Nothing too hard even for a rookie technician like me with not so High knowledge on boards whistles and bells...

I'm Just posting a couple pictures at the end of the work, but really (again) misappointed regard the gasket system in the TDI beachhunter.

To give some value to this post, I Just want to Say: please BE CAREFUL doing surgery on this control box, as the plastics are something to severely review to the death White's factory, now Garrett property.

Not only the gasket tunnel between the upper and the lower part of the box is been made to create gasket's cuts and leaks at the first attempt to re-assemble the box, but even a Nightmare to get the job done without the o-ring moving inside and over the PCB when 6 of the 8 screws are already there again....😭.

So this time I'm not so sure to have a leakproof TDI and I swear to want a detector.mod hard case for It.

I Just don't understand why not to create a flat against flat surface with again a flat gasket in between😒😒😒.

White's ...Come on!

(I don't want to advertise for free or without Steve to be ok with these words) so Sorry for complaining with a self exposed solution to this bad thing...

Hello Skullgolddiver. You did a great job.👍

Just want to share one thing we did in the past when we serviced sewer laser. Those laser had a condensate outlet device. That only was a larger screw with a gasket ring. When the laser was serviced, closed and sealed we had to prove tightness. And for that we had one of those screws with an glued in bicycle valve. So a little pressure with a bicycle tire inflator (hand-operated) was given to the housing and then the whole laser was submerged. When bubbles came out you could see it was leaky and where it was, so you could seal again. If I had a detector for underwater usage I'd glue in a valve also. May be first add a srew joint which can be replaced if something happens to the valve. Doing this way I always had a little pressure to the detector housing that would prevent water flooding.

Thanks for your suggestion!Really appreciated.

Unluckily I'm afraid to do other works on this machine as I yet noticed minor cracks around the screws Holes and if not properly handled this Will cause for sure a further damage when in use under real pressure.

Right now I'm chewing some coil's winding procedures and meanwhile I have to calm down my spirits due to the fragile patient I have on the surgery table.

After the add on of a voltmeter and a lithium battery and another coil, I'm back to the original setup with only less cable between control box and coil.

O-rings (circular cross section gasket in a rectangular cross section groove) are engineered to handle pressure.  Each dimension and material composition is carefully chosen.  A flat gasket won't handle the pressure (literally and figuratively).

I don't think it's fair to White's to perform modifications which they never intended the end-user doing and then complain about difficulties encountered in the process.  Or am I misunderstanding what you are doing and the problems you are experiencing?

You're right...

I'm just afraid to ruin anything cause of an easy work for I can't consider to send at the factory the machine especially right now with all the delays.

Unluckily Is not merely a gasket problem, but even the plastics are prone to crack.

I'v used this detector for less than ten sessions and for sure I'll never see the payback time with It.

I Also take in account that I frequently pay the bills doing this and unlikely to an hobbyst, this is a bad ending for me.

This is unfortunate and concerning, to say the least.  We live (and have lived for the past 30+ years) in a throw-away society where cost-cutting corners are the norm.  People (not singling out you) tend to blame the manufacturers and distributors but in fact the public brought this on themselves -- selectively buying the cheap products and putting the quality product manufacturers either out-of-business or scrambling to cheapen their own products to stay competitive.  It's not a complete loss as some companies (including some metal detector manufacturers) succeed in lowering the price while maintaining the quality.  But it's a tough task.

It's even worse when a product's manufacturer is no longer in business (e.g. White's).

I like to tinker also, so I understand your desire and actions to improve your TDI/BH.  But it's always a bit of a risk and I know I may end up with a non-functioning piece of junk. 

I wish you success as you go forward.

I think this is about the plastic quality and the process how it is manufactured. I had the same issues with the plastic housing of the meter pod of my VX3 and the plastic parts of my SpectraSound headphones and the MXT display pod. After some failings to glue these plastics I came across the Epoxy Structural Adhesive >>Scotch Weld DP 410<<. That really did the job and gave new strength to the plastic parts. Right now I have this on all my cracked White's detector plastic parts.

Locator:  Thank you for your helpful suggestion.  My 24k is new (about 6 months old) so I do not have any plastic crack issues.  However, it is nice to know that such products are available should I need them in the future.  It is nice to have this information for reference.  Thanks for sharing.

      I am chasing some advice, I recently swapped my QED PI detector for a Garrett AT Gold.  I basically never used my QED and it was gathering dust and wasting cupboard space which with my growing collection is becoming an issue, I've never gotten rid of a detector before, I even have my first detector from when I was about 9 years old but I decided the QED had to go.  I offered to give it to a friend but after trying it out in my backyard he decided detecting isn't for him as it was too complicated 🙂.  An opportunity came up to swap it for an AT Gold to a guy in Australia who offered to swap his AT Gold plus some cash for a QED, I just took the direct swap with no cash involved to keep it simple so I jumped on it and sent the QED on it's merry way on an international flight the next day.
      So now I have an AT Gold, I've messed around with it and the gold performance is not near the VLF detectors I prefer to use for gold more on par with my other 19kHZ detectors from other brands that also spend their life in the cupboard and nowhere near the performance of the higher frequency VLF's that I do use so I figured I'd get a bigger coil for it for coin hunting, not because I'm expecting it to compete or compare to my other coin detectors but just to give it another purpose as I'm unlikely to use it for prospecting, although maybe the odd creek trip being waterproof might be in it's future.

