In Rob's own words
What Rob Allen says about the Tuna Roller.
2025 roller muzzle redesign
The current Tuna Roller ships with Rob's 2025 redesigned roller muzzle — lighter, more balanced, smoother release than earlier generations. A practical upgrade for the aluminium platform.
Watch Rob Allen's video →Roller mechanics — no barrel flex
Rob's 2024 Barrel Deflection Part 4 (roller muzzle): both rubbers pull the spear forward, cancelling out rubber-induced barrel flex. Means you can run heavier bands on aluminium without the deflection penalty.
Watch Rob Allen's video →Aim-point transition — give it 20 shots
Rob's Why-Is-My-Speargun-Inaccurate Part 4 specifically covers roller transitions. Aim-point shifts compared to a non-roller. Takes 20-50 real shots to recalibrate muscle memory. The gun itself is fine; the shooter's instincts need to catch up.

Common questions
Before you buy
Which length for my diving?
Under 75cm for holes and reef work. 90-100cm is the all-rounder for Thai reefs. 110-130cm for dogtooth, wahoo, and open-water GT. 140cm+ is bluewater only — you will not be able to swing it around structure.
Rail gun vs roller — what is the difference?
Railguns are simpler and more reliable. Rollers hit harder and quieter for the same gun length, but the pulley system adds maintenance. New shooters start on rails.
How long do the rubbers last?
Rob Allen amber rubber in Thailand heat lasts 6-12 months of regular use. Rinse with fresh water after every dive, store out of sunlight. Replacement is cheap and we stock all diameters.
Are these the real Rob Allen guns, or replicas?
Every gun ships direct from the Rob Allen factory in Durban to our warehouse on Koh Samui. Invoice on file with the factory for every order. Listed on the Rob Allen global dealer locator as the only authorised Thailand distributor. Grey-market gear does not carry that trail.
