YakAttack CellBlok and SwitchBlade Combo Getting a fish finder installed on a kayak without drilling holes, running wires through the hull, or ending up with a cluttered, hard-to-remove setup has always been more complicated than it should be. The CellBlok and SwitchBlade Combo solves all of that in one clean package. The CellBlok is a track-mounted battery box whose top surface doubles as a mounting platform for both the SwitchBlade Transducer Arm and your fish finder mount, keeping everything self-contained and removable as a single unit. Two track mount knobs are all that hold it in place, so the whole system attaches and detaches quickly without tools. Injection-moulded construction keeps weight down to 1.4 lbs, and enlarged cable wraps accommodate the larger wiring used in modern fish finders. A minimum of 10.5" of track is required for installation. The SwitchBlade Transducer Arm is built around a hydrodynamic blade design that minimises water turbulence and gurgle, making it quieter and more efficient than conventional transducer arms. The multi-pivot folding design collapses compactly when not in use, and the arm length is fully customisable by cutting to fit your specific kayak. Remove the middle arm section for a shorter setup, or run the full 25.75" length for side imaging transducers that need to reach well below the hull. A fish finder mount compatible with your unit is required to complete the install and is sold separately.
