The PENN Spinfisher VII features IPX5 sealing so whether it gets hit with a wave, or you let it ride in the spray all the way home, you don't have to worry about saltwater getting into the gearbox or drag system. PENN's HT-100 drag washers are housed in a fully sealed spool to give the stopping power needed for big saltwater fish. A Full Metal Body and sideplate keep the CNC Gear System in precise alignment under heavy loads.
