Hi All

I recently delved into the dark side and bought a Sporasub One Air 110 with 7 mm shafts and the One Reel. I intend to use gun together with my RA Tuna guns. My target fish are West Australian reef & pelagic fish up to 20 kg.

As I haven't owned a pneumatic speargun since the early 1980's (Nemrod), I wanted to asked whether it is preferred to run dyneema from the reel all the way to the shaft or have a few mono wraps then a clip and then onto the reel dyneema.

Any advice would be much appreciated.
 
I have four wraps (eight lengths!) of 1.33mm Asso/Ace Triple Force mono (up from 1.17mm) on mine and then Salvimar dyneema on the reel. I don't know if I should believe the hype but that particular brand of mono is supposed to be good quality but obviously a lot of people would go for a thicker one.
I like that I can unclip the mono from the reel line in those instances when I can't easily pull or thread the spear back out of the fish.

You may find that the One Air shoots so far that the line release itself becomes too short to securely hold the amount of wraps the gun can actually pull.
If that's the case, you can consider making a longer one. I did that and there's a post here:

Hi Diving Gecko
Many thanks for the valuable information. I might end up using Rob Allen mono as I have large quantities of it.
Cheers

Hi there,

That ties in with a query I have- lost a big baldie + spear yesterday when the 130 lbs mono 'leader trace' snapped ( it did go around a coral head) . I used mono (two wraps) as a leader because of information it improves range & power. But this is the third time a good fish escapes me because of mono.
I thought it better to lose some range rather than fish. I have gone back to Salvimar Dyneema but rub some silicone grease on the first couple of metres to streamline any furriness.

Is 130 lbs too weak? I have used a different brand of similar strength before. Could it be that mono- while strong enough- has limited abrasion resistance when used around reef?

Hi Kees

I think your mono is far too weak. I use Black Mako Shooting Line (Rob Allen) which has a 350 lb breaking strain and I haven't lost any fish due to line breakage in many years.

I like your idea of greasing the dyneema which might just reduce friction.
 
Thanks Peter,

Just eyeballing the mono on my RA- it is thicker than the dyneema I use on the pneumatics which I believe is 1.5 mm- which has never suffered any significant abrasion damage.
Because I was using the mono for less resistance, I was reluctant to use a much larger diameter. I may have been wrong in that.

At what stage does the required diameter of mono start to outweigh its lower resistance per diameter?

Regards,

Kees
 

Hi Kees

2 mm mono should have less resistance in water than 1.5 mm dyneema. I would not use less than 2 mm mono on a shalf.

Cheers

Peter
