second band for cressi comanche 90?

[Dave_spearo]

I have cressi comanche 90 with 6,5 mm shaft. I want to ad a second band to my speargun. I have search in local store but they don't have circular band for cressi comanche.
Here we have only have cressi, ommer and riffe dealer.
Any suggestion?
Thank you

Take your gun to the local store.
Find the wishbone that will work nicely for the notch on your spear.
Then choose the length of the band that goes with that wishbone, if premade.

It does not have to be Cressi, as long as it works.
I even used dyneema line (steel wire?) instead of wishbone on notched spears (but you have to be carefull with this, as the line can be easily cut on the notch).

So, in a word - improvise.

I wouldn't bother. Adding another band will overrpower the gun, causing severe inaccuracy, losing power through bending of the spear, and recoil lifting the muzzle and pushing the spear off target. For a 6.5 shaft you need only one 16 mm or 17.5 mm band

Thank you for prevent me making mistake.
