🔍 Key Concepts

• How most small-boat electronic depth sounders (fish finders) actually measure depth • The role of time and speed through water in determining distance • Differences between sound, radio, and radar signals in water

💭 Think About

• Ask yourself: does the depth finder measure depth directly, or does it measure time and then convert that to depth? • Which type of wave (sound, radio, radar, pressure) is most practical and commonly used for sending a signal down to the bottom and receiving an echo back in water? • Think about which of these phenomena is reliably predictable in seawater so that electronics can compute depth from it.

✅ Before You Answer

• Identify which option involves a signal going down to the bottom and reflecting back from it • Confirm which signal type is known to travel at a nearly constant speed in water and is widely used in sonar equipment • Eliminate any options that describe methods not typically used by recreational or commercial depth sounders (e.g., pure pressure-based gauges vs. echo-based electronics)
