How to Set Up a Raymarine Dragonfly Fishfinder

All Raymarine fishfinders operate using Sonar.
A sound wave is produced by a transducer connected to a fishfinder and is sent through the water. At the transducer the wave is narrow, however as it penetrates deeper, the sound wave spreads forming a cone shaped beam. When the sound wave encounters something within this beam, it bounces back to the transducer. By measuring the very small amount of time between when the sound wave was sent out and when it bounces back your fishfinder calculates the distance of the object below the boat.
If the signal doesn’t encounter anything along the way, it reaches the bottom. Soft bottoms like mud and weeds tend to absorb the signal. Hard bottoms such as rock reflect a stronger signal back.
