FREEDOM8 is for professional adventurers and is scientifically tested and designed to reduce the risk of shark interaction. FREEDOM8 products have been independently evaluated to effectively turn sharks away by the world’s leading scientific experts on sharks. Independent research and testing by universities has resulted in a number of peer reviewed science journals confirming the effectiveness of the technology.
 
The technology and patents have a twenty-year development history, in partnership with organisations such as the world’s leading experts in White Sharks, the KwaZulu-Natal Sharks Board in South Africa. As a result, FREEDOM8 is trusted by professional adventurers around the world and used by professional divers and marine personnel in various industries.

Freedom8 Electrical Shark Deterrent system
The Science behind the Freedom8 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.
 
A Purpose‑Built Electrical Field That Disrupts Shark Approach Behavior
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.
 
What Happens Underwater
The Freedom8 emits a precisely tuned electrical pulse optimised for shark sensory disruption.
The pulse forms a protective zone around the diver, typically extending several meters.
As a shark approaches, the field interferes with its electroreception, triggering a clear avoidance response.
The deterrent effect is behavioural, not injurious – the shark is not harmed, only repelled.
 
Proven, Field-Tested Technology
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.
 
Built for Demanding Dive Environments
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.
