Drennan's Supplex fluorocarbon is available in no less than 12 accurate diameters and breaking strains, from 0.075mm (0.9lb) right up to 0.30mm (10lb). Made from 100% fluorocarbon, it is exceptionally abrasion resistant, sinks well and doesn’t degrade in sunlight like standard mono can. It also has a very similar refractive index to water, making it almost invisible in clear water. Fluorocarbon is also less prone to spinning up on the retrieve compared to standard mono, making it a great choice for when you are continually casting out and reeling in.
