Floatline Adapter for Spearfishing

Floatline Adapter is an essential component specifically designed for bluewater hunting, built to provide safety and practicality when using a speargun.

Materials and Construction

The core of the adapter is made with a Spectra core, a material with a 630 kg breaking strength that ensures high mechanical resistance and reliability in the water. The plastic coating protects the core, preventing knots and tangles from forming, while also protecting your hands from friction or cuts caused by the line running quickly.

Technical Functionality

The system allows the shaft to be quickly released from the speargun via a stainless steel Snap Swivel, essential for safety in spearfishing. This solution prevents the diver from losing the entire speargun in the event of large fish that manage to drag it away, improving control and handling of spearfishing gear.

Additional Features

• Color: Blue, easy to spot in the marine environment
• Stainless steel Snap Swivel for corrosion resistance and easy release
• Design that prevents tangles and promotes smooth handling during the dive

The Floatline Adapter is therefore an essential technical component for spearfishing, offering reliability, safety, and practicality when managing the line and speargun.

Bluewater Pro Floatline - Neptonics

The Bluewater Pro Floatline by Neptonics is the benchmark floatline for bluewater spearfishing and demanding environments. Designed and assembled entirely in the Neptonics workshop, it represents the highest standard available on the market for those who refuse to compromise on reliability and strength.

Superior construction and strength

What sets the Bluewater Pro Floatline apart from the competition is its 100% Spectra internal core, fully back-spliced. This construction technology ensures a rated strength of 1400 lb (approximately 635 kg), an exceptional value that makes it extremely reliable even with large pelagic fish.

• 100% Spectra core with full back splice
• 1400 lb rated strength (~635 kg)
• Lines from other brands are only crimped: they break at the worst possible moment
• The Bluewater Pro is the only floatline on the market with this construction combination

100% Neptonics production

Every component of the Bluewater Pro Floatline is made and completed entirely in the Neptonics workshop. No component is purchased from third parties and simply assembled: from machining the metal parts to welding, from back-splicing to final assembly and finishing, every step is directly controlled by Neptonics.

• In-house machining of the metal parts
• Welding performed in the Neptonics workshop
• Back-splicing carried out in-house
• Final assembly and finishing under the manufacturer’s direct control

Function and use in the water

The Bluewater Pro Floatline is the essential connection between the speargun and the spearfishing float. Once the fish is speared, the line works together with the float to tire out the fish and allow the diver to return to the surface to breathe, without losing contact with the fish.

• Directly connects the speargun to the float
• Allows the fish to fight against the line and float, progressively tiring it out
• Leaves the diver free to return to the surface to breathe safely
• Marks the position of the fish even when it hides on the bottom

Safety and visibility in the water

The presence of a floatline and float significantly increases the diver’s visibility on the surface, making them easy to spot both for passing boats and for their own support boat. This is essential for spearfishing safety, especially in current or when multiple spearfishers are in the water at the same time.

• The float marks the diver’s position for boats in transit
• Makes it easier for the captain to track multiple divers at the same time
• Essential in case of current drift or a fish running offshore
