Humminbird Splitter Cable: Side Imaging & 2D Sonar for HELIX – 9 M SIDB Y

Meet the Humminbird Splitter Cable, a compact Y cable that lets you run a Side Imaging transducer and a DualBeam 2D transducer to one HELIX control head without a switch box. This setup unlocks new possibilities on the water by feeding two powerful transducers into a single interface, helping you interpret terrain, structure, and fish targets with more context.

What it does

• Combine Two Transducers: The Y cable lets you use a Side Imaging transducer and a separate DualBeam 2D transducer on one unit without a switch
• Improved High Speed Performance: When used with a 2D transducer, you can achieve crisper depth readings and steadier bottom tracking at faster boat speeds
• Wide Compatibility: Works with Humminbird Side Imaging or Down Imaging products, with MEGA Side Imaging support
• MEGA Side Imaging Ready: Fully compatible with MEGA Side Imaging technology where supported, enabling broader imaging at depth
• Simple Rigging Solution: A 30 inch cable helps you position gear for clean, reliable connections

Compatibility notes ensure you can adapt this to many HELIX setups. It works with most Humminbird Side Imaging or Down Imaging transducers, except for APEX, SOLIX, or ONIX models. It is MEGA Side Imaging compatible where supported, giving you the option to access wider imagery from compatible transducers.

Real world use cases

Imagine a bass boat cruising through a mixed seabed and weed edge. Side Imaging paints a broad picture of structure, while the 2D sonar delivers precise depth cues under the boat. The combination helps you form a richer understanding of what lies beneath, all from a single console.

• At speed bottom tracking: The 2D transducer adds depth cues to help you monitor bottom changes while you cruise
• Structure and habitat scouting: Side Imaging highlights submerged ledges, weed edges, and drop-offs for targeted findings

Simple setup tips help you get the most from the splitter cable. Route the 30 inch cable cleanly, secure connectors away from gear and knots, and keep transducers oriented per your unit’s guidance. With a tidy rig, you can enjoy quick swaps between imaging modes and maintain a streamlined cockpit on the water.
