Have you ever wondered how commercial fishermen navigate the Great Lakes when visibility isn’t perfect?
One important piece of equipment aboard many commercial fishing vessels is marine radar! 📡
Radar works by sending out radio waves that bounce off objects and return to the vessel’s radar system. This helps fishermen identify what’s around them, even when it’s difficult to see with the naked eye.
🌊 Here’s what radar helps our fishermen do:
📡 Detect other vessels: Radar can help crews identify boats and ships in the surrounding waters.
🌫️ Navigate in reduced visibility: Fog, rain, and darkness can make it difficult to see what’s ahead. Radar provides another important source of information.
⚓ Identify obstacles: Depending on conditions and equipment, radar can help detect shorelines, buoys, and other objects above the water.
🐟 Improve situational awareness: Radar gives fishermen another tool to help make informed decisions while working on the lake.
Did you know? Radar doesn’t show fish swimming underwater! That’s a different technology called sonar, which uses sound waves rather than radio waves.
While radar is an incredibly useful tool, it doesn’t replace experience, careful navigation, or keeping a proper lookout.
