RIO Premier Fathom Clean Sweep Sinking Fly Line - Multicolor

These designations refer to the sink rates of the line. S2/S4/Int means the line has a sinking rate of approximately 2 inches per second, 4 inches per second, and an intermediate sink rate. S4/S6/Int refers to a sinking rate of 4 inches per second, 6 inches per second, and an intermediate sink rate. The choice depends on the depth and conditions of the water.

The line is available in WF5 through WF8 sizes. Match the line weight to the weight of your fly rod (e.g., a WF6 line is designed for a 6-weight rod).

Use a nail knot or a similar knot specifically designed for connecting fly line to backing.

While it can be used in saltwater, be sure to rinse it thoroughly with fresh water after each use to prevent salt buildup and damage.

The lifespan of a fly line depends on its use and care. Inspect it regularly for cracks, abrasions, or other damage. Replace the line when its performance diminishes or damage is evident.

Use a specialized fly line cleaner, or gently wash the line with mild soap and water. Rinse thoroughly and let it dry before storing.

The different sink rates allow anglers to fish at various depths, which is crucial for targeting fish that are holding at different levels in the water column.

Ensure you are using the correct sink rate for the water conditions. Try a faster-sinking line.

Check your casting technique and ensure your leader is not too long. Also, inspect the line for damage.

Rinse the line after each use and store it properly. Avoid dragging the line across rough surfaces.
