Product Information
The Seac Spearfishing Pack Line Mt.5 is a 5-meter monofilament line made to reload the shafts of underwater fishing guns, offered in two versions: a transparent 1.4 mm monofilament with 4 mini sleeves, and a matt black, non-reflective 1.7 mm monofilament with 3 mini sleeves.
Who it is for
This pack line suits spearfishing divers who need to restring or replace the shooting line on their speargun shaft rather than buy a new rig. Seac states the monofilament gives greater hydrodynamics and shooting precision; the 1.7 mm matt black version is described as without reflections. Seac states the monofilament also gives a better hold on the catch without spoiling it.
