The YakAttack CellBlok Fish Finder Combo delivers hassle-free sonar installation for kayak anglers. This all-in-one system combines a track-mounted battery box with an integrated mounting platform, eliminating drilling or wire routing through your hull. The SwitchBlade Transducer Arm features a patented hydrodynamic blade design that minimizes water turbulence and reduces noise for cleaner sonar readings. The arm deploys and retracts smoothly with a unique tubular design and multi-pivot system, then folds compactly when not in use. Customize the arm length to fit your kayak by simply cutting to size. Built from injection-molded construction, the CellBlok weighs just 1.4 lbs—25% lighter than previous versions—while accommodating larger modern fish finder cables. The system requires only 10.5 inches of existing track space and works with any compatible YakAttack fish finder mount and battery. Installation takes minutes: loosen two track mount knobs, secure the CellBlok, attach your transducer arm and fish finder mount, and you're ready to fish. Remove or reposition components instantly without tools or permanent modifications to your kayak.
