• AST Plus treatment provides continuous slickness that incorporates completely, continuously migrates out, works longer, and is eight times slicker than any other slickness additive available for better shooting, improved floatation, and performance. Easily sheds dirt and oils allowing line to perform better longer
• Orvis Line ID quickly identifies the line with the taper, weight and functionality
• Enhanced welded loop makes leader attachment quick and easy while holding up to repeated use. Helps to transfer energy more efficiently to the leader allowing better turnover
• All PRO lines are 90’ in length. Depth Charge full sinking line uses 3 sink densities to help get your flies down and stay in close contact.  The tip is  30’ of Type V sink (5 ips), followed by 20’. Of Type III sink and the remaining 40’ is intermediate sink (1.5 ips)

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 in. per second sink rate.

Available in 150 grain (5/6wt mist green/dark green/dark gray), 200 grain (6/7wt yellow/dark green/dark gray), 250 grain (7/8wt orange/dark green/dark gray), 300 grain (8/9wt surf/dark green/dark gray), 350 grain (9/10wt green/dark green/dark gray), 450 grain (11/12wt white/dark green/dark gray), 550 grain (12+wt red/dark green/dark gray.)
