Thanks for the reply, I've ordered it now and the battery life is what attracted me to it.  I need long battery life as my detecting days are a minimum of 12 hours.  I'm hoping it can drive external speakers.  I'm also hoping Steelphase makes a SP01 at some point for the task :)

Thanks also Blip, that one you posted lasts 8 hours and the more expensive one 10 hours.  Getting there.  The one you posted also says Adapted headphone impedance: 10-150ohm, the GME external speakers are 8ohm so I don't know if they're going to play nicely together.

If I buy from Aliexpress the Chinese seem to have ways around batteries and shipping, they can do it no issues.

If Pat's intending to make a new SP01 for external speakers that will work on the QED I'd be in queue to buy that as I am certain I'd rather use my SP01 than a normal headphone amp, it's worth the dough.

I ordered that 9v guitar amp in the meantime, I might gut a X-50 and try that out too, thanks for the idea Howard.

Maybe I just need to fork out the cash and buy this one, 12 hour battery life... that's more my style

  


It drives headphones easily and earbuds also.

Regarding filtering, the QED has digital filtering for both pitch and amplitude. This is a major contributor to it's EMI rejection. If you watch comparison videos of the SDC2300 and the QED it jumps out.

The EMI rejection on the QED is outstanding.  Very handy in an area where the gold fields tend to have power lines all over them :)  Lots of department of conservation land protected for its outstanding natural landscape, but great to run high voltage power lines from the hydro dams over

The QED audio socket is Stereo but L&R are shorted as the audio output is mono, not stereo.
Metal Detector audio has been a hot topic for many years and lots of boosters and other gadgets have come and gone.

Jas, bugger all these days mate. I got shafted with some LED chips as i was modding lamps and AliExpress wouldnt support me. They supported the dodgy seller so stuff them. There is some good stuff on there though. Ive bought alot off there over the years. Like you say some stuff is sold through the likes of Supercheap for a huge markup. I like how some people say they wouldnt buy that cheap junk but are unaware they are buying the same stuff locally at a huge markup!

Well my Guitar amp arrived today, the 9v battery one

Using the AMP I can now use the SP01 If I go QED / Guitar AMP / SP01 / External speaker.  It's a bit of a mess of cables though.

I'll mess around with my Quest Wifi and see if I can now find a better solution using the guitar amp.  If I go QED / AMP / Quest wifi then wifi to the SP01 and then extennal speaker I maybe able to be cord free from the QED again which is my aim, I won't use it if it means I'm attached to the detector with cords.  Hopefully that works.
