Platypus has been making the world's strongest and best fishing lines since 1898! Platypus Pre-test offers confidence that no other line in the world has the guts to do, with the highest test written in black and white on the spool. Every 1000 metres of Pre-test is tested three times. Just because Platypus has been around for over 100 years does not mean that it has remained the same. Platypus is constantly updating techniques, and developing new nylon resins and additives to bring you the best possible nylon monofilament in the world. Platypus Pre-test has an engineered stretch, which acts as a shock absorber for those long battles with trophy fish. Platypus uses its exclusive hard annealing process to provide excellent abrasion resistance, and the reliable quality that comes from the oldest and best fishing line company in the world!
