“Blue Light, Set of 4” A-Shape (Straight Type) This is a constant-on blue light model that uses the A-shape (straight) design. Blue light (approximately 450-490nm) has very high transparency in water. While red, green, and yellow light attenuate within a few meters, blue is known as the only visible light wavelength that reaches deeper and further. The sea appears blue because only this wavelength travels long distances underwater. Due to this characteristic, the blue light is particularly effective in: ・Clear water ・Deep water ・Points with fast currents ・Situations where migratory fish move quickly The single-color blue light has strong directivity, forming a "streak of light" around the rig, and has the effect of gently attracting targets with phototaxis, such as horse mackerel, mackerel, barracuda, hairtail, and squid, from a certain distance. This product is equipped with a high-efficiency LED and is adjusted to a delicate brightness setting that is neither too dim nor too bright. The stable light of constant illumination creates a "calm attraction" different from flashing, and is characterized by its very high effectiveness in: ・Fish with strong wariness ・When activity is low ・At the boundary between light and shadow of a night light The weight is approximately 2.5g, making it ultra-lightweight. It has versatility that makes it easy to incorporate into a wide range of rigs, such as sabiki, bottom fishing, float rigs, casting sabiki, small boat fishing, and hairtail tenya. The light weight also makes it less likely to be affected by currents and does not impair the natural movement of the rig, which is a significant advantage. The precision resin body and O-ring sealed structure provide very high waterproof and pressure resistance, continuing to emit stable light even in deep water, rapid descent points, and situations where sea conditions deteriorate. Blue light is less likely to scatter even in rough sea conditions and maintains a focused light axis, demonstrating a strong presence on the migratory lines of mackerel, barracuda, and hairtail. It employs an auto-light mechanism that automatically turns on when a CR425 battery (sold separately) is inserted, contributing to improved handling in the dark. No switch operation is required, making it smooth to re-deploy on boats and breakwaters. ■Specifications ・Shape: A-Shape (Straight) ・Type: Blue Light (Constant Blue Light) ・Total Length: Approximately 89mm / Diameter: Approximately 9.5mm ・Weight: Approximately 2.5g ・Battery: CR425 (sold separately) ・Waterproof: O-ring sealed structure ・Uses: Sabiki / Bottom Fishing / Ajing / Barracuda / Hairtail / Squid / Boat Fishing / Clear Water, Deep Water, Fast Current ⸻ ■Shipping Simple packaging in a transparent bag + envelope (for low-cost provision) ⸻ Other colors are available ↓↓↓↓ #LightweightFishingLightIzuOkappari
