The Sufix Invisiline Fluorocarbon comes under the beady eye of Angler's Mail tackle editor Richard Howard. He's the No.1 products inspector, checking out loads of quality kit every week.

FLUOROCARBON leaders and hook lengths can give you an edge, especially in clear water conditions.

Available now on 20 m spools, Sufix Invisiline is 100 percent fluorocarbon, and thanks to its light refraction properties, it is virtually invisible in water.

It also sinks four times faster than standard nylon line.

It’s low stretch too, with high abrasion resistance and what the team at Sufix call a degree of shock absorption.

A useful choice for everything from drop shotting to feeder fishing and big carp when you want your line to disappear or lay flat on the deck or both.

It’s available in a useful range of breaking strains, from 3 lb upwards, offering appeal to everyone from match anglers through to the specialist and big fish anglers looking to stack the fishing odds in their favour.

Prices: 3-8 lb £5.49 (20 m); 10 lb upwards from £5.99.
