There is some applicable information in this thread:

A Dual Field coil would work as well. Here is a link to my YouTube build:

thanks a lot surfdetector for the informations.
Q: can i build double d coil at the same way you build dual field?

They are different coils.

@Sallahkhan,,,Whch pcb are you connectng it to? The early versions don't have the pcb connectons for a 'DD' Coil. Can you post a pic of your board? Regards, Marty.

[Sallahkhan]

yeah i know that, just what i want to said to connect them in series as you did that's all

[Sallahkhan]

Hi MartyJ1963... it's a new version of Mirage pi made by Elliot called GoldMax i didn't get it yet i'll put it on as soon as i received it.

Hi Sallahkhan,,,It's ok,,I have already made the Gold-max but I have only used a Mono coil with it so far. The build file supplied to you by Elliot shows you what connections to make if you use a 'DD' coil. You will have to balance the coils (null) and I thnk each coil has its own damping resistor. I'll check my archives to see if I have any other information for you but I also think a 'Dual field' coil (as suggested to you by Surfdetector) will work better with the Gold-max than a balanced 'DD'. You will be able to wire this coil to the 'Mono' terminals of the Gold-max. Regards, Marty.

[Sallahkhan]

Really! thats sounds good, how did you find it? what's your rating of Gold-max? could i use it to detect mountains and sahara?

[MartyJ1963]

Hiya Sallankhan. The Gold-max is a very sensisitve detecter. Even with the 3DSS Mono coil it detects very clearly at 12-14 Inches. I have never tried any other coils with it yet though,,I am yet to find time to experiment. I don't know the mineralization of your are but it should be great for sand. Regards, Marty.

[Sallahkhan]

It's very kind of you to give me informations, thanks for everything Marty. Can i ask last thing, did you make the previous version of Mirage ULTRA MDDSD? if so, could you please share with me the manual if you don't mind?
Regards, Sallah

[MartyJ1963]

@Sallankhan. They were already posted on another thread. The build file is too large to post on here but if you PM me your email address I can send it to you. Regards, Marty.

[Sallahkhan]
