ИГА-1 Russian Long Range Locator

dragomir привет !!

For antenna best use are massive metal plates as brass , copper , silver , gold or massive metal aluminium alloys plates highly polished like duraluminium D16 , Al-Cu, Al-Si-Cu , or Al-Si-Mg.

Also try to make an feedhorn antenna from same alloy.

Best regards

Yes, that is my opinion. The antenna can be made of various metals but it is important just to be perfectly polished.

A modofied IGA-1 is near to finish....
Here a photo from the pcb (not original but designed by me)

Great work Geo. You are very persistent builder.

Are all chip's (IC's) you need for IGA-1 available?

Hi WM6.
Yes, IC's are available although i made some modifications..., but mdm is the original (yd13).
Also i finished the box with shielding (graphite) and now i must make the power supply and the antenna. Slowly... slowly

[Geo]

Few wires more plus antenna and its OK

Nice progress Geo.
Why you decided for wooden housing. Is it easier for you or some other reason?
Seem original IGA is in metallic housing?

New version of IGA use plastic box as at attached photo. Plastic box was more difficult to me so i used a wooden box ahd graphit spray for shielding.

Geo, this is not new Russian plastic housing design, they only adapt one of cheap (40 EUR) Chinese metal detectors to their needs.

[Geo]

Yes, easy way.
But inside there is the IGA-1.
I don't know what the constructor use for shielding, so i prefered the wood with graphite. My Iga will be about the same as the china plastic.

Do you know which model and brand is this??

Harbor Freight Tools 43149 Metal Detector

I finished the IGA-1. The only that remains is a good adjustment.
It looks to working but there is stability problem. When i press reset meter can't stay at zero more than 2 seconds. Inventor said that must be kept at least 5 seconds at zero position.
I started looking for the problem

Coil seems to be HD disc computer...
