CellBlok system is the simplest solution on the market for attaching a fish finder to a kayak, and to make it even easier we now offer the CellBlok paired with our SwitchBlade Transducer Arm. To complete the install all you need is a YakAttack fish finder mount compatible with your make and model of fish finder and a battery. CellBlok Info: Depthfinder installation on kayaks just got smarter. The YakAttack CellBlok is a track mounted battery box and its top surface serves as a mounting platform for the YakAttack SwitchBlade Transducer Arm and YakAttack fish finder mount. No more drilling holes in your kayak or routing wires! Simply loosen the two track mount knobs and the CellBlok allows you to quickly and easily attach or remove your depthfinder. A minimum of 10.5" of track is required to attach the CellBlok. This updated version of the CellBlok was new for fall 2020 and features an injection molded construction compared to the original model. The change in material has resulted in a 25% weight reduction (now 1.4 lbs) and we also increased the size of the cable wraps to accommodate the larger wires used in today's fish finders. Interior Space - 6.375'' x 4.25'' x 2.60'' Exterior Dimensions - 10.25'' x 6.75'' x 3.50'' SwitchBlade Transducer Deployment Arm Info: We knew it was time we developed a transducer deployment arm that is truly designed for the task, and the SwitchBlade Transducer Deployment Arm is exactly that. The SwitchBlade pairs perfectly with the CellBlok and family of YakAttack fish finder mounts. We designed the blade to minimize gurgle and resistance, making the SwitchBlade the most efficient transducer arm on the market. The patented arm folds up compactly. No more cumbersome, rigid arm to deal with. And for the angler that really wants to dial it in to fit their boat perfectly, we made the length of the arms customizable and can easily be cut to length to accommodate nearly any kayak on the market. Unlike other transducer deployment arms of the past the new SwitchBlade Transducer Arm from YakAttack is focused on speed and adjustability. Featuring a hydrodynamic blade design the SwitchBlade causes less water turbulence resulting in a faster and less noisy over-the-side transducer mounting solution. Even when the SwitchBlade Transducer Arm is mounted on top of the YakAttack CellBlok the overall length reaches deep enough below the hull of your kayak for side imaging transducers to scan as designed. If you don't need the full length of the SwitchBlade simple remove the middle arm and now you have a customized solution. To deploy or retrieve the transducer arm the SwitchBlade features a unique tubular design and multi pivot allowing for easy articulation in and out of the water. When mounted to the top of the CellBlok the base of the SwitchBlade serves as the mounting platform for any of our YakAttack fish finders mounts. When doing the install simply use the longer t-bolt included in the kit and then you are LockNLoad ready. This system is compatible with YakAttack MightyMount’s, GearTrac, and most other factory installed kayak track systems and aftermarket track from Scotty Fishing Products, RAM Mounts, and YakGear