      It's in tidy condition, the owner was a GPX 4500 guy and in the land of OZ with high mineralisation so the AT Gold was a cupboard decoration for him too.  He sent the Garrett headphones for it too but I have a phobia of headphones so they're stashed away now never to be seen again.
      So, what should I do for coil options for it? The Garrett NZ dealer only has the coil I've already got for it in stock and the 9" x 12" PROformance Concentric Search coil, I am in mild soils so perhaps this concentric would serve me well for coins?
      I prefer aftermarket coils in general and especially in comparison to standard Garrett coils that I've got with my Ace 350, 300i and now the AT Gold, so would I be better off getting a Detech Ultimate, Nel Superfly or Tornado for it? I have both the Ultimate and Tornado for other detectors and really like them and I love that I even have the option of getting these coils with the Garrett as it is one of the things I absolutely despise about the other brand that doesn't allow aftermarket coils.
      I've tested the stock coil on it and the target ID's are pretty poor on my usual coin digs, my Ace 300i with Nel Tornado is giving me deadly accurate Target IDs on deep NZ coins at 6+ inches in depth and the AT Gold with stock 5x8' is all over the place on the exact same targets, very unreliable ID's and won't even detect a 8" coin that the Ace 300i hits on with ease with the Tornado.  Yes I know, big coil, little coil.... this is what I want to improve.
      On Ebay there are a brand of coil I've never heard of available for the At Gold, Magic Coils, made in Russia and they look quite good, Youtube personalities like The Hunter GT have left them very positive reviews but I can't find too much info on them, I'm always willing to try new things though, you never know when you'll discover something special others aren't willing to try.
      Here is one for sale for the AT Gold https://www.ebay.com.au/itm/292834716248?hash=item442e4f2a58:g:ijgAAOSwkB5b~EMv
      So what's my best option from people using one of these higher end Garrett VLF's, Nel? Detech? Magc? or the good old trusty stock coils? if so which one? As at the moment for coins my Ace 300i is flogging it for target ID stability and depth using the Nel Tornado vs the 5x8" Garrett DD on the AT Gold, even on shallow coins the ID's are more stable on the Ace.
      Also, is it worth getting a Nel Snake for it to get a decent little gold coil? I have one for my GBP's and it works well, again no match for the higher frequency detectors I prefer to use, has anyone used a Snake on an AT Gold? I don't expect it to compete with higher frequency detectors but even if it handled hot rocks better or anything it might be an option worth considering.

      Right, this one is a true classic, the counterfeiters in China have outdone themselves on this one.
      It's a cross breed of a GPZ, GPX, Digital Photo Frame, Mp3 Player, Movie Player, Ebook Reader and all metal gold prospecting metal detector all in one.  You name it, it can do it.

      It comes with various colour schemes, one to suit every taste.  The shaft looks like a cross between the GPZ and GPX.  The Arm cuff looks like a GPX arm cuff somehow they've mounted on a GPZ body using wing nuts.

       
       
       
       
      The battery clips look like a decoration.

      The buttons are fancy, I wonder what identify mode is, maybe they've done a ZVT detector with Target ID's! My dream has come true.  A calendar would be very handy while out in the field, don't want to miss those appointments.

      Well, this was my final beach hunt on this beach until after Labor Day. I needed 5 silvers to make it an even 200 from this beach this season. I made it out in the sun longer than I thought I would – from 8 AM until 3 PM. Got a farmer’s tan in one sitting.   😄101 coins including 4 silvers. I did not make 200 no matter how hard I tried. So 199 it is, and I am happy for that, considering the number of visits I missed due to Covid restrictions. I just could not squeak out that one more silver. It’s funny when you stay in the sun digging all day, strange things happen to you on the trip home. Like scratching your back and your hand cramps closed. So, you use you other hand to open it and then that hand cramps shut Dehydration, even with 64 ounces of hydration drinks, just doesn’t cut it. I’m fine now but getting old sucks!      😡First target of the day was the Walking Liberty Half. Then a lull and I knew it would be a long day. Managed 2 nicer condition (and dated) Buffalo nickels. Pictures were taken when it was getting dark, so the are a bit rough. Later I’ll post all the silvers for the season and total for the other seasons combined. One thing I can say about the GPX is that it can find the half dollars like no other machine I have used, including the Equinox. Best of luck to you guys that can continue hunting beaches. I will be rooting for you to get gold      👍
