High quality pure latex Ø14~19mm Magnum Plus rubber band for spearguns (sold by the meter).

Highly elastic with extra high stretch factor, ensuring an exceptionally smooth shot.

The Magnum Plus rubber band consists of four layers:

The first layer consists of iridescent metallic copper which allows color / shade reactivity of the rubber band to match and blend in the surrounding environment.

The second layer is designed to block UV rays from penetrating the rubber and deteriorating the internal natural latex over time.

The third layer consists of high modulus natural rubber and functions as a knot resistor, enhancing the overall durability of the Magnum Plus rubber band.

The fourth and final layer consists of pure natural Latex rubber.

Thanks to this layered structure, pure Latex can be used at the core of the rubber band without the use of any additives which are found in traditional rubber bands and compromise the performance of natural Latex.

The Magnum Plus rubber band are also made with smaller internal hole diameter than traditional rubber bands (0.9mm), allowing for a greater quantity of pure Latex material without increasing the overall diameter of the rubber band - thus offering higher power output at the same rubber band diameter.

Thanks to it's unique structure, the Magnum Plus rubber band has a unique capacity to store the load for long time at high elongation (up to 350%).

We strongly advise setting the rubber bands to elongation factor of 300% with your speargun for optimal stability and performance.
