Amplifier & Speaker On The Cheap? Updated

Recommended Posts

Just ordered these:

41Wr12UoD7L._AC_SY400_.jpg.c51a53fa146c69f6104e50e6d920eda2.jpg

and paired with one of these portable chargers (for example):0084185611215_A.jpeg.f2231a86c1c9752a854edcdabf2a8ac7.jpeg:

am wondering if it will work prospecting in the US Southwest desert.  (If not it won't be the first time I've wasted $10, even this month.)  I'll report back when they arrive, but given it's Christmas rush for shippers it may not be until after Christmas.

Here's a link to a Google Search which shows several places to buy the above speakers.  And just one choice of the USB charger/power-pack of many on the market.

Radio Shack had a  9volt amp, with volume control that many used in the early PI days...coupled with the first coiltek enhancer they made great music together...I doubt you could get either one now...

I would think your best bet would be to use a metal detector, instead.  :laugh:

Seriously, though, are you asking whether they would make for a suitable alternative to using headphones with your detector?   What detector do you plan on marrying them up with?  Seems like a little too much claptrap to have dangling around while swinging a coil.  Apologies if I am misinterpreting your intended usage.

If you are looking for an amplified speaker for detecting check out speakers used for amplifying portable radios. But it would be hard to match the price you paid for those.  What is key is if the frequency response will adequately amplify the narrow audio frequency spectrum of whatever detector you are using without being too bass heavy or tinny.

Yes I still got a couple of those Radio Shack amplified speakers kicking around. Used them on the GP series to good effect. Great for training a small group of people as they went really loud without distorting. The 1/8" inputs were a pain though, and I ended up running a curly cable through the housing and soldering directly onto the board. Never missed a beat after that.

When people ask me to help them with modern tech I tell them "ask someone who really knows -- don't you have grandkids?"  I think Simon is the closest thing we have on this forum to a grandkid.  😜

I've messed a lot with portable little speakers for my detectors as I hate headphones.  This may have been an easier option though for your situation and likely cheaper if you can find it locally.

They're very loud with a good built in amplifier, clear sound, just take normal batteries and last about 50 hours off them and small enough to mount whereever you feel like it.

Believe me when I say they're loud 🙂 Loud enough to annoy JW off in the distance!

$10 w/free shipping on US Ebay.

If you have some of those, do you mind measuring and posting the weight and linear X 3 dimensions?  I'll do the same when my flyer shows up.  50 hrs on normal batteries is probably going to be better in most ways (less weight and longer field life) than my 'solution'.

It would probably work fine, if you can remove the base stands.  Then I would get suspender clamps and secure them to the back of the speakers.  Then you can clamp them to your suspenders or back pack and they will not be flopping around.

      Hi All,
      I am a newbie and purchased a Garrett AT Max. I am having trouble pairing the MS-3 Z-Lynk Headphones to the AT Max. Am I missing something? Manual says push the 2 buttons with headphones on. Did this like 50 times.

      Just got a set of these shipped in 3 days from Hungary.  Perfect impedance match for the N/M detectors--incredible sound.  Very clean and sharp --brings my accuracy up a lot.  They are so loud they need to be run at 8.  I worked with the manufaturer to improve his strain relief system (see the Heyco)--very nice set of phones for these machines.

      Looking for some affordable recommendations for water proof headphones. Mainly want them for the days when it is raining out.
       
      Thanks,

      On occasion, when connecting my Equinox to wireless headphones (either Minelab or SoundPeats), my machine will run the 15 second search with the WI-stream and then stops searching.  The Bluetooth symbol does not appear.  It just runs using the external speaker.   Today, I was going to record this problem before sending it in for repair.  Of course it is now working.  So could it be possibly a problem with being on the beach?  There is much more EMI where I am staying.
