It would be safe to say that the Rob Allen line of spearguns is a legend in the spearfishing industry with hundreds of records and countless thousands of happy customers coming home after a successful day spearfishing thanks to Rob Allen spearguns.

Rob Allen is known worldwide for his meticulous attention to detail and testing of every change made on his guns. He does not change for the sake of it but only to continue to evolve the perfect tool for hunting our waters.

Robs methodical approach and gruelling testing in south Africa and around the world has led to a series of developments which are now industry standards.

The Rob Allen Tuna Pro Railgun is the Heavy Hitter of the Rob Allen range along with its counterpart the Rob Allen Tuna Railgun. It includes all the features needed to hunt tough scaled heavy hitting game fish and oversized reef species. When you need power and penetration this is it. Has the power to land fish well over 100kg with the versatility and agility of a single handed reef gun.

Low profile muzzle

The OPEN Rob Allen muzzle is a perfect example of efficient effective engineering. Taking the muzzle design a step further from the Sparid by opening up the site window Rob Allen has created one for the most loved muzzles on the market, fast and easy to aim. By looking closely at the key requirements for accurate shooting, ease of reloading and ease of maintenance Rob Allen worked to reduce the overall size and weight and minimise the amount of material around the spear to ensure easy target acquisition and reliable consistent aiming.

The ability to replace the factory powerbands without any tools has allowed divers to keep diving for longer. With 2 high-quality powerbands any fish any time, you’ve got the power you need.

Integrated Rail Alloy Barrel

Rob Allen pioneered the use of an integrated aluminium rail barrel into his guns decades ago to help support the shaft and increase barrel strength. This allowed for a lightweight gun with much greater power while still remaining laser-accurate. This barrel design continues on today using the highest aerospace-grade Alloys to create a reliable lightweight and efficient barrel as the backbone of your speargun.

The Rob Allen Vecta 2 handle and mechanism

The Handle and mechanism of your speargun are vital. The wrong shape and angle will result in difficult aiming and inconsistent accuracy due to recall. Rob Allen works endlessly on small minute details on his Vecta series of handles to make them a easy, accurate and reliable system for hunting fish.

The latest Vecta 2 handle offers:

Active Stainless Steel line release working off the sear, this illuminates any issues with shooting line tension, and shaft load. This result in a more consistent release and trigger pull. Ask any target shooter and repetitive consistency is the key to accuracy.

Large rounded spear through to allow a wide range of shafts and shooting lines to be used with minimal wear. 6mm-8mm shafts are no problem.

Ergonomic handle with soft touch over mold designed to direct and reduce recall and muzzle lift and give a comfortable secure and consistent grip with a natural and easy reach to the trigger. It’s all about maximizing energy to the spear and accuracy.

Solid anchor with swivel shark clip. A solid and reliable attachment point for your float line. When you get the shot on that fish of a life time you don’t want to worry about if your gun will come back.

Low profile loading butt to make loading your gun a cinch in even the roughest conditions.

2x 16mm RA Blue Powerband

What better than one great band on your gun? 2! Simple when one band just doesn’t cut it we add a 2nd to make sure. The engine for your speargun. The key to a consistent and powerful speargun is the powerband. Rob Allen has spent countless hours working on the band lengths and latex composition of his signature Blue over Amber powerbands to ensure minimal energy drop over time and consistent band stretch and energy levels. This combines to give you a reliable power output and aiming point. Combined with lightweight and streamlined Dyneema bridles these bands are magic. By tuning the band length to the sweet spot for the rubber rob can perfect the band and power for each length speargun.

Rob Allen 7.5mm Spring Steel Spear

It’s no secret Rob Allen makes the straightest toughest spears around. The spear design is classic Rob Allen and has again become a reference point for spears the world over, many times copied but never bettered.

7.5mm diameter stiffens the spear and gives more mass, this allows us to increase the power load and increase penetration.

Heat treated Spring Steel Hardened to 2100mpa resisting bending and breaking.

Machine ground tri-cut tip for busting through scale and bone

Heavy duty zinc electroplated outer coating to resist corrosion and glare

2 loading notches that are smooth and rounded to fit Dyneema bridles perfectly

drilled and smoothed shooting line anchor point

EVERY RA shaft is straightened and test by hand to ensure the straightest most accurate spear you’ll ever use.

HD spring stainless steel pin and thick heavy duty stainless steel barb, resists sheering even on the biggest fish and are all tuned to engage and lock on penetration of the fish. It’s the small things that matter, the slightest bend or out of line spear or barb has a huge impact on accuracy.

HDPE gun bungee with swivel clip and 400lb reinforced monofilament rigging

The gun bungee and swivel clip keep the shooting line at the perfect tension and allow for some give in the system during the shot and fight. The swivel clip helps when removing fish from the spear and allows for fast changeover in the event of a damaged or jammed spear. HD 400lb mono has excellent abrasion resistance and will handle a huge amount of abuse over rocks and coral.

Tool Free Maintenance and Service

The coast lines of South Africa and Australia are remote harsh environments, and lock all tools equipment should be cleaned and maintained. Rob Allen spends more time than most in the middle of nowhere hunting illusive species with very limited equipment. Rob Allens focus from the beginning was to be able to clean and replace spears, powerbands and shooting line with minimal tools. As a result, a simple wash down in fresh water, band, spear and shooting line replaced by hand when necessary is all that’s needed. Simply take a couple of spare rigged spears and some premade looped powerbands and your good for your next week long spearfishing adventure.
