Just started using my 3030 last week. Did ok the first time I took it out, and experienced this problem but thought it was just me. But now...I dont know.

Here is what is happening. I turn the machine on, let ground balance, and then select my mode and start hunting. Or try to. I keep getting multiple tones, bouncing all over the place. Doesnt matter where I hold the coil, in the air, on the ground, moving or not. It is all over the place. I checked the sens level and turned it way down..not much change, if any. I changed modes..factory modes...did a reset...and still problem. I can hold the coil in the air...and it should be quiet..but I still get noise and tones all over. :minelab::detecting:

I get so many tones, I have a hard time telling if I am getting a hit or not.

HELP....I hope it isnt a physical problem with the machine. I dont want to have to send it in and wait months to get it back. Right now its the only detector I have.

Oh...and it hasnt been left in the sun or a car trunk.
 
This doesn't seem to be right. Contact your dealer first as they may have a replacement. A good dealer would make a fight for you. Minelab has issues with any parts or replacements.

Not the first thing I did...but did check the connections. This is just noisy. Constantly making noise.
 
When you say "ground balance" do you mean noise cancellation? There is a difference between the two and you may be getting electrical interference.Have you tried using the detector at more than one spot? If so and it does the same thing, I would contact my dealer.He can get Minelab to ship directly to you.
 
I did mean ground balance, but I have done the noise cancelation. It made no difference. And yea...I have taken it to different places. Its the same. I have been detecting for years...and this reminds me of the falsing problem that Garrett had with their AT Pro at first.. I dont mind a little noise...but gads...It makes so much noise that I cant tell a find from just a false beep. Very possible it could be the coil...but then...who knows. All I know is that its so frustrating that after about 15 minutes of it I have to put it up for a while...to keep from pitching it.

Contact your dealer. I had mine for about a month now and it runs as smoth as glass. I do get some falsing if the sensitivity is turned up too high. GL and HH
 
I have had that happen 2 or 3 times........After shutting down for a few minutes it has returned to normal.....I have been trying to determin if it happens after any certain sequence of events.......It has done it with both the 11" and 6" coils, so I don't think it's a coil issue or loose connection.......and I have made a point of not leaving it in the truck. We've had a long string of 100+ days here.....

On the lighter side....maybe it's trying to tell me that is is just TOO HOT here in north west MO......LOL..
 
Are you saying you do a Ground Balance each time you turn it on? HH Randy
 
Slide the control box apart and check the connection which you did I see, but turn the 3030 on and wiggle the cable and see what it does. The reason is mine did this and found there was a bad connection in the end of the cable that connect to the control box somewhere as when I pushed the coil wire in towards the box it quiet right down. Another thing to try is disconnect the cable from the control box and if it quiets right down then it has to be in the coil or cable. Being it was new Minelab had me send it in at their expense and sent me out a new CTX3030.
 
Bang on son.......did that...and that is what it was. Quieted down when I pushed it in some, then right back noisy and would get noisy as I wiggled it some.

Thanks much...should my dealer contact them or should I call minelab support?
 
Nope...just when I changed locations. But considering I have only taken it out 3 times...well...I guess you could say almost each time.:rolleyes: As it is, I do appreciate yours and all who have responded. It looks like I have a bad connection on the cable to the control box. Dont know why I didnt think of checking the cables. Something like that is pretty obvious.
 
Glad to see Rick was able to help you get it figure out. HH Randy
 
Yep, thanks Randy. Yea, turns out to be a faulty cable. Not a serious problem, but one that is easy to find...if something thinks of it. I should have after being in comptuers for so many years. I have built more cables than i care to think about and faulty cables at the connectors are the bane of techs. If anything is wrong, that is usually where it is at. Boards sometimes...but usually the cable. And they can fail for any reason. Just being moved slightly...or getting hot..or cold..or pulled on, or wiggled... gads...or for no reason able to be found. Thats computers for you.

It could be the cable there at the connector to the controller....like in mine. So it wouldnt matter if you changed coils or not. And if there is a problem with the cable at the connector, it could easily be susceptable to temp changes. Mine seemed to get worse as the afternoon got hotter. I mean...I was on the beach here in Florida in mid afternoon... White sand beaches...doesnt get much hotter than that. Unless its sidewalks up in NYC or Philly. It could also be that when you change a coil out, you push on the controller cable. Looked at mine and tried undoing to coil connecter and yep..a person can easily push on the other cable some..depends on how big your fingers are. So that could cause problems in the future.

If it doesnt mess with the warranty, it might be worthwhile putting a section of shrink tubing on that part of the cable, covering the connector where it joins the cable. Strengthen it some. Any thoughts on that from any dealers looking in on this? Would I invalidate my warranty if I did that in the future?

Anyway, it was also positional with mine and especially later in the day as it got really hot. But you might to check yours like Rick suggested to me. That proved what was going on with mine. Anyway, good luck. Looks like maybe Minelab might be having an issue with the controller cable that they are going to have to address. Nothing to fault them on though. Cable problems can easily happen, but are relatively easy to solve. Well, easy by strengthening and/or making changes to said cable and then replacing it. Unfortunately for them, it can be expensive. But for what this sells for, they dont have much choice.

You beat me too it.. I had the same problem.. knew it was either the coil or a connection.. good call..
 
Have you looked around for sources of electrical interference? At a park alongside our harbor, my 3030 will sound like a calliope when the yachts turn on their radios and radars. Unless you're hunting an area where targets are very deep, you might try reducing the sensitivity.

I had done all of that. I reduced sens down to 10 at one point. Hardly get much lower and be able to detect anything, except maybe at the surface. And I had problems no matter what location I took it to. The beach...my back yard...the park. Even inside my house, I could turn sens down to nothing almost and have the coil in midair and it would sound off like it was finding a dozen coins at once.

But anyway, Thanks to Ricks help above, I have since discovered that I had a bad cable to the Control box. So its on its way back to my dealer right now and a new one is on its way back. Will have the new one tomorrow. Thanks to excellent customer service.

Thanks for your suggestions though.
 
Don't know if this helps others but I have notice when my air unit(not a Window unit)turns on I get a lot of emi.. Can't get rid of the interference even with noise cancel, I either have to walk away from it or wait for it to shutoff.
 
Radar in particular can be very difficult to shield against because the wavelength is so short that it will fit through small openings. If you've ever watched video crews on military ships the high powered radar gets into the audio signal with ease and even sometimes breaks up the video feed. You can hear the radar dish rotate in some cases and as it comes around there is a high pitched whine in the audio, and the video loses sync for a second. Then it goes away for a couple of seconds and returns as the dish comes back around.
