CZ70 PRO

[DigitNY]

I recently bought from 2 separate members, a pair of black widow DP Headphones, and the CZ70pro, I think I'm having issues with the speaker on the detector, some times just get very low sounding tones or nothing, to regular operation. Now I think the problem has been exacerbated by a pair of headphones I thought were going to be super loud(as I can't hear to well) to barely audible headset. Really frustrated, any help with the speaker problem on the CZ ( anybody dealt with this before) or hints please let me know. It's been a 3 weeks since I bought the cz and didn't get to use it a lot, being that it ran ok the first time., I told the seller everything's good. Unsure what to do ?? Same with the headphones, just bought them a week ago, used them on my minelab 305 and they were ok,( not great) but told the seller everything's alright.

Wheels I don't think the problem is in the headphones, but the volume control inside the CZ70. One thing you can try is a contact spray which I forget the name of. But the guys at Radio Shack will know it. You can use a Q-tip and clean out the plug jack on the 70 and wipe clean the male jack on the MD's. If that doesn't help you need to send in the MD. Them Black Widow's are great.

. So the contact spray I would imagine, you spray on the headphone adapter ? I hope it works, sounds better than the alternative, gonna have to send the seller an email, can't imagine he didn't know about this. Thanx again sandman, always appreciate your help!!

At first thought, and without sufficient information, the first question is, "is the volume low on both the headphones AND the speaker?".

If so, then your detector internal audio output would be hurting. This means that somewhere along the line there would be a voltage drop, or a bad connection. And that can be caused by a dirty connection (as Sandman indicates), or an internal power supply fluxuation. WD-40 is mostly water, so putting a drop inside on the contact points will not hurt anything at all, and it REALLY cleans things too. The spray that Sandman speaks of is mostly compresssed air with a shmidgeon of solvent in it, and is commonly used for those occasions, but WD-40 works better and a little bit of it (one drop from an eyedropper, but not more) will not created a problem with electron flow or resistance, nor will it deteriorate any synthetic parts if used sparingly. Just wipe off the excess from the drop of liquid, and the rest will dissapate over time and not hurt a thing even if it does not cure the problem.. DO NOT SPRAY IT THOUGH! Put some in a small cap and use the eyedropper.

On the other hand, if the speaker does better than the headphones, then you may have a loosened female receiver (where it plugs in to the detector). OR, you could have a loosened male plug too. OR, you could have a speaker connection inside the headphones loose from abuse or misuse somewhere along the line..

Now there is more to consider; If someone was too brutal plugging something into the headphone jack, or unplugging it, that alone can cause the exact problem you are having, because rough treatment loosens and weakens everything. Those jacks are not as tough as they need to be. MY CZ70 is as loud as a freight train, and I wouldn't need headphones even if a Sherman tank was rolling by, and I have ear damage in my left ear.

From your statement, it appears that the problem is inside the detector, and not the jack nor the headphones either. You had audio problems (before) the new headphones, even before you plugged them in. It narrows it down to an internal detector problem, so it should go back to the MFG. If it were me I would fix it mysef, but a novice should not fool with something like that, it could leave you ready to use a hammer on it and out a whole lot of $$.

PS: DO NOT use WD-40 on house current, high voltage, high wattage, high amp, or anything that can be used as or is designed to produce light, heat itself, or heat anything else. The same thing is true about Radio Shack's spray cleaner(s), both types.

First off, I just want to thank you for all the technical advice I don't think thier is anything else I could possibly want to know, without sending it in. I'm going to carefully! Give that a try, then either send it in, or get the seller who sold it to me three weeks ago to admit he sold me a bum unit and return it. Larry , thanks again.

Whatever you do Wheels, keep whatever you or someone else has done to it when or if you send it in. Some techs are a bit touchy about people doing unauthorized work on their creations, and the repair price could reflect that...

Nope..I'm not touching it.

Well I decide to try to just put a little wd40 on a q-tip, clean the jack and see what happens. Well, nothing same old problem as the first time I turned it on. Low volume, cuts in n out...impossible to use, unfortunately I didn't bring my minelab, so it ruined my day. Not to mention I looked like a very unhappy customer on a local beach, the expletives were flyin, It just sunk in, the whole situation. I'm really pissed off and it's nobodies fault,.but the guy who sold it to me. Thier is no way that a speaker just went overnite or as a result of anything I did, this seems like something that occurred over time. Either way theirs no way the seller didn't know, I should have been suspicious when he didn't leave his phone# in the email. Everybody I've ever bought anything from, via email,ecspecially something of value,..always left thier phone #. Ill give an update, hopefully he does the right thing and I can move on.

Well, there is another possibility Digit. When shipped, it is possible that the speaker inside the detector got jarred enough to loosen the wire connections, or, to crack the circuit board, or to dislodge something else inside it, i.e. loosen the contact points on the battery holder, etc. If when speaking to him about his sending it, ask him if he insured it. If he did the two of you can gang up on the parcel delivery establishment that guaranteed it. If not, then it is between you and him, although if you paid for the damage insurance in the price and it says so on the work order, then it would be writtten as such on the paperwork. If so, then all you have to do is to contact the insurer and show them a certified copy of the order, complete with proof of the contract with the insurance cost included. If the seller refuses to answer or return your calls, then by his silence he is making a clear statement of guilt. If he lives close enough you can collect for the damaged merchandise via small claims court, find out where he works, and collect through insisting that he do so or else you will have his salary subjected to claims. Bosses don't appreciate their employees running out on a bill, and they don't like their payroll being disrupted either, it costs them money too. Larry

Thnk you for the advice, I really hate drama,..so this is the worse possible situation I could find myself in. I just hope we can come to a amicable agreement. Sooner the better, would like to put it behind me. Again,.. thanx for all the input.
