lines for speargun and buoy

[DeepAbyss]

hi,
i have cressi sl 40 i spear in depth 1-7m the fish weight 0.2-0.7 kg.
which line is better to the speargun Monofilament or dyneema pros and cons(and width line reccomend)?
which line be a good line to attacht the buoy and the speargun a float line(20-30m), not get tangled and not need to replace often and what width of line?

thanks

I always use a dyneema for my speargun, monoline is to ridget for me.

As for the float line i made my own.

Floatline- How to prevent tangling and how to shorten them...

Nice post MozSpearer. I've seen SA spearos recommend this approach before. So that's a clove-hitch that you use to hold the coils?I tried using the Omersub's yellow line winder but it is too big & bright IMHO (makes a great winder for a kayak anchor rope though ;)) & some plastic cable...

For float line, I am currently shopping for what is called a "float line". Strange name for the line that is used to attach the float. Never had one before, so I can't speak from experience, but seems like the way to go, stiff and slippery.

I think mono is better for attaching the shaft, it must have less hydrodynamic drag. I use mono on all my spearguns now.

Monofilament would be recommendation for spearline: cheap, strong, slightly stretchy and, thicker more rigid lines tangle less. 1.5mm - 2.0mm is normal (e.g. 2mm RA Mako line rated at 400lb!). Foxfish has been experimenting with finer spearlines but I am happy using thicker lines which can withstand more abrasion, cuts and gouges.

For floatline, I look for something that floats and is fairly rigid to reduce tangling. Rob Allen's green polyester rope line ticks
all the boxes for me. For you, 10m-15m would likely be ideal but you can easily temporarily shorten a 20m line, or cut I. RA floatline used to be keenly priced, less so now in UK but you may be able to find this polyester rope elsewhere ( sometimes called Thai curry green rope). I bought a decent sized roll of it for 50p in a carboot sale. I also found some some washing lines made out of similar polyester rope, slightly thinner and lighter color green ( or red) for £1 each, made in England too. I bought a few but realistically a floatline of this type will last you a lifetime, and your descendents
