Gemini Zip Sliders

Overview

The Gemini Genie Zip Slider is a compact T-shaped running ledger boom designed for building running rigs in sea fishing. The mainline threads directly through the solid plastic body, while the sinker attaches separately to a large integral clip projecting from the side.

This simple but effective design creates physical separation between the lead, the mainline, and the hook trace, rather than having everything converge at one small connection point. The body is described as strong, durable plastic, giving the slider a robust running surface for the line to move against.

Each pack contains 5 Zip Sliders in red, ready to be built into a running ledger arrangement alongside a buffer bead, swivel, and hook trace.

Perfect For

Gemini Zip Sliders are particularly associated with boat fishing, where anglers lower a lead to the seabed while fishing a baited trace behind or alongside it. The running arrangement means the lead isn't fixed directly to the terminal swivel, which is especially useful when weight requirements change with tide and depth.

They're also suitable for shore-based running ledger rigs where a running arrangement suits the setup, though they aren't intended as a dedicated distance-casting component. A typical running ledger rig runs: mainline through the Zip Slider, then a buffer bead, swivel, and hook trace, with the sinker clipped to the slider's side connection.

Technical Insight

The T-shaped body is the key to how the Zip Slider works: the mainline passes through the central section while the sinker attachment projects away from it, keeping the lead physically separated from the trace. This separation helps reduce the risk of tangles, particularly useful when dropping a baited rig from a boat where a heavy sinker and long trace could otherwise tangle as they descend.

The plastic body also provides a running surface for the mainline, giving minimal abrasion as the line moves through the slider during use, rather than the line running against a bare metal connection. The large integral clip makes swapping to a heavier or lighter lead quick and easy without rebuilding the whole terminal rig, a genuine advantage when tidal flow changes through a session.
