Fisher Impulse AQ Limited Metal Detector by Fisher
The Fisher Impulse AQ Limited is a high-quality pulse induction metal detector made just for advanced beach, surf, and shallow water hunting. This machine is made for experienced users who want to find deep gold and artifacts in tough saltwater or volcanic sand environments. It stands out because it has Pulse Induction technology and great target separation capabilities.
The Impulse AQ is built to work where other detectors fail, including in damp salt and dark sand. It has a pulse delay that can be changed (7–11.5 μs) and multitone audio that makes it very sensitive to objects with poor conductivity, such as tiny gold.
Advanced features include controls for rejecting iron and ground, many working modes (All Metal, Tone, Mute, and Volcanic Sand), and a waterproof 12.5" mono searchcoil that can find things deep below. The customizable settings for ATS, Delay, and Reject let you fine-tune your performance to get the best results in your individual hunting field.
The Impulse AQ is built to last in tough beach conditions. It has a strong body, sealed circuitry, and a waterproof case that can handle water up to 3 feet deep. The adjustable shaft and balanced 4.2 lb frame make it comfortable to use for long periods of time. The rechargeable NiMH battery lasts up to 3.5 hours. It comes with easy-to-use controls and a watertight system that has been tested by the manufacturer, so you can start finding treasure right away.
Purpose
Beach Hunting, Shallow Water Treasure Hunting, Gold Jewelry Detection, Wet Sand Searching. The entire unit is waterproof up to 3 feet, not just the battery compartment.
Why Choose Fisher Impulse AQ Limited?
The Fisher Impulse AQ is specifically designed for serious beach hunters looking for maximum depth and performance in saltwater, wet sand, and mineralized beach conditions. If you primarily detect in parks, relic sites, or highly trashy inland areas, this may not be the ideal unit for you.
Here’s what you get with the Impulse AQ:
- Pulse Induction (PI) Technology – Excels in saltwater and black sand, ignoring mineralization that would cripple VLF detectors.
- Superior Gold Detection – Optimized for low-conductivity targets like gold jewelry while still detecting high-conductive metals.
- Waterproof Construction – Fully submersible up to 3 feet (1 meter) for shallow-water detecting.
- 12.5” Mono Searchcoil – Provides deep penetration and broad coverage on wet and dry sand.
- Adjustable Pulse Delay (7μs - 11.5μs) – Allows tuning for small gold pieces or larger, deeper targets.
- Tone, Mute, and Volcanic Sand Modes – Provides flexibility for different beach conditions and target preferences.
- Weight: 4.2 lbs – Lightweight for extended hunting sessions.
