One fog horn blast each 2 minutes?

A fog horn blast every two minutes serves as an essential navigational aid for vessels in low-visibility conditions, such as fog or heavy rain. This regular interval allows mariners to gauge their distance from the source of the sound and navigate safely. The consistent sound helps to prevent collisions and ensures that boats can maintain awareness of their surroundings despite poor visibility. The use of fog horns is a crucial safety measure in maritime operations.
