Dock Lifeguard manufactures stray electricity detection systems designed to alert users to dangerous AC and DC voltage in and around boat docks and marinas.
Dock Lifeguard is dedicated to water safety, specializing in advanced stray electricity detection systems for boat docks and marinas. Founded in 2012 by engineers responding to tragic electrocutions, the company provides critical early warning systems that monitor for hazardous AC and DC voltage in the water and on dock frames.
Their systems feature visual LED displays to indicate voltage levels and high-decibel audible alarms with warning strobes to alert swimmers and dock users of immediate danger. Dock Lifeguard systems offer added safety integration, such as signaling to trip GFCI breakers, and are an essential tool for preventing Electric Shock Drowning (ESD) in fresh water environments.

Common questions about manuals, registration, and support for this brand.
It continuously monitors the water and dock frame for stray AC and DC electricity. If hazardous voltage is detected, it triggers a visual strobe and audible siren to warn users.
No, the system cannot stop or prevent electricity from entering the water; it is strictly a detection and warning system designed to alert users so they can evacuate the area safely.
It should be placed 2 to 3 feet below the water surface, ideally closer to swimming areas or ladders. Avoid placing it near metal underwater structures or parallel to other electrical wires.
You should perform a system test monthly using the built-in Test button and wipe the probe clean of algae annually to ensure consistent detection range.
