FREEDOM 8 is designed for all ocean users and is built on over twenty years of shark deterrent technology development. Using a patented electrical deterrent system, FREEDOM 8 is designed to significantly reduce the likelihood of a shark interaction without harming any marine animals.
The underlying technology has been independently evaluated in multiple scientific studies and has been the subject of peer-reviewed research conducted by leading universities and shark scientists. These studies have demonstrated that electrical shark deterrents can significantly alter shark behaviour and reduce the likelihood of close-range interactions.
Developed in collaboration with some of the world’s leading shark researchers, including the KwaZulu-Natal Sharks Board in South Africa, the technology has evolved through decades of research, testing and real-world use. Today, FREEDOM 8 is trusted by scuba divers, spearing enthusiasts, snorkelers, freedivers, swimmers, ocean professionals and marine personnel who rely on proven, non-lethal shark deterrent technology in demanding environments.

Sharks have evolved over 450 million years to detect the faint electromagnetic fields produced by living things. We use this sensitivity against them.
Enter the Water
Once turned on the Freedom 8 activates automatically when the electrodes contact the water. No delay — instant protection from the moment you enter.
Protective Field Forms
A three-dimensional electromagnetic field radiates from the electrode tips, creating an invisible protective zone around you.
Sharks Detect & Retreat
Sharks have highly sensitive electroreceptors called Ampullae of Lorenzini. The Freedom8 overwhelms these receptors, causing an instinctive retreat response.
The Science behind the Freedom 8 Electrical Shark Deterrent system is built on a well‑established principle in shark biology: sharks depend on their ampullae of Lorenzini – highly sensitive electroreceptors – to interpret the tiny electrical signals emitted by living prey. These receptors are incredibly effective at close‑range detection, but they’re also extremely vulnerable to strong, irregular electrical fields.
The Freedom8 generates a powerful, low‑frequency electrical field between two electrodes. This field extends in a three‑dimensional radius around the diver. When a shark enters the field, the signal overwhelms its electroreceptors, creating a strong but harmless aversive sensation. The shark’s natural response is to veer away.
For divers, this means a significant reduction in the likelihood of a close‑range encounter, without affecting normal marine life or the surrounding environment.
Technology used by the Freedom8 has been validated through independent testing, controlled field trials, and extensive real‑world use by professional divers, spearfishers, and commercial operators. Across thousands of hours in the water, the system has consistently demonstrated its ability to discourage unwanted shark interactions.
The Freedom8 is engineered for reliability and ease of integration into professional dive workflows. Whether you’re guiding clients, running a shop, or diving remote sites, the system provides an added layer of confidence without complicating your setup.
