Im considering a new spear line and float.

Currently my freediving skills are alittle lacking and I cant imagine going after Tuna, Marlin or sharks. More like Schnapper and Kingis.

So what is a good gun to get?
Do I need one with 2 rubbers?
What about length?

Any opinions welcome.

Oh your talking guns...

you need one between 100cm and 120cm either side of this and there are disadvantages for everyday spearfishing.

with regards to the rubbers its a personal choice,the advantages of using two is that they are both easier to load plus if one breaks you still have a working gun.however using one rubber can be a lot easier.

i use rob allens and now freedivers (both 120cm) as my main guns ive shot everything from koheru to large kingfish with them no worries.
