1. Sonar Fundamentals
1.1 Traditional 2D Sonar
Traditional 2D sonar, often referred to as “down-looking” sonar, emits sound pulses in a cone beneath the boat. The returns provide information about depth, fish arches, and bottom structure, displayed as colored shapes on the monitor. Key attributes include:
- Beam Angle: Typically 20°–60° cone
- Data Rate: Between 15–60 pings per second
- Display: Continuous real-time scrolling “waterfall” of returns
- Applications: Effective for general depth estimation and identifying schooling fish.
1.2 Side-Imaging Sonar
Side imaging sonar casts fan-shaped beams to both sides of the boat, revealing structures and fish that aren’t immediately beneath it. Key characteristics include:
- Beam Width: 60°–120° on both sides
- Data Rate: 400–1,000 scans per second
- Display: Horizontal “slices” illustrating structures up to 100+ ft away
- Applications: Particularly useful for locating underwater brush piles, rock bars, and shorelines.
1.3 Garmin LiveScope
Garmin LiveScope utilizes thousands of narrow, high-frequency sound pulses per second to create a real-time video feed of the underwater environment. The modes include:
- Forward-Facing: Scans 30° wide ahead of the boat, up to 200 ft
- Down-Scanning: Scans 30° wide below the boat, reaching depths of 125 ft
- Side-Scanning (LiveScope Plus): Provides 70° scans on each side, up to 200 ft
