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! More QED users reporting in! QED users are reporting that they do not find "bias drift" an issue!
The QED pictured is backward compatible with the current QED and has been designed and made by a member here. The firmware and circuit are identical with the current version except for a change in the face plate and control box. Changing to this configuration will NOT void the warranty when performed by the control box designer as it has been endorsed, approved and authorized by the QED manufacturer. The 4th button will not work at this time as the  firmware update for that has not been created yet and when its available will be provided free of charge (other than postage costs)by BW. QED Detector ,latest updates board is only available to registered forum members.

Goldsearch Australia has been appointed the Australian Distributor for the QED. QED info on the Goldsearch website has been updated.
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 HH is/was basically an experimenters platform with plenty of controls for experimenting with different timing.  Also the HH works well,  especially when you use all the correct components.

Why don't you get your tech friends to design a better detector,  seeing as they know so much  smile

I agree it is a good learning metal detector and i find it works  ,my friends when they design things which i have now understood its best to design circuits with minimum trimmers and such ...if you see the surf pi a copy in many ways really of the hammer head..... parts have been dropped and trimmers down to a few ...looks a better design .

BTW there are no correct components for an experimental device or there would be no reason to experiment ?

I would not ask my friends to design one for me as you would not ask  your friends to work for you ..advice is one thing thats another.

I was just seeing what bolts will work to bracket the real PI case on.
It comes apart ...funny how half a rubber boat oar and a half a crutch fit together so well .
