Overview

The Impulse AQ Limited is built for experienced beach and shallow water hunters chasing deep gold jewelry. Pulse induction ignores salt water and black sand that make VLF machines chatter.

Adjustable pulse delay (7 to 11.5 microseconds) tunes sensitivity to small gold, iron and ground reject controls help in trashy sand, and a Volcanic Sand mode handles the most difficult beaches. The 12.5" mono coil is waterproof and the housing is rated to 3 ft.
