PRO Depth Charge 3D Fly Line — Smooth
PRO Depth Charge sinking fly line gets your fly below the surface faster and reduces slack.
The Story
PRO Depth Charge is a triple density sinking fly line designed with three different levels of sink to eliminate the hinge effect in the line for better strike detection and line feel. This design allows the line to retain a tight connection from fly to angler as it sinks into the water column, reducing unwanted slack. Superb for swinging flies through fast currents or working streamers in deep stillwaters. The front section is a 30′ full sink tip (6 in. per second average sink rate based on grain weight). The mid-section is a 20′ type 3 (3 in. per second sink rate). The running line is an Intermediate with a 1.5 inch sink rate.
| Section | Length | Sink Rate |
|---|---|---|
| Front Tip | 30′ | 6 in. per second |
| Mid-Section | 20′ | 3 in. per second |
| Running Line | Unspecified | 1.5 in. per second |
FAQ
What makes the PRO Depth Charge line different from other sinking fly lines?
It features three distinct sink levels—full sink tip, type 3 mid-section, and intermediate running line—designed to eliminate the hinge effect and maintain a tight connection from fly to angler, improving strike detection and line feel.
Is the PRO Depth Charge line suitable for deep stillwater fishing?
Yes, it is especially effective for working streamers in deep stillwaters due to its consistent sinking profile and reduced slack.
How does the sink rate vary across the line?
The front tip sinks at 6 inches per second, the mid-section at 3 inches per second, and the running line at 1.5 inches per second.

Used this line for a deep-water streamer setup in a cold stream. The sinking profile was smooth and consistent. No slack during casting, and I felt strikes immediately. Great for fast-moving water where precision matters.
Virginia Scott –
Felt more responsive than standard sinking lines. The three-section design helps maintain tension, especially when swinging flies in current. A bit heavier than I expected, but worth it for the performance.

Perfect for deep stillwater fishing. The front tip gets the fly down fast, and the mid-section keeps it stable. No tangles or slack. I’ve used it in multiple rivers and it performs reliably.
