Purpose-built Y adapter

The Humminbird 720101-1 is a Y adapter cable designed for the Helix series of fishfinders. It splits a single connection so two compatible accessories can operate from one unit. The cable is sold new and carries manufacturer part number 720101-1.

Helix compatibility check

Before ordering, confirm that your Helix device uses the SIDB interface this adapter requires. Verify the port layout on your unit matches the Y splitter configuration so both branches reach their intended accessories without strain.

Ideal for dual-accessory Helix setups

Anglers running a Helix fishfinder who need to connect two SIDB peripherals at once will find this cable fits the purpose. Buyers whose units use a different connector type or who only need a single straight-through cable should look at other options.
