soak the circuit board. Get some soldering sponge. It expands when it gets wet soaking up any water.. You want to place the sponge(s) in the box at the lowest level of detecting angle. This is where the water will travel to due to gravity.

There is a trick getting the top and bottom of the case together easily.  Don't put any silicone grease onto the o-ring until you set it in place.

Added note tighten the screws that hold the case and top together too tight. The mounting tabs  that hold the nuts and or screws  in place will crack.

Thanks Sven

Not sure about the pots but I made sure to only tighten the screws to slightly compress the O ring.

      Hello everybody on the forum, hello Steve!
      I am a relic and coin hunter in Europe. Among other detectors I have used Minelab pulse machines since 1999, so I have a small arsenal of Coiltek and Detech coils for SD, GP and GPX models. ... and now I have set my mind to owning a White's TDI SL as well. I heard and read that Coiltek and Detech coils for SD, GP and GPX models can also be used on the TDI.
      Is that true??
      I'm looking forward to your answers! Take care and good hunt!

      Not trying to clog up the forum with ebay item(s), but this looks like a hard-to-find item someone here might want:
      ebay.com/itm/18-Cannon-Coil-For-Whites-TDI-Metal-Detector-/2
      Never seen one of these myself and have never heard of this company (if 'Cannon' is actually a company name -- maybe it's not).  Says 17 microsecond or longer delay is recommended, which takes it out of my wheelhouse since my TDI/SPP is locked at 10 us.

      Have a mine lab gpx 5000 and ordered a whites tdi sl for a backup unit a friend told me the gpx coils will work on the tdi?? But it’s not here yet to see if they will even plug in to the whites , so what’s the truth ??? Thanks

      Which do you think will hit deeper on wet sand?  I'd prefer a TDIBH over a DF but I'm budget limited.

      I've had this coil for quite some time, but it was packed away and forgotten. It was purchased for A$60 because I was intrigued.
      It is the anti-interference version. Measures 12 x 4 and uses the MInelab lower rod.
      Weight is decent, build quality is good. Performance in the field still remains a mystery as I've yet to use it. I gave it a quick air test just to see how it behaved on the Tdi Pro.
      This version has a hot spot in the centre of the coil which appears very sensitive to small targets at shallow depth. Seems to hit fairly well at shallow depths but doesn't have much punch for the deeper targets. Test garden results on coins would give real world depth on coins between a solid hit around 15cm or 6 inches and fading fast past 20cm or 8 inches. 
      Useless air test with ground balance off, gain at max, in ALL, frequency in the middle, pulse delay at 10.
      1 grain was               7cm
      .5 gram gold coin  16cm
      1/2 Sovereign         23cm
      Us Quarter              23cm
      Aussie Penny         25cm
      Whites Buckle        33cm
      So in summary it hits hard on small and shallow targets, the centre of the coil is a hot spot for sure.. Fades fast as depth increases, the big Whites buckle just managed 13 inches.
      Since I managed max gain on the Tdi Pro in an EMI hot zone, the Anti-interference feature seems to work ok.. One of the things I like about the Tdi machines is the ability to plug in all sorts of coils, never know if you don't have a go..  My Tdi SL is highly resistance to EMI and the Pro less so but still very good. This coil could make more sense mounted on a Minelab around electric fences and mobile phone towers.. etc.
      All the best,
      Karelian
