The BKK Heavy Circle Glow is developed specifically for low light conditions, namely for night fishing or deep dark waters.
The BKK M-series glow paint on the hook adds attractiveness and visibility to the hook, triggering the fish to bite.
In addition to the effective circle hook design, the offset hook point (reversed) further enhances the hook up rate.
When fishing very deep under the surface, the exposed hook point helps to maximize the chances of fish's self-hookups.
