Who it is for
With lengths from 60 cm up to 140 cm, the Tuna can be matched to very different hunting conditions. Compact versions suit reef and low-visibility diving, while the longest lengths are better for clear, open water and larger fish. Rinse the gun with fresh water after every dive, and inspect the bands, wishbones, bungee and shooting line regularly, replacing anything that shows wear.
