Who it is for

A rollergun gives a long power stroke from a compact barrel, so the Tuna Roller suits divers hunting pelagics and larger fish who still want a manageable gun. Shorter lengths of 80 and 90 cm handle well around structure and in limited visibility, while 100 to 120 cm guns suit open water. Rinse the gun, rollers and bearings in fresh water after each dive and inspect the bands and line regularly.

FAQ

Does the gun include a reel?
No, a reel is not included, but the Vecta2 handle has an integrated reel mount.

What does the 6 times barrel length range mean?
The setup provides an effective shooting range of approximately six times the barrel length, measured from the tip of the muzzle.

Which length should I choose?
Pick a shorter gun for reef and low visibility and a longer one for clear open water. Contact us if you would like help choosing.
