Nokta Magnetar 9000

The Magnetar 9000 is Nokta's submersible pulse induction detector, built for the two places VLF machines fall apart: wet salt sand and heavily mineralized ground. Pulse induction ignores the mineralization that swamps other detectors, and being submersible means it works in the surf and below it rather than only up to the waterline. Discrimination is limited, as it is on any PI machine, so expect to dig more. What you get in return is depth where other detectors simply stop.
