1. Assemble cobra vibration ring on fishing rod, usually connected to fishing line.

2. Straighten the line on the vibrating ring reel, then gently shake the fishing rod to loosen the fishing line and make the vibrating ring vibrate.

4. After the fish is hooked, grab the fishing line by hand, slowly lift the fishing rod and lift the fish to the surface.
