Sizes and uses

The Tuna Railgun is available in several lengths: 100, 110, 120, 130, 140, and 150 cm, making it suitable for a range of spearfishing techniques and conditions.

The 130 cm to 150 cm versions are particularly well suited to bluewater hunting, allowing effective shots on large predators such as tuna, amberjack, wahoo, and billfish.

Specific advantages for spearfishing

• The essential design reduces bulk and makes the speargun easier to handle underwater.
• Construction with durable materials such as aircraft-grade aluminum and stainless steel ensures long service life and reliability even in marine environments.
• The integrated shaft rail eliminates flex, increasing accuracy and the responsiveness of power transfer.
• Fast reloading lets you be ready in seconds for another shot, essential during spearfishing dives.
