The Flutter Tube embodies the optimal solution for bottom fishing for black sea bream. It is designed to achieve both reliable holding performance under action-induced stress and effective hooking capabilities. In black sea bream fishing, hotspots are not limited to flat areas but also include structures such as oyster beds and rocky terrain, requiring delicate approaches to avoid snagging. The material is a non-salt, semi-hard type with added flavor and scent to prevent worm displacement during strong bottom bumps or bites occurring when a snag is freed. Despite the slightly firmer material, the hollow structure allows the worm to easily compress during a black sea bream's bite, facilitating hook exposure. Additionally, the hollow body enhances lifelike movements, enabling each part to sway and drift underwater naturally. The parts respond to variations in water flow intensity, accommodating a wide range of fishing techniques from retrieval fishing to slow bottom fishing. The Flutter Tube, which meets the fundamental requirements of black sea bream fishing at a high level, helps anglers inch closer to their next catch.
