Fisher Pinpointers

The Fisher F-Pulse is one of the few pulse-induction pinpointers on the market, a design that stays stable in the mineralized ground, black sand, and salt water that make ordinary VLF pinpointers chatter. It's waterproof, runs on common AA batteries, and works with any metal detector brand, making it a rugged, cost-effective choice for serious recovery. Serious Detecting carries the F-Pulse from Fisher Research Labs.

The Fisher F-Pulse Pinpointer

The F-Pulse is Fisher Research Labs' waterproof pinpointer, and its standout feature is pulse-induction detection, which is rare in a pinpointer, where most use VLF. PI lets the F-Pulse hold a steady, quiet threshold in heavily mineralized soil, black sand, and salt water, exactly where other pointers false. It's waterproof to 6 feet, offers three sensitivity levels (high, medium, low) and proportional response that intensifies as you near the target, and gives you two alert modes: beep-and-vibrate or silent vibrate-only. Add a single-button interface, retune, an on/off LED flashlight, a lost-mode alarm, auto shutdown, and an abrasion-resistant housing built to outlast cheaper pointers. It runs on two AA batteries and works with any metal detector.

Who Is the F-Pulse For?

The F-Pulse is the pick for hunters who work tough ground. If you detect saltwater beaches, black sand, or heavily mineralized soil (the conditions that overwhelm VLF pinpointers), the pulse-induction F-Pulse stays stable where others won't. It's also a smart choice for anyone who wants a rugged, waterproof pointer on common AA batteries that pairs with any detector brand, at a cost-effective price. For dry, mild-ground park hunting, a standard VLF pinpointer is fine; the F-Pulse earns its place when the ground gets difficult.

Is the Fisher F-Pulse waterproof?

Yes, the Fisher F-Pulse is waterproof to 6 feet (1.8 m) for up to one hour, so it handles wet sand, shallow water, rain, and mud. That makes it a solid companion for beach and freshwater hunting; rinse it in fresh water after saltwater use and check the O-ring on the battery cap before each submersion. If you wade or dive deeper than 6 feet, compare the deeper-rated models in our full pinpointer range, and pair your F-Pulse with a sand scoop for beach recovery.

What makes a pulse-induction pinpointer like the Fisher F-Pulse different?

A pulse-induction pinpointer like the Fisher F-Pulse is different because it largely ignores ground mineralization, giving a steadier, quieter response in mineralized soil, black sand, and wet salt sand. Most pinpointers use VLF, which can false in those conditions and need constant retuning. It's the same reason PI is favored for saltwater and goldfield detecting; if you hunt those conditions, also browse our gold detectors and waterproof metal detectors.

Does the Fisher F-Pulse work with any metal detector?

Yes, the Fisher F-Pulse works with any metal detector, because it is a standalone pinpointer used alongside any brand or model rather than tied to a particular detector platform. It also has 16 frequency-shift positions, so you can shift it away from your detector to avoid interference while you dig. Pair it with any machine from our metal detector range, including Fisher detectors, and a good digger to complete your kit.
