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 behavioral, 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.

- Streamlined deployment and charging
- Designed to complement existing dive gear
