Fisher Impulse AQ Metal Detector

Fisher Impulse AQ Metal Detector – Ultimate Beach & Gold Detection Performance

The Fisher Impulse AQ Metal Detector is a breakthrough in pulse induction technology and a top choice for serious beach hunters. Engineered for extreme sensitivity, especially to gold, this detector excels in wet sand, dry sand, black sand, and shallow surf—places where traditional VLF detectors struggle.

Built with Fisher’s advanced Pulse Induction (PI) system and featuring Zero Target Separation (ZTS®) and Highly Reactive System (HRS®) technologies, the Impulse AQ delivers exceptional target recognition. Its variable reactivity and precise iron rejection help reduce false signals, allowing you to focus on valuable targets like gold jewelry and deep coins.

Lightweight, ergonomic, and adjustable, the Impulse AQ provides comfort during long treasure-hunting sessions. With customizable sensitivity, threshold, frequency offset, and pulse delay, you can fine-tune performance for any beach environment.
