Potential Leak & Condensation Issues With Beachhunter Boxes & 12” Coils

Recommended Posts

For a number of years I was a cable splicer and cable repairman with the phone company I was working for.

 A splice didn’t have to get wet from direct rain from a hole in the sleeve covering the splice. You also have to deal with atmospheric pressure on the outside and inside of the cable. That small hole can act like a soda straw sucking the moisture in . To avoid from this happening you try to keep the cable pressurized.

 When a cable does get wet you have to open the splice up and you start dumping in the desiccant. It came in 8 oz. can and it was nothing to use 6 cans if not more to dry out the splice. As you were drying out the splice you could feel the heat from the drying action from the desiccant. When you knew the splice was dry and as you wrap up the splice you added one more can .

 Desiccant can’t adsorb but so much moisture and after that it’s exceeded its usefulness.

 In my opinion if you have bags of desiccant inside the case they need to be replaced each time you open the case . The container the desiccant comes in the lid always needs to be on good. If not it’s usefulness can go flat and become worthless.

 If you could suck out the air each time and then pressurize with nitrogen gas this would stop your problem.

Yep....I have about 50 silica gel sachets. Self indicating which means they change colour as they absorb moisture. All kept in an airtight container until needed and baked in the oven as required and then reused.

Just maybe White’s needs to take a hint from other detector companies and have a complete sealed unit . The only trouble with this idea you couldn’t play around jacking up the voltage.

 You can send in your BH in everyday until your warranty runs out but unless it’s re-engineered it will be a problem.

Like someone said that the electronics and battery compartment should have been separate.

 The sad thing you can send it in until they give you a new one but your problem really  hasn’t gone away . 

I know I repeat myself over and over but the customer got the short end of the stick on this one.

The issue is being played up too much in my opinion. The Beachhunter ID came out in 2001 so 18 years in production. They’ve not been dying right or left or we would have heard more about it by now. Leave the battery door off when not in use, and keep fresh silica gel packs in the detector. A little blow in the door with a hairdryer won’t hurt things. Forewarned is forearmed.

But yes, designs like the Fisher CZ-21 where the circuit box is totally sealed and separate from the battery compartment are superior in my opinion.

Wonder if they could encapsulate the circuit?

is an example of one product I know of.

They should have included a vent plug in the design of the box? So after a hunt when stored, just open the plug to let any moisture escape. Would also allow for some equalization of pressure.

      I have decided to finally swap out my big 12” Dual field coil on my TDIBH for something smaller. The purpose is to use in the water.
      I have some pros and cons with each model so feel free to add any ideas you have.
      Coiltek Platypus 12x8. Waterproof, epoxy filled. Maybe too long on the 12” side which sees the most water resistance Detech 8” Mono. Foam filled so more buoyant but not too worried as 2/3 the size of the Dual Field coil. Good size. Waterproof. Garrett 8” Mono coil. Waterproof, epoxy filled. Good size. Suitable for lower delays? Garrett coil

      I was on my way back from a detecting trip near Winnemucca.  I stopped in at Armadillo in Grants Pass, Oregon and saw this hanging on the wall.  Apparently, there are only three in existence.  This one belongs to Sam.  From what I understand, she received this for being the top salesperson in the company with this model.
      I think this would have been a way better color than the original black!

      On the TDI Pro the upper handle was a bolt on assembly with separate part numbers The prototype models has a straight shaft, and the production models an S shaft. In either case you could remove the handle via four bolts to hip or chest mount the control box.


      Since the production models went S shaft, there were aftermarket straight shafts. Here is the Anderson aftermarket straight shaft  for the TDI Pro:
      https://www.seriousdetecting.com/product/anderson-whites-tdi-metal-detector-black-carbon-fiber-shaft/

      Does anyone have any part numbers for the original TDI upper handle?
      The SL models the handle does not normally separate (attaches from inside the control box) and so only White’s or White’s dealers would have access to the part number for the upper straight shaft or S shaft.


      The straight middle shaft 500-0288-1 or S shaft 802-5213 is standard on many whites detectors, and there is a “tall man” version 500-0240-1 of the S shaft.
      Does anyone know or have access to part numbers for the handle on the TDI SL, either straight or S shaft?
      The TDI Beachunter uses a removable shaft that can probably be retrofitted to the SL models with some drilling.

       
      This appears to be the White’s Diver Rod Kit, part # 802-5195-1, with straight middle shaft 500-0288-1 added, and may retrofit to the SL with some drilling.

      White’s Diver Rod Kit
      One of the best deals going in a rod assembly for years has been the Whites Space Saver Rod Kit for Classics and Early Goldmaster models, part number 802-5236. This may also retrofit the the SL and is in any case a good way to get some Whites Rod parts cheap. While they last.

      White’s Space Saver Rod Kit
      If anyone has any information they can add about any TDI model rod or shaft parts, now would be a great time to archive it while it’s still halfway easy to track down.

      Started like a boring session this morning...
      Everything ready to do another underwater footage of mine but as usual, almost nothing can be done right as we want.
      Camera's battery dried up after 3 hours...Coins and garbage at some serious depth with the Tdi...After five hours, leaving the beach really destroyed, the last signal heard with died battery on the machine was the wedding band buried in few sand but too old to be a fresh drop.🤔...Clueless find even today..
      So this is the only picture to show...
