Waterproofing Minelab coils help?.....

[Big Red]

I hear a lot of people complaining about "all minelab coils not being waterproof", but very little on "how to waterproof one"? I would think sealing between where the bottom and sides meet, with marine grade silicone, would suffice? Not sure about where the coil meets the cable on top? Seems like you could squeeze some down inside of the strain relief? Would that not waterproof the coil, or am I missing something here, I don't know about? Thanks.....

Which coils do you have? Just about all of the non-gold machines have waterproof coils from the factory. Most of the aftermarket coils are waterproof too. I don't know if I'd trust trying to waterproof a coil that wasn't made that way to begin with. If I had to do it for some reason, I think I'd either use the liquid bed liner stuff or some tool handle dip, depending on whether I ever wanted to be able to remove it!

Ditto on what cuda said. Personally if I wanted a waterproof coil I would purchase one if I didn't already have one.
To me trying to waterproof a non waterproof coil is risky, if it shorts out due to water intrusion it could damage the machine, hence a coil is cheaper in the long run.

Yeah and I agree, but when they don't make any (except the 15 incher!) for all 3 of my 4 "Minelab Gold Detectors", the XT18000, the Klondike and the American Gold Striker, they have either the 9X6 (5?) coils, or the 1000 coil, which, I am told, are not waterproof? So, what else am I suppose to do? I know, don't get it wet, right?.....Dirty trick by Minelab, to make a non waterproof coil, on a gold detector. Bunch of crap!
I guess the only one with waterproof coils, of the 4 is the 705? Wait, forgot one, I also have a Eureka Gold, think that one is also not waterproof, the 9X6/5 coil? Some of these might use the 1000 coil, but think that one, might also not be waterproof?. Hell, how do you tell, since no one has a list of waterproof/non-waterproof Minelab coils? The only waterproof coil(s) I own (for minelabs!) is the 15 inch for the Eureka (Think that coil maybe also fits the XT18000 and the Klondike) And possibly both the 705 coils (10 inch concentric, 10X6 DD) Hopefully, I can rely on them being waterproof!.....
Minelab needs to come out with some better coil choices (and waterproof!) and not the $200.00-$250.00 variety, like the aftermarket coil manufacturers are making?.....

I think you need to trade them all in and get the new GPZ7000! What do you think of that idea?

 

[Big Red]

Ha,ha, yeah, they might all make a downpayment on that GPZ7000, but they sure won't make much of a dent in paying it off? I will have to check that unit out, so thanks for at least giving me somewhere to go!

Big Red, if anyone would know I would suggest Doc. Perhaps giving coiltek a email or what not might come up with a solution for you.

the 10.5 double dd coils from minelab for the xterras are NOT waterproof the stock concentric is. this is the only minelab i know about though

 

[JunGun]

Well BigRed,
I got a GPX7000 to play with, maybe you want to invite me up there sometime? I will be in Trinity county Cali and El Dorado detecting for the next 2 months. Maybe sometime towards the end of summer I can head up there

Hell, how do you tell, since no one has a list of waterproof/non-waterproof Minelab coils?

Minelab is really accessible! You can call Minelab and talk to a tech and they'll tell you which Coils are waterproof.
Best of Luck!

 

[Backstrap80]

I've been calling all morning. Do you have a special number? Been dealing with a broke 705 for 3 months.

i have to test the GPZ 7000 underwater and see at which depth I'll loose $10K ! (this price is outstanding for this product, they make a mark up of $9500 at least on it).

Concerning the coil, more then water it is dust, sand and salt which is the issue. From my experience, when you have a leak on a coil: it is dead. The waterproof coils from Minelab are :

Sovereign / excalibur range, and CTX coils. If I was you I will take a look to the Coilteck coil range, most of them are waterproof in VLF.

[frogmaster-riviera]

You always need a Waterproof coil... in case you need to detect in remote locations...

Would enjoy that, but my plans for the summer are kinda made, like yours are? Keep you in mind though, if they fall through? Thanks and wow, that's a lot of coin you spent, hope it is worth it and you find huge one pound nuggets with it! Let us all know how it does on the tests you will put it through this summer? Really interested in that, thanks again.
