Description
On a saltwater beach, a pulse-induction coil ignores the salt that stops other detectors cold. This 8 inch open pulse-induction coil is built for the Fisher Impulse AQ: wider coverage and clean depth in wet sand, surf and volcanic black-sand ground that overwhelms VLF machines.
At a glance: This is the genuine Fisher 8 in / 20 cm open-frame pulse-induction search coil for the Impulse AQ, supplied with the mounting tube and coil hardware. Pulse induction ignores the salt and mineralization that stop VLF detectors, so on wet sand, surf zones and volcanic black sand this coil delivers wide coverage and clean depth on the Impulse AQ.

Why the 8 in open-frame pulse induction coil
Saltwater and black sand are where most detectors fail: the ground itself signals, drowning the targets. The Fisher Impulse AQ is a pulse-induction machine built to ignore that, and this 8 inch open coil is matched to it. The open-frame design keeps a larger coil light and easy to sweep through wet sand and surf, and pulse induction gives it clean depth on rings, coins and other targets in ground that overwhelms a VLF detector. Supplied with the mounting tube and coil hardware, it is the coverage coil for the Impulse AQ on the beach. Because it is a pulse-induction coil on the Impulse AQ's own connector, it fits the Impulse AQ only.

History Seekers is a small American business and an authorized First Texas dealer (Fisher, Teknetics and Bounty Hunter are one El Paso company). Everyone here detects, top down, for coins, relics, jewelry and gold, and prior field experience is a hiring requirement, not a coincidence. The person who answers your fitment question may be the one who packs the coil and drives it to the UPS drop. The story is more important than the artifact.
