Choose Your Setup
Both versions run the same acoustic technology — the difference is how you mount and deploy. Hull mounting delivers the strongest signal transfer for serious offshore anglers.

Published research has demonstrated that many marine species can detect and respond to low-frequency acoustic stimuli. Tuna Magnet applies these principles in a practical offshore fishing system.
Marine species can detect and respond to low-frequency acoustic stimuli in open-water environments.
Tuna Magnet generates low-frequency vibrations shaped by decades of marine bioacoustics research — applied signal design for serious offshore anglers, not guesswork.
Marine bioacoustics research demonstrates that marine species respond to specific low-frequency acoustic signals — particularly in open-water environments where visual cues fade.
Tuna Magnet generates low-frequency acoustic vibrations inspired by that research — modulated pulse sequences engineered for hull-coupled transmission offshore.
The science established the principle. Tuna Magnet delivers it with marine-grade hardware — carrying forward the legacy Tuna Teaser concept for today's serious anglers.
Inspired by published marine bioacoustics research and the legacy Tuna Teaser concept — refined for modern hull-coupled deployment.

Replace placeholders with your product photography when ready.
Sound transmits through the hull into open water — your boat becomes the underwater emitter.
Many anglers report the strongest results while chunking for tuna in open water.
Field-tested acoustic technology designed for chunk fishing and trolling in demanding pelagic conditions.

Get the DealTwo Ways To Deploy
Hull mounting delivers the strongest acoustic coupling. Drop-in deployment is available when you need a faster setup on the water.
Mount inside the hull below the waterline. Vibrations transfer through the fiberglass into open water — your boat becomes the acoustic emitter.
Deploy directly in the water beside the hull when in-hull mounting is not practical. Effective offshore, with hull mounting delivering superior acoustic transfer.
