MarineGuard Network is a subsidiary of Sure Action Inc., the only manufacturer to successfully develop the Pulsor stress sensor, a security device that mounts under flooring or boat decking to provide invisible, reliable, unparalleled security detection.

In 1990, the MarineGuard product line was developed to fill a need in the marine industry.   As boat theft increased worldwide, reliable security devices, that could withstand the harsh marine environment and not be falsely activated by a boat's movement on the water or against a dock, were not available on the market.   Austin and Trent Stack recognized that the Pulsor could be adapted to withstand marine conditions and were ideal for the boating application.

In 1991, Sure Action introduced its MarineGuard product.  In 2007, MarineGuard just introduced its 5th generation of MarineGuard security products.  All MarineGuard control panels are coated with a weather protector and all Deck Sensors (marine version of the Pulsor) are sealed and use marine-grade wire.

In a world where products are designed to have a short shelf-life, Sure Action and MarineGuard products continue to be designed with longevity in mind.  Our MarineGuard products are epoxied or coated with a weather-proofing sealant to protect components from sunlight, wind, rain, saltwater and more.
