At least we can agree on the bang for buck.
Feel free to start another thread to keep the GPZ 7000 defense going.

The Moodz test results are flawed! Look very carefully at his video! Anyway the QED with a 14" mono coil will come very close to his claimed SAD7000 figures and I think would match  them with an 18" mono. And  the QED will do this with almost no interference from EM!
This thread is about the QED so any more posts about the SAD7000 will be moved.

A thread dedicated to GPZ7000 test results would be beneficial.
Consumers always like to know if they have a Stud or a Dud.

The attached pic shows the QED mounted with a 6 cell AA battery holder.
The reasons for the change are as follows.
It has been pointed out to me that the supply of potentially dangerous Lithium batteries is not a good idea for a fledgling Company. Sending detectors overseas that contain lithium batteries would also be problematic.  If individuals want to run the detector from Lithium batteries they of course can but they take full responsibility.
Info can be supplied on how to connect them.
As a result of this advice the QED will now be supplied with a 10 cell charger that is mains or car cigarette lighter socket powered. 12 rechargeable batteries and the battery holder fitted.
One set of 6 cells will last around 4 hours. Alkaline cells can also be used if required.
Another alternative is a battery box that is mounted to the rear of the detector handle that would also serve to counterbalance the weight of the coil.

Can Goldsearch supply a li ion battery pack and charger(mains/12 volt) if requested?

Yes, but people fitting them do so at their own risk
The charger that will be supplied charges the cells individually avoiding the problems of charge imbalance as discussed in the link below.
This provides another strong case for the use of a cell holder rather than a "battery pack".

What chemistry are the 12 rechargeable batteries?

Nickel Metal Hydride (NiMH) would be safer as what the SDC 2300 use except they use a "C" cell size.

I agree. but he only problem with them is their high discharge rate when not being used.They need to be kept  fully charged otherwise they have a shortened life.'
Enaloop batteries could be another possibility?

Okay did some research in regards to both types and their Self Discharge Rate.

NiMH retains 50 - 80% @ 6 months

Lithium retains 80% @ 15 years

Only a problem if you detect once a month. Easy fix, charge before you set out.

OK, so I have already ordered a QED.
What will be supplied? I'm not really interested in a 4 hour operating pack. So I want the li ion pack, is that included in the 1800 I agreed to pay?

I will talk to Dean and get back you you.
The new battery arrangement will give around 8 hours of detection time. Another 6 pack (by putting in fresh charged) will give 12 hours.

The price is being revised down due to the change to NiMH batteries.
I suggest you call Dean tomorrow.

Personally i think any external batteries or external battery packs are a bad idea.

I agree Doug, one of the reasons the QED is attractive to me is getting away from external battery. What about a set up like the whites mxt as pack that fits internally?

Refer to the problems of battery charge balancing.
With a battery pack if one cell fails you throw the whole pack away. With individual cells the failed cell can be easily replaced.

The new safer arrangement offers the same advantage in that the battery lead is very short and can't be caught on shrubbery.

The changes to powering of the detector have been made to decrease the risk factor.

It will still have the problem of charge imbalance which shortens battery life.
If you are in the bush and your Li Ion battery fails it's a long miserable drive home.
With individual common AA cells a service station may have packs of AA Alkaline cells that will save your day.
