DUO Spearhead Ryuki 50MDF is a compact medium deep diving trout minnow engineered for precise control in rivers and faster current conditions. Measuring 50 mm and weighing 3.4 g, this model extends the effective depth range of the Ryuki 50 series while maintaining the tight, responsive action the series is known for.
The lure operates at a running depth of approximately 0.6–1.0 m, making it ideal for probing deeper runs, drop-offs and stronger current seams where trout often hold. Its floating construction allows controlled rise during pauses, adding versatility when fishing upstream or around structure.
The 50MDF is equipped with DUO’s magnet-assisted weight transfer system. During the cast, the movable internal weight shifts to maximize casting distance and flight stability. Once the lure enters the water, the weight is held in position by a magnet, stabilizing the balance and ensuring consistent swimming performance even in rapid river currents.
The action initiates instantly upon retrieve and remains stable under aggressive rod input, allowing effective twitching and short-distance control. This makes the Ryuki 50MDF particularly effective in technical river environments where precision and depth control are critical.
