The clone of SUPERSCAN MK II

[kt315]

It is NOT just the coil current but the coil TAU.

[QUOTE=omegamd;193993]The SUPERSCAN MK II was and is my favorite pulse detector potential, but its cost in the market is prohibitive. Because every time I had needed it, I borrowed it from a friend, I decided to make its clone and, after a lot of effort, the whole construction is a fact! Absolutely successful and improved! The cost of the machine from 3000 euros, is down to 300 euros now. The power supplies are improved, along with the preamp of the receiver circuits. Absolutely stable, operating voltage 24VDC (double pulse output from almost all of the machines in market). The performances INTO THE GROUND, are: -With a 45cm coil. -Alloy wheels 1,70 meters. -Plastic box with various golden accessories 90 cm. -Small box from bullets 1,60 meters. Privet ! Helo ! Podlinay plata ? PCB origynal ?

What example ranges on a 2x2m frame?

Hello, I also need this big depth pulse, but I failed to make it twice, can you give me any useful information about it, thank you.

Hi all the experts, can you tell me how to install the frequency control?

I don't think this is a difficult question.

Change the resistor values in the 555 oscillator. There is already a pot that appears to be labeled "freq trimmer."

Thank you for replying to me, is this here? I do not know English

[Carl-NC]

There is a 100k, 270k, and 15k resistor that set the frequency and pulse width. It looks like the 150k resistor might be switched in for changing the timing. Do a web search on 555 timer oscillators, you will see how the resistors (and cap) set the frequency & pulse width.
