We’ve provided several answers to questions related to Fisher Impulse-AQ Limited Pulse Induction Waterproof Metal Detector , see some other helpful Q&A related to this product.
Question: Who is the IMPULSE AQ best for?
Answer: The AQ is best suited for beach hunters who primarily target gold jewelry in saltwater surf and wet sand. It is less suited for land relic hunting or coin shooting.
Question: What coil comes with the Fisher Impulse AQ Limited metal detector?
Answer:
The Fisher Impulse-AQ Limited Pulse Induction Waterproof Metal Detector comes with an 8-inch round waterproof search coil as standard equipment. This coil provides excellent depth detection and is fully submersible, making it perfect for underwater detecting and beach hunting. The 8-inch coil offers a good balance between depth penetration and target separation, ideal for finding coins, jewelry, and relics in various terrains. As a pulse induction detector, the AQ works exceptionally well in saltwater and mineralized ground conditions.

Question: How long does the battery last?
Answer: The AQ’s rechargeable NiMH battery runs for about 3.5 hours per pack. Many users carry a spare pack to extend hunting time across tide cycles.
Question: How deep can it detect?
Answer: The AQ achieves exceptional depth in wet salt and black sand where traditional detectors struggle. Depth varies by target size and conditions, but it’s known for reaching gold jewelry beyond the range of many VLF detectors.
Question: Can it find small gold jewelry, like thin chains?
Answer: Yes. Thanks to its adjustable pulse delay, the AQ can be tuned to detect very small, low-conductive gold items that are often missed by other detectors.
Question: How well does the AQ handle saltwater beaches?
Answer: The AQ was purpose-built for saltwater environments. Unlike VLF/multi-frequency detectors that must “turn down” sensitivity to quiet the salt, the AQ keeps its depth and signal strength in surf, wet sand, and mineralized beach conditions.
Question: Why should I choose the IMPULSE AQ over other detectors for beach hunting?
Answer: Because it uses Pulse Induction (PI) technology, the AQ is stable in wet salt and black sand while maintaining sensitivity to small, low-conductive gold targets (like thin chains and small rings). Many other detectors lose performance in these conditions.
Question: What is the Fisher IMPULSE AQ designed for?
Answer: The IMPULSE AQ is a specialist detector built specifically for saltwater beach hunting and finding gold jewelry in the surf and wet sand. It’s not a general-purpose detector but excels in its niche.
