Freedom 8 Shark Deterrent
The world's most advanced personal shark deterrent. The Freedom 8 is a wearable shark deterrent built on over 20 years of proven technology. It creates a powerful electrical field that is scientifically demonstrated to significantly reduce the likelihood of a shark interaction — without harming any marine life.
Trusted by scuba divers, spearfishers, freedivers, snorkelers, swimmers, and ocean professionals worldwide, the Freedom 8 gives you real confidence in the water backed by peer-reviewed science and independent testing.
Why Freedom 8?
Proven Technology
Independently evaluated in multiple scientific studies and peer-reviewed research by leading universities and shark scientists.
Non-Lethal
Discourages close-range shark interactions without injuring sharks or affecting other marine animals.
Real-World Tested
Developed with the KwaZulu-Natal Sharks Board and validated across thousands of hours of real diving and spearfishing use.
Built for Reliability
Enhanced housing, sealing, and durability built for demanding ocean conditions and daily professional use.
How It Works
Sharks have evolved over 450 million years to detect the faint electromagnetic fields produced by living things through specialized electroreceptors called the Ampullae of Lorenzini. These receptors are highly sensitive — and highly vulnerable to strong, irregular electrical fields.
The Freedom 8 generates a powerful, low-frequency electrical field between two electrodes, radiating a three-dimensional protective zone around you. When a shark enters the field, the signal overwhelms its electroreceptors, triggering an instinctive avoidance response. The shark is repelled, not harmed.
Features
