Fisher Impulse AQ Metal Detector
The Fisher Impulse AQ is a professional-grade Pulse Induction metal detector purpose-built for serious beach, surf, wet sand, black sand, and shallow-water hunting. Designed for experienced detectorists searching for deep gold jewelry and relics in difficult saltwater environments, the Impulse AQ combines adjustable pulse delay, multitone audio, iron and ground rejection controls, and specialized beach-focused operating modes to perform where many standard VLF detectors struggle.
What’s Included
Built for Saltwater and Black Sand
The Impulse AQ is designed for challenging beach environments where saltwater, wet sand, and black sand can make many detectors unstable. Its Pulse Induction platform helps ignore mineralization that commonly affects VLF detectors, making it a strong choice for serious beach hunters.
Adjustable Pulse Delay
The adjustable pulse delay range of 7–11.5 μs lets experienced users tune the detector for small gold sensitivity or larger, deeper targets. This level of control is especially useful when hunting beaches with changing sand, mineralization, and target conditions.
Four Operating Modes
The Impulse AQ gives you four specialized operating modes: All Metal, Tone, Mute, and Volcanic Sand. These modes help you adapt to different beach conditions, from maximum depth searching to difficult volcanic or mineralized sand.
Iron and Ground Rejection Controls
Adjustable iron rejection and manual ground balance give advanced users more control over how the detector responds to unwanted iron and mineralized ground. These settings help fine-tune the detector for serious wet sand and shallow-water target recovery.
Waterproof to 3 ft / 1 m
The Impulse AQ is waterproof to 3 ft / 1 m for shallow-water detecting, surf edges, wet sand, and harsh beach conditions. It is built for beach recovery work where salt, spray, and shallow water are part of the hunt.
Professional Analog Control Layout
Instead of a digital screen, the Impulse AQ uses an analog control layout with knobs for expert-level adjustments. Controls such as ATS, Delay, Reject, Sensitivity, Volume, and ground balance allow experienced users to tune the detector to the site.
Why Choose the Fisher Impulse AQ?
Beach-Focused PI Technology
Pulse Induction performance is ideal for wet salt sand, black sand, surf, and shallow-water environments.
Gold Jewelry Sensitivity
Tuned for low-conductivity targets such as gold jewelry while still detecting high-conductive metals.
12.5" Mono Searchcoil
The large mono coil provides broad coverage and strong depth on wet and dry sand.
Multitone Audio
Multitone audio feedback helps separate target responses by sound while hunting.
Volcanic Sand Mode
Specialized mode helps the detector perform in difficult volcanic sand and highly mineralized beach conditions.
Manual Ground Balance
Adjustable ground balance gives experienced users more control in changing beach conditions.
Waterproof Housing
Fully waterproof to 3 ft / 1 m for surf, shallow-water, wet sand, and harsh beach use.
Expert-Level Tuning
ATS, Delay, Reject, Sensitivity, and Volume controls allow detailed adjustment for site conditions.
Rechargeable Battery
Rechargeable NiMH 2200 mAh battery provides approximately 3.5 hours of detecting time.
