Hello everyone. I have a question about designing and building an electronic circuit. My goal is to build a device that can generate and output frequencies from 1 Hz to 1 MHz or more. The reason for this capability is that I want to find gold and buried treasure in the ground and I am building a device that starts generating this frequency in sequence and continues continuously. My goal is to build a device that broadcasts this frequency through an antenna. For example, up to a distance of 100 meters. I would be grateful if anyone has a better idea and can help me in the construction process and if necessary, send me a schematic design and a special board or module if needed. Thank you for your time and help. I will send my Gmail and if anyone wants to help, message me.

The reason for this capability is that I want to find gold and buried treasure in the ground...

Surely you're aware that you're not the first person to seek that capability. There are many companies making a wide range of products just for this. They innovate as fast as they can to stay competitive. Why reinvent the wheel? There's no way you could build one for less than a commercial unit.

If you want the project and the challenge and don't care about the cost and time, go for it. But if you just want to find buried metal, rely on the expertise of experts.

I don't think anyone has a way to find to metal 100m deep but I'm no expert.

 

My goal is to build a device that can generate and output frequencies from 1 Hz to 1 MHz or more.

Buy this generator and use as part of your future device:

$1.97 XR2206 High-precision Signal Generator With Shell DIY Kit
Sine Triangle Square Waves Adjustable 1Hz-1MHz Frequency Range

 

Depending on what part of the world you are located in, there will possibly be government agents seeking to discuss the signals that you are radiating for those distances .
In the USA the radiation at other than very low power levels is seriously regulated, and if the signals interfered with others there would certainly be government agents involved.
For that reason I suggest investigating the rules prior to investing in such equipment.

That's amazing. I had no idea such a device was available so cheaply.

 

My goal is to build a device that broadcasts this frequency through an antenna.

Can you afford an antenna to broadcast 1Hz? A quarter-wavelength antenna for transmitting that frequency would need to have a length of ~ 0.25 * 3 x 10^8 metres (75000 kilometres) !!
You might want to research the radio-wave attenuation properties of typical soil and rock strata to get an estimate of the high transmitter power levels necessary to detect a signal received back from a depth of 100 metres. Your transmissions would be detectable by law-enforcement officers world-wide.

The same signals would also cause quite a bit of interference, and THAT will gain a whole lot of attention. That is not what you want to have when treasure hunting.
I seriously suggest that the TS investigate the actual physics of detecting metals underground. In addition, as already suggested, also investigate what products are already available and understand how they work.

As others have advised, don't mess around with generating your own radio waves unless you know what you are doing. The Men in Black will be on your case in short order. Ground penetrating Radar or GPR can detect buried objects, especially metal, down to maybe 6 or 7 meters depending on the model. You can rent one of those. GPR cannot tell the difference between various metals, say gold versus iron. A high-end metal detector, specifically made for gold prospecting, can discriminate gold versus iron or aluminum if you know how to use it. Beyond that, a magnetic gradiometer (a portable instrument used in archaeology) is useful for finding buried hearths, ancient diggings, and remains of ancient walls and buildings that are covered up by more recent sedimentation. You might have to build your own. As for detecting buried treasure at a distance of up to 100 m across the surface from where you are standing, in the treasure hunting world I've seen claims of something called a "molecular frequency generator" that can detect buried treasure at some distance, including underwater in shipwreck areas. How it works and whether it's even real I don't know.

 

Another detail that is much more challenging than generating such a powerful signal is the receiving portion of the detection system. THAT is where you will come up against the basic laws of physics, which will be a serious challenge.
SO THE TS DOES NEED TO DO A LOT OF RESEARCH AND GAIN SOME UNDERSTANDING.
