Rule Industries 33ALA High Water Bilge Alarm Kit with Float Switch and In-Dash Gauge 12V

The Rule Industries 33ALA High Water Bilge Alarm is a complete 12-volt DC monitoring system designed to alert boaters to rising bilge water levels before they become a serious problem. The kit includes a mercury-free Rule-A-Matic Plus float switch and a compact in-dash gauge that delivers both a visual LED indicator and a loud 85 dB audible alarm, ensuring you receive a clear warning even in noisy onboard environments.

Designed for continuous, unattended monitoring, this system is ideal for larger yachts, commercial vessels, and any boat with compartments that aren't under constant observation. The float switch activates the alarm when water levels rise, providing an early warning that allows time to respond before damage occurs. For vessels with multiple compartments, additional Rule float switches can be added to the system to expand coverage.
