What length rubber do I need?

If you are not sure what length you need for your speargun please feel free to get in touch. However here are the recommended stretch factors and equation to use.

Nitro 14mm is suitable for a stretch factor of 300-340%

Nitro 16mm is suitable for a stretch factor of 280-300%

Nitro 18mm is suitable for a stretch factor of 270-300%

Now for the equation:

Measure from the furthest notch/shark fin to the start of the muzzle hole
Multiply by 2
Divide by your stretch factor. If you would like 270%, divide by 2.7. If you would like 340%, divide by 3.4
= number of cm needed.

Remember that not all gun rubbers are made equally and the same is true for spears. Some spears work better when powered by a specific rubber and visa versa.

Also, be sure not to overpower your spear as this will lead to inaccuracies in your shots. Of course if you are unsure then please get in touch.
