Well, 30X30cm @ 3 meter is impossible, even in air.

You may get 2 meters depth with 50-150cm coil diameter.

Magnetometer is not very good for brass or noble metals.

If the soil is just very weak mineralized a Pulse Induction
with 1m frame may work, if heavy mineralized you should
go for the Jeohunter 3D and using the super big 1m coil.

This machine has really very good ground elimination
and can see through heavy mineralized soil or stones.
But you need some experience first and the soil must
have a minimum of the identical mineralisation level!
