The Essential Link

Nylon fishing line is probably your most vital piece of equipment and yet many anglers know little or nothing about what it is, how it is made and the properties of this critical element of tackle that make it so good as a fishing line.

In this section we explain the key facts about monofilament, what it is, and what influences your line when fishing.

We also dispel some common myths and misconceptions.

Nylon monofilament is is an extruded polymer that is durable, resistant to ageing and rot proof. It is very stable and is not affected by microorganisms or other naturally occurring substances. It is totally saltwater resistant. The specific gravity of nylon is only slightly heavier than water and therefore tends to sink slowly when submerged. However, it does not usually have the ability to  break water's surface tension on its own.

Nylon Monofil has been used as the main material for fishing line for around sixty years and it is supremely suitable for the purpose for many reasons. Its great strength to its diameter, its suppleness and the fact that it has balanced stretch factor that means that it gives good response to bites but still enough cushion to avoid crack off caused by sudden strikes and lunges from powerful fish. This last factor means that a much lighter lines can be used to catch large fish.

Nylon fishing line has developed significantly in the last 20 years with the introduction of copolymers which have higher numbers of bonds within the material making it significantly stronger.

All Ultima products are made from copolymers.
