Many people who fish sinking flies using a marker (bobber) have experienced the marker twitching, indicating a bite, but failing to hook the fish. The biggest advantage of this submerged float system is that it floats just at the surface, almost regardless of the fly's weight. With conventional markers, if the fish feels any resistance or unnatural sensation, it will spit out the fly. This submerged float allows the fish to bite without any resistance, pulling the float under. The indication of a bite is clear, and hooking misses are dramatically reduced. This system is especially effective in pond-type managed fishing areas. 【Catch Report】 December 18, 2025 Large-scale stocking pond-type managed fishing area Weather: Sunny Temperature: 5-13°C Water Temperature: 10°C Using conventional markers, the fish were wary, and the hooking rate was a poor 20-50%. Catching even 10 fish would be considered satisfactory. However, on this day, the hooking rate was an astonishing 80%, resulting in a large catch of 29 large fish, a great haul for this pond. 【Important Notes】 The submerged float is made of expanded polystyrene, so it has strong buoyancy but is fragile. Do not pull on it forcefully or crush it. Fly Fishing Marker Submerged Float
