Sakuma Supacast Heavy Duty Mono – 10m

Overview

Sakuma Supacast Heavy Duty Mono – 10m is a competition-quality clear nylon monofilament built specifically for constructing heavy sea-fishing leaders and traces. Unlike lighter rig-body lines, Supacast is engineered with thicker diameters and higher breaking strains to cope with powerful fish and abrasive conditions.

It's supplied as a 10-metre coil (approximately 11 yards) rather than a conventional spool, and comes in four breaking strains - 100lb, 150lb, 200lb and 250lb - with diameters running from 1.00mm up to 1.50mm. The material is described as tough yet supple, with high knot strength and high abrasion resistance built into the construction.

Each variant is clear in colour, keeping traces discreet in the water while the nylon's toughness stands up to the rigours of heavy sea-fishing use.

Perfect For

Supacast is specifically aimed at heavy trace and leader construction for powerful sea species, with tope, conger and ray named as the documented target applications. It suits both heavy boat and shore trace building where much heavier monofilament is required than would typically be used for a standard beach rig body.

Anglers targeting these hard-fighting species need a leader material that resists abrasion from rough ground, reef and the fish themselves, and Supacast's heavy-duty build is intended for exactly that kind of demanding trace work.

Technical Insight

The wide coil format isn't just packaging convenience - it's a practical design feature. Storing very heavy monofilament on a small-diameter spool tends to introduce kinks and memory, so Supacast's wider coil helps keep line laying straighter and more manageable when building traces.

The four available strengths - 100lb/1.00mm, 150lb/1.20mm, 200lb/1.40mm and 250lb/1.50mm - give anglers a choice of diameter and breaking strain to match the target species and trace requirements, from the lightest 100lb option up to the heaviest 250lb line in the range.
