Another satisfied QED user! QED user report for 9 days detecting! User loves it, found it easy to use,found gold with it and he prefers it to his 5000! Also a report on a QED used at the beach for coin shooting.QED users reporting in with their multi ounce gold finds with the QED!
From  another QED user today:"Been out and about today testing and comparing against other machines etc in ground that has been horrible in the past.Bround balancing Ive found very simple and easy.'m using the Nokia booster but need a little more sound/threshold.Otherwise no complaints from me, very impressed."
and :"My QED with the 8” commander on it, out performed my SDC Got bits that don't register on my scales SDC has since been sold"
"My QED is terrific. Lightweight, very sensitive and screams at me when it hits any target. The Detect shaft and the 11" ultra sensing coil is a top quality fitout. I attached an external speaker which added under 200gms of weight in total and still remains very well balanced so i never feel fatigued after many hours of swinging."

Stinky  Pete :http://www.detech-metaldetectorsaustralia.com.au/ is the  Australian distributor for the QED.
This is the only forum where you can talk directly with the designer/ manufacturer of the QED and  also some very experienced QED users.
Jrbeatty and Reg Wilson  and  Yellowfin  (or Doug here for that matter!)have NO vested  or pecuniary interests(or secret deals or cash for comment or any other undisclosed benefits )in the QED other than using it to find gold which it is doing very successfully! The ONLY people deriving  an income from the QED(other than finding good gold) are the approved retailer and Bugwhiskers! The ONLY investor in the QED is Bugwhiskers!
I have never met Jrbeatty or Reg Wilson at Howards house or ANY other location!

The links below show the ideal battery charger for the QED, 240v or 12v car charge 12 NiMH batteries at a time.
Yesterday I performed an endurance test and with 2 * 6 (12) ALDI AA NiMH rechargeable batteries the detector will run from 9-10 hours. 24 batteries from ALDI, enough for 1 set and a spare set will cost just 6 * $5.99, a measly $36. I have used ALDI NiMH for many years I can attest to their longevity.

  

  

Pics of the battery box and its mounting along with the stand and external amp/speaker attachment will be posted in a few days.

All NiMH batteries self discharge. The ENELOOP battery sought to minimise this.
The solution is simple, charge in the car on the way to your prospecting patch and have the spare set charging ready for your return to the car at lunch time. I have purchased around 30 batteries over the last 4 years or so and have never had to throw one out.

Could people use these batteries if they wish? But much more expensive.

Anyone know much about Kentli batteries. They have a rechargeable Lithium AA battery wired to 1.5v they claim that the batteries have a capacity of 2800mWh which matches Eneloop Pro but are lighter. More expensive too.

If the spec of these batteries are to be believed then on a full charge they should give 2 days detecting? I think the current draw of the QED is about 400mAH?

The attached pics show the NiMH solution.
2 layers of 6 cells in series, each bank with its own protective fuse.
9 - 10 hours of detecting time using ALDI "AA"s
Alternatively, a triple pack of Li Ion can be installed with a detection time of up to 21 hours using 3250mAH cells.

If required, additional "things" can be fastened to the outside eg external speaker as shown.
The side can be swapped to suit left handers.

The Grunt box.
Slightly bigger and can hold up to 12 * 18650 Li Ion batteries in 2 layers separately fused for safety.
If the cells are 3250mAH - over 40 hours of detection time.
It will also work with only 1 cell on each layer.

Seeing double.

The dual layer 9 - 10 hour detecting time inexpensive & safe solution.
The fuse clip can just be seen at far left.
To change batteries:
Remove 4 wing nuts (no tools required)
Remove lid.
Slide green connector away from it's partner.
Lift pack out. (tipping upside down works well)
Replace the 12 batteries.

The ebay link to the external speaker.
It contains 3 AAA batteries and runs for around 15 hours.
