Bluewater Hunting

Slip-Tip: Detachable tip for spearfishing and bluewater hunting

The Slip-Tip is an advanced tool for spearfishing, designed with a front tip release mechanism. This technology allows the tip to detach from the shaft once it has penetrated the fish and to position itself crosswise inside the flesh.

This technical feature prevents the fish from levering against the shaft, reducing the risk of breakage or tear-out of the spearfishing gear during retrieval.

Technical features and applications

• Recommended for ocean bluewater hunting and fast, powerful pelagic species with soft flesh, such as Wahoo.
• Ensures greater holding power even when the fish is not fully penetrated, thanks to the crosswise positioning of the tip in the flesh.
• Reduces the chance of losing the fish by increasing the effectiveness of the spearhead in dynamic and demanding hunting situations.

The Slip-Tip is therefore an essential component for spearfishers targeting demanding pelagic species, ensuring efficiency and precision when retrieving the catch.
