章 146: Chapter 137: Encounter with a Shark, Where is My Rolling Pin, Zhang Wei?

Chu Mingcheng armed his speargun, pulling back the rubber band to load it.

Zhang Wei said the fish finder detected fish, which meant he had been too preoccupied thinking about catching prawns earlier to notice.

The fish finder works by reflecting electromagnetic waves; the closer the fishing line to shallow water, the stronger the reflection.

The larger the fish, the clearer its display on the screen.

Larger targets appear darker and thicker in color, while smaller ones naturally appear lighter.

However, the length displayed on the screen doesn't directly correlate to the size of the fish; it merely indicates the duration of the fish's presence within the detection range.

At a depth of fourteen meters, he saw a group of Deep Sea Red Friend and Red Snappers being active in the area.
