The Summit Shuttle Docking System gives walleye trollers, Great Lakes salmon anglers, and bass fishermen a secure way to keep a portable sonar shuttle firmly mounted and easy to position throughout a day on the water. The 1/4-inch aluminum docking plate pairs with a full stainless latch-and-lock system for dependable support for valuable fish finders and marine electronics, while custom upper latch hooks pull straight down on top of the shuttle to hold it securely in place. Two pre-drilled mounting patterns provide flexible installation options for different boat setups. For boats running a 3-inch track system, the Larmac 360 and Cisco Indexable Track Mount options add full 360-degree rotation while connecting the shuttle dock to Traxtech, Bert's, and Cisco tracks, making it easy to reposition electronics toward the helm, trolling station, or working side of the boat.1/4-in. aluminum plate with full stainless latch and lock systemStraight-pull upper latch hooks securely hold the shuttleTwo pre-drilled mounting patterns expand installation optionsLarmac 360 and Cisco Indexable mounts rotate 360deg on compatible 3-in. tracksEach model is equipped with:Docking plateSide latchesUpper latch hooksShuttle installation hardwareLarmac 360 features:Larmac 360 mount and mounting hardwareMount's base is 8 in. long2 in. tallMounting patterns: 4 - 1/4 in. 82deg countersunk holes, 1 3/4 x 2 1/4 in.Cisco Indexable Track Mount features:Cisco Fishing Systems 360 Indexing 3 in.
