🔍 Key Concepts

• How an echo sounder works (sound pulse down, echo back) • The difference between draft, keel, and waterline • What the instrument actually measures: time to hard return vs. any averaging

💭 Think About

• Does an echo sounder know where your keel or waterline is, or does it only know the time for the sound to go down and back? • Is the returning signal based on the first solid reflection (hard bottom/obstruction) or can it detect a soft, gradual layer like mud separately? • Is the depth shown on the display an instantaneous point measurement or some kind of average over a vertical distance?

✅ Before You Answer

• Verify whether the transducer is located at/near the hull and what that implies about what is actually measured • Consider if the equipment can automatically account for keel clearance unless a correction is manually entered • Think about whether the physics of sound reflection allows it to distinguish or average between soft vs hard bottom without special processing
