QED coming soon!
Goldsearch Australia has been appointed the Australian Distributor for the QED.Check their website after  Wed 7th Dec 2016.
Global temperature goes from heat record to heat record, yet the sun is at its dimmest for half a century.
What is empirical  evidence?
Empirical evidence is information acquired by observation or experimentation. This data is recorded and analyzed by scientists and is a central process as part of the scientific method. Why is everything posted on climate by Inhere always horseshit?
Poor old  Inhere on finders still does not know the difference between weather and climate!The silly old goat seems to think because some places have recently had very cold weather that this brings into question  AGW!  Only right wing rabble rubbish climate deniers like horseshit Inhere don't  seem to understand  that AGW will mean that some regions of the earth will become colder!
Why is  onehalfgram :1/2 wit always wrong  on the QED?

The attached pic shows a 128*32 pixel OLED display that is hooked up to a QED for development.
The top bar graph shows battery voltage.
the middle 2 will show the digitised value of the short TX and the other the long TX.
The bottom dot graph shpws the combined signal with center zero.
It can be used as an aid to GB and also provide visual target strength for the deaf..
The dot should be in the middle and not moving when detector is GB'd and the coil raised and lowered to the ground.
Falling pitch short TC targets will cause the dot to go left and vice versa.
For size scaling the pins to the left side of the board are 0.1" apart.
Two larger 128*64 pixel modules are on the way from China allowing adjustment variables to be displayed also.

Nice visibility at sunlight.

Is it possible to display chosen parameter at whole display or in lines only?

It's only experimental at this stage.
The screen is very small, 1" diagonal so may not suit older folk with poor eyesight.
It doesn't come with any fonts, just 128*64 pixel graphics.

That is a good idea Mr. Bugwhiskers.  That way we folks that are getting older by the minute will be able to see the display when it comes out on the market.  Thanks.

BW is currently working on the firmware for the  OLED display and integrating the screen  hardware into the QED circuit.
