Please email enquiries@spearfishing.co.uk if you have any special requirements.  Also note that these band lengths are designed for Rob Allen gun configurations.


Rob’s gun rubber is manufactured using the dipping process.  While this costs more to make, it was a conscious decision not to cut corners like other manufacturers and to stay true with the RA ethos.  This result is a technology that lasts longer and out performs its competitors.

The trade mark blue colour of RA rubber is more than just a brand feature.  The chemical composition increases the protection from the harsh ocean environment and boosts performance.  We use less additives giving a purer long lasting performance.

Do you know why Rob Allen guns are so powerful?

The main difference that makes RA more powerful over the typical European gun is the type of latex used for their bands but its a big difference.  If you look at Euro rubber it will mostly be a block colour (often black throughout), if you look at RA rubber you will see its a natural gum colour and has rings in it like when you cut a tree in half, this is down to the way its manufactured.

Most Euro gun rubber is made via an ‘extruded’ manufacturing process like squirting toothpaste out of a tube, the thickness is dictated by the size of the hole.  This is much cheaper to make in comparison and the quality suffers because of the additives needed to cure it quickly.

Extruded rubber is about 30% cheaper on average but has poor notch toughness.

By comparison RA latex is made via a dipping process like how you make candles, the latex is repeatedly dipped until the correct thickness is achieved.  For this process you can only use 100% pure natural latex (tree sap).  This is why its always gum coloured.  The blue outer colour is a UV protector to prolong the bands life.

The best elasticity comes from pure latex. The purer it is the better.

RA bands are made with the purest latex, this does make it expensive though – but do you buy a fantastic gun and then fit cheap rubber?

RA have tested most manufacturers from around the world and only use what they have found to be the best. When loaded and held at a specific stretch, all rubbers lose their elasticity to some degree, some more than others. Poor rubber can lose as much as 30% over 1 hour.

A fun fact that not many people know 🙂
