A detector for red soil?

[ZOUjiarui]

The felezjoo pi can't work on red soil, it keeps barking, and if you turn down the sensitivity, it loses depth to the coin
And surf pi pro, which doesn't work on red soil, which is like an iron gate.

Please help me, what kind of metal detector is suitable to work here? god scan 4？
Thank you very much.

You need a PI with ground balance. See this thread for info:

There may be other threads on PI-GB designs, try doing a search.

The felezjoo also has a GB, but it shows the presence of iron at short intervals, broken machine, I took it apart.

In a subtractive GB PI it is critical to match the delays in the two channels. If you don't there will be ground noise.

The gold scan 4 may
There is also a super scan, which has two coils instead of GB, which would be great if it could, and it has depth and anti-mineralization.
There is also a DBP 2010, I don't know what ground function it has, maybe it can be used.

Best detector for red soil is ... red detector!

My guess is that a VLF machine with manual ground balancing will also work on red soilAsk the masters to give your suggestions.

You need a pulse detector with selection and dd coil and ground balance something I almost finished...

Dear Master, can you give me more guidance?

I now have the easiest choice, polones in Indonesia, which is said to have ground balance, I'm not sure if it's true.

It's not clear enough. It also has a 4046vco board.
