The Arc4 line has been designed to create an underwater arc through the mid zone. The belly of the line sinks quickest at 4ips creating this under water arc. This is a great searching line which covers multiple depths. The Arc4 allows you to fish the drop, plain, hang and lift all in the same cast. These lines have been designed to be very user friendly in the hand and cast long distances. Despite the fact this is a sinking line we have made the 20' tip section olive to try to eliminate spook as much as possible. At 20' the line changes to a dark olive, this colour change is designed to help you hang your flies at the same depth time after time. Once the colour change hits the top rod eye you hang at 20'. Once the colour change enters your hand you will be hanging at 10'. The Arc4 shares its colour scheme with the other Arc lines in the Tactical Advantage range. This is a great advantage to competition anglers. The Arc lines are mounted on a low stretch core helping them cast efficiently and transferring every little knock to the finger tips which is important when fishing at depth. Line 105' long.
