Hello everyone - we've just spent some time detecting at Clermont . We were told that because we have a GPX5000 we don't need a booster because they have one built into the machine but we talked to quite a few people who are using a booster with their 5000. Would appreciate your comments please if it's necessary to have an additional one. Question

G'day brockster2013,

Depends on how you operate your 5000 if you prefer to use headphones or speakers. If you use speakers then you can use an external booster, but as you have been told the GPX4500/5000 does have a booster built into the battery. The booster only works when you run a speaker which is the way ML have wired it to work. Hope this helps you.

Cheers.

Mike.

The only other benifit i reckon to a external booster is your control of it is much easier then scrolling through the detector menu to quieten things down. For examle the bz has a switch to flick on off basically and a easy volume adjust.
Just my opinion

Mike, Don't know whether it's gospel but I was once told that the inbuilt booster does not work with head phones so as to prevent possible damage to hearing on start up???
1:You plug in a speaker and the inbuilt booster works.
2:Then you plug in an external booster (eg: B&Z) plug in the speakers and they still work, so in effect you have two boosters in line?
3:We have on windy occasions used headphones plugged into the B&Z, is this wrong?

Your views would be appreciated.

Cheers

G'day Peter

When the B&Z booster is plugged into a GPX5000/4500 battery it bypasses inbuilt booster in the battery, so no you don't have 2 boosters, just the B&Z booster, which you can plug the external speakers into, I don't use headphones, I just don't like them.

Thanks to everyone for your replies. It sounds like an external booster may be easier. Regards Graham & Joy Smile

G'day Pete,

I can't really answer this one as I haven't tried the B&Z on the GPX as yet, my son in law has tried to use his with the head phones. I think he said they didn't work properly.  I will ask him next time we call them. Very Happy

Cheers.

Mike.

With headphones on the bz you get a sort of electronic hum or hiss which is a distraction for me. It works but you will soon go nuts or deaf very quickly.

Thanks Dave,
Was a scuba diver for big part of my life and suffered "divers ear," when metal detecting came along and head phones were the norm had to carry a tissue around with me to dry my ears regularly. Qld Sandy posted many years back how to wire up dual speakers and from then on have very rarely ever gone back to head phones, other than already mentioned, very windy days.

If you're getting the electronic hum when using a B&Z with headphones then you need to turn the detector volume down so that the booster volume control will be over the 1 mark, and better still, closer to 2. This gets away from the electronic noise area of the booster. The B&Z is really suited to speaker/speakers as it has a lot of grunt to run them, and almost too much for headphones.
