Neptonics Stretch Floatline

Overview

The Neptonics Stretch Floatline is an elastic bluewater spearfishing floatline designed to apply progressively increasing resistance during the fast runs of soft-fleshed pelagic fish. The controlled stretch helps reduce abrupt loading at the spear connection while maintaining a streamlined floatline setup.

Progressive load control

Stretch is distributed along the floatline rather than concentrated in a short bungee section. As a fish runs, the line elongates and resistance builds progressively before the hard float takes the full load. This smoother transition helps limit the sudden shock that can contribute to a flopper or slip tip tearing free.

Rigging and use

The floatline is intended for hard-float bluewater systems and is particularly applicable to fast-running species such as wahoo, kingfish, and dogtooth tuna. Its internal load-bearing cord uses spliced construction to avoid knot- or crimp-based terminations in the cord.
