Questions

Trusted by experienced divers and several naval organizations worldwide, the FREEDOM8 is
designed to enhance personal safety in the water, allowing you to focus on free‑diving,
spearfishing, scuba exploration, or kayak fishing while contributing to shark conservation
efforts.

With the FREEDOM8 by Sentinel Ocean Systems, you can head into the ocean with far
greater confidence. It is the only electronic shark‑deterrent system backed by independent
scientific validation, created specifically to reduce the risk of close encounters during your
underwater activities. More than two decades of research and rigorous testing have shaped
this technology, making it the preferred safety tool for numerous professional divers.

How the Freedom8 Works
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 optimized 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
SOS technology 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.
