The Rob Allen Tuna Pro Railgun is a band-powered speargun for reef and pelagic spearfishing. It pairs a blue camouflage aluminium barrel with two 16 mm rubbers and a 7.5 mm spring-steel shaft. An open muzzle, integrated shaft rail and Vecta2 handle complete the setup. Choose from 100, 110, 120, 130 and 140 cm barrel lengths to suit your diving conditions.
Features and benefits
Aluminium rail barrel with blue camouflage
The aircraft-grade aluminium barrel has an integrated rail to support the shaft and a 1.45 mm wall thickness. A blue camouflage wrap gives the Tuna Pro its distinctive finish.
The low-profile open muzzle keeps the sight line clear. It also lets you replace the rubbers without tools.
Twin 16 mm rubbers and a 7.5 mm shaft
Two Rob Allen blue-over-amber latex rubbers are fitted with Dyneema bridles.
The 7.5 mm shaft is made from oil-quenched carbon-alloy spring steel. It has two smooth loading notches, a tri-cut tip and a heavy-duty stainless-steel barb. Zinc treatment helps protect the shaft against corrosion. A smoothed attachment hole reduces wear on the shooting line.
Vecta2 handle and supplied rigging
The Vecta2 handle has a soft, textured grip and a stainless-steel line release. The release works from the sear, the part of the trigger mechanism that holds the shaft. A loading butt provides a broad contact point when loading.
The supplied black 400 lb monofilament shooting line resists abrasion. It connects to a gun bungee and swivel clip for easier shaft removal and re-rigging. A reel bracket is fitted as standard.
Warranty
Rob Allen provides a limited lifetime warranty on the handle, trigger mechanism and barrel, subject to its warranty terms.
Care after each dive
Rinse the unloaded speargun in fresh water after use, including the trigger mechanism, muzzle, bungee and line release. Dry the shaft before storage and keep the gun out of direct sunlight and heat. Inspect the rubbers, Dyneema bridles, shooting line, crimps and shaft for wear before your next dive.
