Re: powerfull pi detector

If there was a Quote "BEST", Everyone would have one.

Every detector has it good and bad points.

What size and types of metals are you trying to detect and at what distance.

Re: powerfull pi detector

5 Meters is Pretty Deep. I doubt you will find a detector for that.
And its even more difficult of a problem if you expect to Discriminate at that depth.

Sorry...........Gary
