noisy 7K coil

here's another trick to see if this will quieten down your coil on the 7K.. must admit mine gave me the shits on the weekend in certain places and it confirms it doesn't like damp soil let alone waterproof.

anyhow cut straight to the point--

get a 20 cent piece of stubby holder foam and glue it to the CENTRE OF THE COIL.

Make sure u have cleaned the skid plate and the bottom of the coil prior and once glued in position put the skid plate back into position thus covering the foam and the coil.
Tape the skid plate onto the coil once u have clipped the skid plate back on. Use the proper tape.

This creates a dome effect of the skid plate and bingo--

let me know if this helps. There has to be a god out there looking down.

DO NOT use double sided tape--for what ever reason I don't know.

Hi Ray,
That's interesting mate
I was battling with mine last time I was out, with the 7K going whoo-whoo, p---ssin me off
I'll give your suggestion a go and see what happens
Super glue and gaffa tape ok?

just a very small amount of glue just to hold it in position.

check the gaffa tape out on the detector first to see if theres anything in the composition of the tape that will set the coil of ...I would use glue. match head amount.

Thanks Ray
Can I asked how this idea came about?

Yeah Ray. Me too.

Maybe just a dob of silicon?

Ray, just thinking about your comment on the tape
Just realised that I had gaffa taped the edge of the coil and skid plate before I went out last time, could've been the problem aye?

another JP special I think.

hes always trying to improve the performance and some of the problems that rear their heads.

Hi mate, I did this the other day and used foam tape, sticky on one side, that is used to dust seal doors etc.
Yet to try it out.

SO LONG AS it is in the middle of the bottom of the coil so it domes the skid plate when reattached--this is what seems to be the key.

I've read this somewhere before (on the "Knitting Forum???) - but precisely what noise/problem does it get rid of? Does it get rid of the dreaded "hee haws"?

MAYBE THERES SOMETHING WRONG WITH THAT COIL LES.

maybe a quick phone call to Kevin at Minelab to organise a trip back to the doctor.

hope that helps

That sounds like the same problem I had last time out, heee hawwin

I'll also give this a go, I still think there is a ground balance problem and am waiting for the ferrite which was posted, I hope it makes a difference, but I think it's a bit of a band aid measure, like the foam in the coil trick, another band aid measure.

FFS with a machine that costs $10,700 and a coil which would cost an arm and a leg to replace, why why why are there just band aid fixes to try and get the machine to do what it is promoted to do in the first place.

Sure it's finding small gold, but a mate with a 2300 is finding bits I'm missing because of the noisy ground balance moaning and groaning problem.

cheers dave

at least someone is coming up with ideas to combat the problems that prospectors are encountering..

the car manufacturers could have said that cars with defective air bags can go jump and close their doors but no at least they r trying to fix the problem so fair go I still think the machine is a great piece of equipment and u have to persist with the tinkering of the settings.

the machine has done what it has been promoted to do Dave as far as I'm concerned, however it hasn't performed as well for everyone but at least there is positive ideas coming out of the forest.

sure we all can get hot under the collar but will this solve anything--no--I am willing to give any idea a fair dinkum go to improve the machine. Nothing more nothing less.

I spoke at length with Kevin at ML this morning. He was very pleasant but without testing the machine he was pretty much unable to help and non-committal over the phone. That's understandable.

So, my 7000 and its coil went back to Adelaide today. Cost me 140 bucks in postage!! If it's a bad machine I hope ML cover that as well? On the other hand, if it's a good machine with nothing wrong, I'll probably look like a goose! But that wouldn't be the first time,,,,,,,,,,

So I'm now "7000less" and stuck in Perth until it gets back. BUT - I could trade my spare 4500 on a 2300 and just buy a 14 inch CT Elite for my 5000 and get back out there eh!

Ray - straight swap, 4500 with near new battery for a new 2300,,,,,,,,,and throw in a CT 14 inch Elite for good measure

Now that would be a great test set up eh! Imagine a shoot out between all three! I'd be going mad checking each signal with each machine!

I've just made a reservation at graylands--oh what a deal..
I have a second hand 4500 for $3500 with 4 coils and bits and pieces plus a 5k with 4 coils for $5500.

after serious consideration I have come to the conclusion that stuff it:

take the skid plate of and run the coil commando..i'll let u know what eventuates..

like Les and a few others I want this thing to get up to speed coz in 2 weeks we are headed on a 10 hour trip to catch up with a bloke whom I have never met yet have been in touch with for the past 10 years or so, give or take.

all for a weekend of detecting and socialising.

Ok, ok, I wouldn't wanna rip you off so how about my spare 4500 without the battery, no coil whatsoever straight swap for a 2300 an Elite coil and yer dryblower?

Bargain?
