Extremely durable nylon monofilament for spearfishing harpoons. The monofilament is 25 meters long and has a diameter of 1.5 mm. The maximum load capacity is 80 kg.

My tip: For spearguns without a pulley, I only use monofilament to connect the end of the arrow (use the rearmost hole so that the spear does not cross when pulling back from a cave) to the speargun. A rubber element on the speargun keeps the monofilament taut.

My tip: For spearguns with a reel, I use about 4m of monofilament so as not to obstruct the trajectory of the spear. I switch to Dyneema before the line reaches the spool.
