The HD Innovations Shuttle Docking System With Larmac 360 gives sonar-focused anglers a secure, track-compatible way to lock down the HD Innovations Shuttle when running forward-facing sonar for bass, walleye, crappie, salmon, and Great Lakes trolling applications. Made from 8mm 6061 aluminum plate with proprietary one-piece stainless steel latches, this docking system creates a strong connection point for mounting the HD Innovations Shuttle (FishUSA #279865) to boat surfaces and standard 3 in. track systems. An EVA foam top pad helps reduce vibration and thermal transfer, while the pre-drilled HDI Shuttle layout supports simple assembly without modification. Compatible with 3 in. track systems from Traxstech, Cisco, Titelok, and Fin Gear, the system requires a minimum 12 in. track length and gives anglers a dependable platform for organizing electronics and keeping critical sonar gear secure on rough water.
