Sentinel Ocean Systems - SOS

For more than ten years, Sentinel Ocean Systems has been driven by a single purpose: creating the most reliable and innovative marine safety equipment on the water.

What began as a focused engineering and manufacturing project quickly grew into a company committed to redefining what marine safety can be. Our work is shaped by real‑world experience, proven scientific principles, and the latest advances in engineering and production.

Supported by a global community of marine enthusiasts, our team brings together deep technical expertise and a genuine passion for the ocean. This combination allows us to design and build safety devices that people can trust when it matters most.

At Sentinel Ocean Systems, we believe everyone should be able to enjoy the ocean with confidence – and with respect for the wildlife and natural environments that make it so extraordinary.

Underwater Australasia is an official supplier of Sentinel Ocean Systems products with full waranty support. We have ove a decade of experience with Shark Shield, Ocean Guardian and other shark deterrent products. You can email our call our experienced team with any questions.
