The FREEDOM8 Shark Deterrent from SOS (Sentinel Ocean Systems) is an advanced personal electronic shark deterrent designed for all ocean users, including divers, snorkelers, spearfishers, surfers, swimmers, and ocean adventurers. When activated, the deterrent creates a powerful electric field around the user that produces an aversive response in an approaching shark, encouraging sharks to turn away before making contact.
The technology behind FREEDOM8 has been developed and refined over more than two decades.

The FREEDOM8 Shark Deterrent has been independently evaluated by leading shark researchers and universities, with results published in multiple peer-reviewed scientific journals. Testing across several shark species has demonstrated a measurable reduction in close-range interactions and bite probability when the technology is active.

FREEDOM8 gives people in ocean waters an additional level of personal protection that travels with them. It is designed to reduce the risk of shark interaction; however, no shark deterrent can eliminate risk, and responsible ocean-safety practices should always be followed.
