Using multiple coils in close proximity, problem?

Correct, they will "talk" to each other and all you'll have is a mass of noise.

yea, but if I turn the firs coil on, get reading then turn off, move to the next coil and so on.

This way no two coils will be on at the same time

Sounds like a way to synchronise them

It's way easier to just synchronize them. Some detectors can be synchronized rather easily, I've seen 3 MXT's sync'd for about the same purpose as what you want. Also, doing sequential operation will either cost you depth (if you switch very quickly) or coverage (if you switch slowly).
