Stud and metal detector that works

[asalcedo]

I have tried three multi material (stud, metal and electric wiring

detectors. Each a bit more expensive than the previous one.

The latest one is the Zircon Pro SL

has proven very reliable.

Would anybody know if this Bosch one is good?

depends what you are trying to scan through. Anything foil backed or covered will usually prevent them working.
