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?

HI,

I would like to present my project under the name of tactics - platform development using new technologies. Here I present the technical assumptions - if I start from the end but what the hell :)


- Lightweight electronics enclosure IP65 membrane keyboard
- Graphical LCD FSTN - readable in sunlight with the possibility of backlighting
- High-quality sensor connector, power supply, headphones and a computer (connector that can be done by software upgrade - degree of protection IP67 connectors - cooperation with probes DD32, DD38 and probe 1x1m Frame Coil- the technology 3TWS
- Modern microprocessor ATXmega
- ADC 18-bit - sensitivity 1uV
- Built-in datalogger memory DataFlash
- Transmitter power 120W
- Datalogger - 5-channel, 21-bit resolution
- 32-bit RTC - time (watch), date
- Cooperation with data visualization software (Excel, Surfer, Taktykgeo 1.0)
- Ergonomic 3 piece construction with aluminum and Carbon black + harness carrier
- Built-in speaker, dedicated headphone
- Power battery 12V / 7Ah

Nice looking board, Taktyk, congratulation.

As I can read on your web site, your detector is already on sale. What are prices in $ or euro?

Are there any schematic or even block scheme of your design?

Power consumption 120W is very high (your battery pack will last no more than 4h). Why you decided for (configuration of) so high consumption?

The current in the coil is 10A, pulse is about 700Vpp :) Power supply is a rechargeable 12V accu, 7Ah - as in lorenz deepmax.

This version was never sold. It is not commercial. Website is my...:)

The block diagram I will show in a moment.

Hello,

The pictures of pcb on geotech look very nice. But you never listed important details.

Can you tell us what PPS, TX width and Delay your detector uses ? As this is for relics, it would be interesting to know.

1000-1200PPS (factory preset = 1000PPS). Sampling delay from 10 to 140uS (for the implementation of size discrimination), factory preset = 25uS. TX width from 150uS-200uS. DSP system can be easily modified through a modification of the software.

Regards

Very nice. What about the coil I.D ? I saw this on the pcb, what does this do ?

It is the identification (ADC reading) of connected coils ->> 13'', 18'' and frame coil 1x1m and other...

The coils have similar characteristics, but not perfect. Identification lets you adjust the system parameters. Setting pramp offset by the DAC..
