The DiveR fins rail kit includes 4 rubber rails suited to the DiveR spearfishing and freediving fin range. Fin rails are designed to fit to the edges of your fin blades, helping to funnel water along the length of the blade. This means each kick is more efficient, as more water is displaced by the fin.

Features:

• Designed specifically to fit DiveR Fin Blades
• Helps funnel water along the length of the blade
• Makes kicks more efficient by displacing more water
