Using a compact float switch and dash mounted alarm, Rule provides boaters with a warning to high bilge water levels. Ideal for larger yachts and commercial vessels larger than 26' with unmanned compartments that have to comply with CFR 182.530. A bright LED indicator light provides a visual alarm when ambient noise levels exceed alarm volume. Constantly monitor your bilge for water and stay compliant to Coast Guard regulations with a Hi-Water Bilge Alarm from Rule.
