Can you post more details of origin.
Hope you never paid much for this.

Looks like rubbish construction

I cant understand you.
First of all this 5008 is cheep china VLF.That is almost 100% identical with Magnum.You have TGSL use it.
From what you describe you have some kind of GEB or shielding problem.If you still wanna waist your time with this toy.Then try to investigate GEB sector.
This is only my opinion.But you havent posted detailed info.
Wish you luck.

Hi,
hmmm...

you just lower it to ground and it sounds/detect that ?

If so.... you have much probably a bad shielding (as explained above) or a bad wiring to shield.

Unless you have VERY mineralized soil and worse ground balancing (it's unlikely I think) you cannot experience that on such kind of MDs.

I think you have to inspect wiring of coils/shield and coil itself if needed.

Not easy, I know, cause it's assembled unit... so you can broke stuff... but if device works so bad there are very few alternatives... I think you cannot gain easy any service for it (both for location and manifacturer of it): these are sold as is... most of the times... and just occasionally if someone have troubles can gain (very not official) service from tech guys... e.g. from people that have service of tesoro/whites etc... I mean, skilled in MD repairs, but that as favour from them... cause I don't know these cheap chinese made clones have ANY e.g. warranty or something.

If so... and you can't get service by qualified people, you must do yourself... no other way.

You can also be conservative... e.g. try to make a brand new homemade coil for it before messing up with original coil... then if works can try to fix original or reuse its container/fixing stuff etc

From my point of view it's a difficault task... cause few it's known about these clones... and if don't identify exactly the model cloned making a good coil could be really challenging starting from scratch.

Of course, can measure resistance, inductances... make proper nulling and shielding... but... not sure you'll end up with a better coil then.

But it's worth you try... what to lose ? Nothing I think.

Kind regards,
Max

It certainly sounds like there is a fault with your detector, Since it is a new purchase I suggest that you return it to the place where you bought it. Either ask for a replacement or your money back.

Depends "where" he bought it.

I know people having these similar cheap stuff... they got them but sold as is by a company that sells by mail orders and the like... one resulted broke at coil, the man asked for money back or replace with new one.

But company who sold it never answered emails of him.

So he's stuck with a broken one.

Depends... not every dealer is serious... nor in any place these dirty cheap things can be "serviced".

I usually avoid that "companies" cause are well known troublemakers... if things are fine... ok... but if something goes wrong... well... lose money, nervs, time... etc

Better buy at e.g. some electronic / hobby shop... pay 20euros more and can throw that in their face directly (joke, of course ) if they refuse any replacement or money back if defective unit.
With emails... people easy run away if don't wanna reply you.

Kind regards,
Max
