Sunline FC Sniper Invisible does not flash underwater like other fluorocarbon lines can and do. 100% high grade fluorocarbon, Sunline’s FC Shooter Invisible has been specifically formulated for high pressure fishing situations and has the invisibility and suppleness to fool even the most fickle fish. With the line colour alternating every 15cm which helps it disappear around structure or cover and reduce the spook factor. The 5 alternating colours every 15cm of the line are Natural Clear, Moss Green, Gray, Green and Reddish Brown – to blend in with the colour of weeds, rocks, trees and stained water.
