The battery is ok but, it maybe the speaker or some other connection.

It has static at times and cuts in and out, even when it is clipped to the arm strap on the detector, I have narrowed it down to the WM12 as even when it has headphones plugged in it still does the same as when they are unplugged and with a booster and external speakers it does the same whether they are plugged in or not.

Is there a way to check if it is just the WM12 speaker or something else inside it.

It looks like the actual speaker is a replacement part? and would hopefully be cheaper than a whole new WM12

Any ideas?

So for now I am just plugging the booster and dual speakers into the back of the 7000 near the battery, but after getting used to being unteathered  by cables it is just a bit annoying when you put the machine down and go to retrieve the target. 

cheers dave

It will be the stereo jack, WA dirt gets in there and they wear out. Give it a good spray with some contact cleaner and rub out with some paper towel and a cotton bud to see if that improves things. Can’t be the speaker because it gets disconnected when you plug anything into the jack. Also try using the reset button on the WM12, I’d doubt if it will help but is worth a shot before plumbing for a new WM12.

Thanks JP, I'll give that a go and report back.

It's a lot better, not completely right yet, so I'll give it another go with the cleaner and a cotton bud.

JP was right then, you'll be able to solve it, this stuff is brilliant for that.  Jaycar have a similar product, not quite as good but does the job not much help to you in WA's outback though I guess. 🙂

It has a small nozzle attachment to spray it right into headphone sockets to flush them out and dissolves dirt and grime and won't effect any electronics.  It drys very quickly.

Yep all I had was WD40, so I held the WM12 upside down so the fluid wouldn't run all down the the whole thing and basically just spray in with the tube attached to the nozzle and it then could drain out and rubbed around the insides with a cotton bud.

You have to be a bit careful with WD40, it can attract dirt and dust over time so can make things worse, at the moment the benefit will be it washed the dirt off by being a liquid rinsing it.  A good electronics component cleaner will wash the residual WD40 off when you can get your hands on some.

You might be able to get this in the outback somewhere, the version of WD40 for the job

Yep, thanks Simon, yes I will do that, and in the mean time I am hoping the careful application of WD40 will help, I am hoping that by spraying it in with the module held upside down so the excess drains out and the the cotton bud to wipe around the inside.

Hi all. New to the forum but been out in the scrub for 6 years. Brought a 7000 3 years ago and going well. With regard to the WM12 I get a loss of reception through the wifi from the machine and the speaker if that makes sense. If I am searching through a spoon full of dirt to find a nugget, while scraping along the coil I get a blanking out of all sound. Not all the time but you do need to check the spoon a couple of times just in case before throwing out the soil. I have found in my use that running the spoon on the rear edge of the coil seems to give the best and loudest response. No idea why.

Cheers, sturt

      Clearly, with the huge amount of interest that is being shown in the after market coils for 7000, it`s obvious that there is a market out there for coils other than 14'' and 19".       I don`t take the 19" out much because I have had very little success with it and with my bad wrists it`s just too damn heavy, but Minelab did tell us in the early days of marketing the 7000 that they would be releasing a 11" coil down the track, and now there is another company that nobody has ever heard of making a huge range of coils that are lighter and have so far been very well received by the public.
      What`s going on Minelab?

      A couple of months ago I put out a call for the parts list for the WM12 because my original WM12 was taking forever to charge.          At the same time I bought the replacement battery, I also bought some heavier charging cables because I have about half a dozen devices that all use the same cable. I bought cables that were listed as suitable for external hard drives and they were about 6 bucks each. Because I kept changing cables on different devices I don`t even know now what cables came with the WM12.         Anyway, with the heavier charging cables my original WM12 now charges QUICKER than the newer WM12, so I don`t need to fit the battery.        Maybe, if your WM12 is getting sluggish charging, it may not be the battery, it may be the cable breaking down.   Just a thought.    Dave

      I really don't want to spend $150+ on a set of  waterproof phones since I don't do a ton of water hunting.  
      Anyone tried these:  https://www.ebay.com/itm/LS-PELSO-WATERPROOF-HEADPHONES-FOR-USE-WITH-MINELAB-EQUINOX600-800METAL-DETECTOR/273858263213?hash=item3fc33978ad:g:CIQAAOSwIbtb6pHb

      Hi Bill, Salt is always going to be a problem, especially if you want to also achieve depth. Deeper targets are slow responses, salt signal kills slow signal responses. My advice on salty areas is to try your most sensitive modes first and go down from there, in this instance it would be High Yield, then General then Xtra Deep Normal before I changed any of my other settings.
      Your Threshold is too low, stick to 27 especially if Audio Smoothing is in the Off position, I would also recommend using Semi Auto mode because Salt signal messes with the Ferrite Balance in Auto mode. 
      There is a huge difference in Salt signal if you go from Normal to Difficult, this also might have been a good option for you dependant on the ground in your area. A lot of people shy away from Difficult especially in quieter soils because there is a perceived depth reduction, however on Half ounce nuggets Difficult actually gives a better signal response than Normal does in any of the Normal modes (HY, Gen or XtraDeep). 
      Minelab introduced the Ground Smoothing mode in the last update, this mode was specifically designed for Salty ground conditions, essentially they are Motion filters so there is a depth reduction when you select either Patch or Salty mode so I tend to avoid them but it does smooth the machine out a lot.
      Finally, having a controlled swing speed helps immensely with Salt signals, try not to suddenly vertically lift the coil as this exacerbates the salt signal immensely. To confirm it is salt signal just lift the coil from detect height to abover your head, as the coil transitions from your waist height to shoulder height you should hear a moaning sound, the level of salt signal is determined by how loud this response is. The other way is to place the coil in the air out in front of you with the coil parallel to the ground then rotate the coil from left to right and listen to the audio response, the greater the noise the greater the salt levels. This will help you to decided how aggressive you need to be in reducing sensitivity via the Gold/Ground type Modes or the use of the Ground Smoothing filters.
      Hope this helps

      Gidday All,
      Managed to get two hours in today before rain chased me home with the 17 inch Russian X coil.
      Blew me away just how good this coil is ! I purposely picked a small area of State forest that I have flogged for the last 10 years, with all 3 different GPX detectors, with coils from 11-25 inches, the SDC, and even a QED. This spot has yielded many ounces of gold to me from 0.05g up to 33g. I had declared it " dead ", as my last 10 or so efforts with the standard GPZ14 and GPZ19 have yielded nothing more.
      2 hours in today, nearly back to the car, and I get an obvious signal. This was slightly downhill from a small patch of small reef gold, in an area that I have literally smashed.
      Coil was about 2 inches above the ground because of sticks and clumpy grass. Removed said obstacles and signal firmer. 4 inches in and I am in nice gravel, target now screaming, out pops what turns out to be buck shot. Bugger, but this is from a spot that I have NEVER managed to get a target in ! 
      Moved about 10m along and same thing, another obvious target, once again coil 2 inches over the ground. Dug in and same again, 4 inches down in nice gravel, target screaming louder than the buckshot, out pops what turns out to be an 0.65 gram bit of reef gold ! I'll be buggered, I thought ! 
      Rain then chased me home.
      Coil was very sensitive, being able to pick up my 0.11g test piece at 2 inches. I tried knocking the coil against a tree a few times and no bump sensitivity. 17 round weighs the same as the GPZ14. All in all, a fantastic coil. Don't know what the Russians have done differently, but Minelab need to have a good hard look ! 
      Further testing to come when our shitty weather finally breaks.
      Cheers, Rick
