Who it is for
This railgun is aimed at experienced spearfishers hunting in open water, where range, power and a stable shot matter more than a very compact gun. Longer barrels generally give more accuracy and range in clear water, while shorter barrels are easier to handle in tight reef or low-visibility conditions. After every dive, rinse the whole gun, bands and line with fresh water and let it dry out of direct sun. Check the bands and line regularly and replace worn parts before they fail.
FAQ
Which length should I choose?
Choose by the water you dive. Shorter lengths (100 to 110 cm) are easier to manoeuvre around structure, while 120 to 130 cm suit clearer bluewater hunting. If you are unsure, contact us with your typical conditions.
Can I fit a reel?
Yes. The Vecta Blue handle has an integrated reel bracket for mounting a reel.
Is it ready to shoot?
The gun is supplied rigged with bands, a 7.5 mm shaft and 1.9 mm Dyneema line, plus a muzzle bungee and long line clip.
