Bait boat sonar technology transforms a simple delivery tool into a lake intelligence system. Understanding how 125kHz sonar works helps you get maximum value from fish finder bait boats like the LYX-001C and 001D. This guide explains the technology and how to interpret what you see on the display.

How Sonar Works on a Bait Boat

The sonar transducer mounted under the hull sends sound waves downward. When the wave hits the lake bottom or a fish, it bounces back. The time delay is converted to depth reading on your remote controller screen. On LYX-001C and 001D, the fish alarm beeps when it detects a fish-sized object within range. This helps you choose where to drop bait — drop it where fish are active, not in empty water.

Sonar vs Fish Finder: What's the Difference?

"Fish finder" and "sonar" are often used interchangeably. Technically, "sonar" is the technology; "fish finder" is the product category. On RC bait boats, the key question is: does the boat show depth only, or does it also show fish alarms? The LYX-001C and 001D show both depth AND fish alarm on the remote screen.

Frequently Asked Questions

How deep can the sonar fish finder detect?

Our sonar fish finder can detect water depth up to 30 meters and fish at depths up to 25 meters. The detection range covers a 90-degree cone beneath the boat, scanning approximately 40-50 square meters of water.

Can the sonar detect fish size?

The sonar displays fish icons on the LCD screen with size indicators. Small, medium, and large fish are shown differently. While it cannot measure exact fish weight, the size classification helps anglers target larger fish.

Does the sonar work in murky water?

Yes, sonar technology uses sound waves rather than light, so it works effectively in murky, muddy, or dark water conditions. This is one of the key advantages of sonar over visual fish detection methods.
