Hi guys,

Does anyone know what the headphone connector on the F1A4 plug socket is called? I was thinking of replacing the socket with a standard plug, but making an adapter would be just as easy. Thinking of building a bluetooth mod too, but need the right socket.

Also has any one used bluetooth on an F1A4?

Thanks

James

I think the plug is a proprietary military plug so outside of someone selling F1A4 spares it may be hard to source?

Hi all, I'm new to the forum and fairly new to metal detecting. I started with an Aldi detector and that got me hooked but wanted something to take to the goldfields so I bought a Minelab F1A4, got it home put new batteries in and it worked fine for a couple of minutes then the low battery light started flashing, so I changed the batteries again but it still flashed low battery. Has anyone on here had a similar problem? Or knows how to fix it? I'm dying to get out to goldfields asap. Thanks in advance.

 

[7.62marksman]

what sort of batteries mate

 

[Alex25]

D cell batteries

 

[7.62marksman]

i find on some of my electric stuff if you use cheep ones they only last a few minutes IE cameras
these ore not the best but i use them on the GM 1000 and they seem to go ok -- Duracell procell
i am going to get rechargeable for my gear but will have to get the best (or as close to as money will allow)

 

[Alex25]

I did think it might be the batteries and will try the ones you mentioned, I have tested the batteries I bought though and they are still on full charge.

 

[7.62marksman]

my test and tag machine is like that
the batteries are new but the machine runs for a few min then shuts off however on the battery tester they still show full charge
the ones i said on here last about a month
i got some silver ones top of the range ones and they last me about 3 months but cost an arm and a leg (Energizer Ultimate Lithium Battery AA) think the last price was $25.00 for 4 however i have found them on ebay for about $17.00 for 4
thats why i am going to some good rechargeable ones and carry it in the turtle when i go out

Found a place near me that has the procell batteries, they're actually cheaper than the ones I bought. I'll get some tomorrow and report back. Thanks

You could get a battery mod to your detector so you don't have to use d cells.

Hi Mate,

By the symptoms you describe it sounds like the battery carrier has failed.
There is a power supply in the battery carrier that boosts the battery voltage up to 6v, and they fail.
As long as the voltage of all 4 d-cells is above 3.7v, the detector should run fine.

Keep an eye on ebay, there will be a battery carrier listed up later tonight or tomorrow

Thanks mate, I bought the one you listed I did think that it might be the carrier, but the only one I could find was that other one on eBay for $250 which I thought was excessive. Thanks again
