The Tuna Magnet Gravity Fishing is an advanced underwater acoustic system developed for serious offshore anglers. Inspired by acoustic patterns associated with baitfish schools, it turns the boat hull into a low-frequency vibration emitter designed to complement chunking and trolling techniques. Its marine-grade ASA housing is IP68 saltwater rated for long-lasting durability in demanding offshore environments. Featuring a 316L stainless steel mounting ring and heavy-duty tinned copper cables, it connects directly to the vessel's 12V power supply. Built on established marine bioacoustics principles, Tuna Magnet provides an additional advantage by promoting pelagic activity around your fishing area while maintaining reliable marine-grade performance.
Recommended use: offshore tuna, marlin and pelagic fishing during chunking and trolling operations.
The Tuna Magnet Gravity Fishing applies marine bioacoustics principles to generate low-frequency underwater vibrations designed for offshore fishing environments. Developed to complement chunking and trolling techniques, it produces modulated acoustic pulse sequences inspired by baitfish school behavior.
Reliable, durable and purpose-built for demanding offshore conditions, Tuna Magnet provides serious anglers with an additional technological advantage when targeting pelagic species.
The Gravity Tuna Magnet is an innovative acoustic system designed to attract tuna and other pelagic species through the emission of sound pulses. Available in either the In-Hull + Overboard version (hull-mounted and submerged) or the Water Only version (submerged use only), it adapts to various boat configurations and offshore sportfishing techniques.

The ASA housing is designed to withstand UV exposure, salt and harsh offshore conditions.

Tinned multi-conductor copper wiring reduces oxidation and ensures reliable power delivery.

Every component is selected to withstand the most demanding marine environments.

The system emits low-frequency pulses designed for offshore sportfishing applications.

Mounted inside the hull, the Tuna Magnet transmits its pulses through fiberglass into open water.

Direct battery connection provides simple integration aboard sportfishing boats.
How does Tuna Magnet Gravity Fishing work?
The system generates low-frequency underwater acoustic vibrations inspired by marine bioacoustics principles to complement offshore fishing techniques.
What installation method is recommended?
In-hull mounting is recommended for maximum acoustic transfer, although direct water deployment is also possible.
Is it suitable for saltwater use?
Yes. The IP68-rated ASA housing and marine-grade components are designed for harsh saltwater environments.
