Airflo's Sixth Sense Stillwater Sinking is a high-performance sink line designed for reservoir fishing. With its four sink speeds - S3 (7.6 cm/s), S5 (12.7 cm/s), S7 (17.8 cm/s) and S8 (20.3 cm/s) - it allows you to target precisely the right layer of water according to fish activity. Its polyurethane (PU) coating and Total Density Compensating (TDC) Ridge technology ensure a smooth descent and excellent line control. The Power Core provides optimum transmission of feel and bite, even at long distances. Its suppleness, lack of memory and profile designed for vertical prospecting make it an indispensable ally for technical reservoir anglers. 100% PVC-free, it combines performance with respect for the environment.
