Garrett A.D.S. VLF/TR deepseeker with bad sound output???

[Alexcheve]

Do you have a DPF manual of this detector?

Ok here is the pics This is the Master Hunter ADS deepseeker model.

I have just same detector but have no idea how to use it and Garret page is not working or does not let me get in. Hope you can help me with a PDF of manual. Thank you

[Alexcheve]

Please help find a manual

I have same VLF/TR Deepseeker detector as pictured here but I have no idea how to use it. Do you have a PDF of the manual? I tried to get into Garrets but page is not active. Hope you can help. Thanks

"Best to start a new thread". Will do. Thanks!

Hey guys, I just joined the forum. Awesome. I like forums like this. I recently fixed my washer by using a forum with a good tech member. Saved me probably $200. Sweet.

I've got an old 1990 Master Hunter 7X Crossfire by Garrett. Same problem - NO SOUND! It worked fine the last time I used it 2 years ago. Put 6 fresh new batteries in too.

I called Garrett and they would NOT give me the schematic to my unit! Told me to call back tomorrow when a tech named Ed Renner (SP?) was in.

I see Conan fixed his ADS (a little older than mine I think?) and it was the MC14011 IC circuit. Mine has a "14011B X933" 14 point circuit. I'm GUESSING that's the same/similar one? Please note: I have done NO testing and wouldn't even know how or where to start! Electronics moron here - but with potential! I see Big Daddy has a "IC 4011" but I don't know if that's the correct cross-referenced part. http://bigdaddy-enterprises.com/index.htm They have no contacts that I see. My next problem even if I get the part is replacing it. What am I getting into? Think I'd better get someone to do that for me.

P.S. - I noticed that my same model sold at a goodwill auction for $213 recently in 2011. Can't believe it went for that much. That's almost what i paid over 20 years ago. Is this thing a collector's item now??

Best to start a New Thread on this.

Things don't get all mixed up.

There are other test you should do before Pulling IC's.

I would start with the battery compartment.

Start a New Thread!

Thats wrong sorry.I have old notes from the 80's.

2 2 1 1 1 1
2-Never dies.
2-Stays about the same some decrease.

I will do fresh batteries and look for a change in voltage.You can discriminate every thing,but gold and silver with any Master Hunter and up.Ask me for good settings,and mods.

I had a problem with my 6 battery power source.If you just put Batteries into the #1 circuits you should be able to use your MD with headphones.You dont need all 6.If you can find the 4 battery charger unit any 9v works with it.Just dont charge non-recharge batteries.

If you can find the 4 battery recharge pack,try that.Its not in the MD its self.The problem is the battery pack.
This works with Duracell 9v.Take the batteries out after every use.The Master switch is tricky.If it gets pushed to the left it will sound erratic.That is for depth and manual controls.All ways switch to the right for all metal and auto controls.This will search for every thing and you can still discriminate.
Sorry for all the edits

[homefire]

Yep! The Problem we talked about was NO AUDIO!

you have another Beast.

Ground Bal, Discrim set wrong? Garrett has never sent back a machine to me not working.

Try , Try , Try again.

Was it working good before hand?

If so, tell us more.

ADS DEEPSEEKER

Hello Ralph sorry I have not responded sooner but I was away on a trip looking for Gold nuggets since the price is so high at the moment any size is worth finding.It's hard to relate your problem to my Deepseeker or gold dredger because yours,the sound is not dead (as you say) the sound is there but dies when you go over a target.That sounds to me like(ONE) the ground balance is not set right and you are too far to one side that is out of the ten turns you have you are too far to the left or too far to the right.Try different types of metals air testing them,like silver coin or ring and gold ring from memory go all the way to the left then go clockwise three turns that usually balances black soil,but picks up Gold and Silver.(TWO)If that's no good then check your voltage 36 volts for circuit and 9 volts for sound."But since you got it tested by garret that should be O.K .(THREE) Some capacitors are a bit lazy in line with the transistor we are talking about.My bet is more likely the ground balance side or a simple capacitor on the audio side.Mine was completely dead other then the battery check so it was a lot harder to pinpoint.Thanks to Gold Dredger and Homefire for the help with the schematic and pics.You can use any 5pin Grounhog coils for the Deepsseker they have the same wiring numbers and pin five does nothing.Red is Red Black is Brown White is clear and Earth is Earth.All you need is to wire a small cable with a male 4pin plug and at the other end a female 5 pin plug.Mine I have five different sizes.But anyway that's another story let us know how you go.CHEERS EVERYONE

Ticked at Garrett

Hey Guys.
Well, I finally got both of my detectors back from Garrett while I was out of town on business. Got home late last night and couldn't wait to get out today. Guess what? The ADS Deepseeker still has the same problem as when I sent it in to them. I've got a nice new battery tray, but the sound still dies out after a pass over a target. I spent over $100 for shipping and "repairs." I'm so mad I could spit. Of course, when I called, Garrett had already closed for the day. Man, I can't wait until Monday - are they gonna get an earfull !!! That will make me feel better, but it won't fix the detector. OK, back to Square One.
I'm gonna try to get one of the replacement parts that Homefire, Conan, and Gold Dredger replaced. Homefire, I guess I can use NSDU45, or MPSU 45 or CENU45 from what you advised Gold Dredger - is that right? Gold Dredger, if you have time, can you circle where that part is on the picture of your board and re-post it - PLEASE ?!?!?!?!?! Thanks again guys. Never send away what you should try to fix yourself (at least once anyway !!!
Can't wait to try out the ADS 7 tomorrow.

Ralph

[homefire]

Unlike MineLab, Garrett will have them back to you in a week or two.

Cost will be shipping and a little.

Let us know how it went.

[Gold dredger]

Hey there is nothing wrong with that. I cam every close to doing the same thing then decided what the heck I will give it a go. Let us know how it goes.

[Pappydoodle]

Thanks guys. I talked with Garrett this afternoon. Since I'm not really experienced with this type of repair, I'm just going ot send them both in. I know, I know . . . chicken, coward, etc ,etc, etc. But I really don't want to lose either detector. I'll let yopu know what I get back from Garrett.

[Gold dredger]

Yes they are the same. Swap out that part and you should be back in Bizz.

[homefire]

There the same! CEN-u45 can be used as well.
