Help: Spear line - how strong?

[dima]

...Sorry I promise to switch back to English.
It was just a Reply To AZAPA who is advising me not to dive solo in addition to the main issue here.

Cheers.......Dima

hey Dima and all:

here is a promo video my club did:

YouTube - Promocional Club Azul

You can see me, Cressi, green fins, about 7:28 to 8:15 but a little "edited up"!(that is 2:30 to 1:42 if it shows as a count down timer.. no idea why that happens)

The disciplines you see are:
- recolecion de especias - collection of different species, winner has the widest range (all released)
- natacion con aletas - open water surface swims, 4Km ladies 8Km men
- spear fishing, we have 3 divisions

would love to see some vids of your conditions

cheers

Hey Azapa i see some pretty clear water (aquas claras) you are having there...Where is this secret spot can you give the coordinates?
I guess not.

Cheers

Dyneema is a very strong type of braided cord, it is used (in our case) as wishbone material.
The red bungee is a far cheaper alternative to the commercial rubber shock absorbers that are available. I would use about 150mm, thread one end through the snap swivels eye, tie a simple overhand knot & burr the end with a cigarette lighter. Do the same with the other end but attached to a crimped loop.
If you hunt big fish then you need a different method of attachment.
A picture would be good but my card reader has packed up so will try & post one tomorrow.

I think I have it foxy, thanks, I will post a full write-up when it's done so that others can comment and some even more beginner than I may learn. I have taken a 150mm length of bungee and spiraled the dyneema sound it, tying at both ends. It now stretches like crazy, but if it broke the dyneema spiral would be there to take the weight.

What breaking strain would you guess the red bungee to be?

cheers and a great weekends diving to all (I have 7 days off now and the tides are looking peeeeeeeeerrfect)

A couple of things:

Got some advice from SA if whipping, rather than crimping, spear-line (strimmer line/mono). Best to score the ends with a hot needle (or soldering iron in my case). This stops the loop slipping -- not an issue normally but can be if you try tugging your spear free from rocks, as I did recently -- loop closed so tight that I could no longer load).

Found the tiny local hardware store has a few sizes of strimmer mono - so picked up some 2mm (same diameter as RA Mako line), £1.90 for 15yds.

Veals: in this months Sea Angling mag (good article on lure fishing) an ad. shows "Veals Rig Nylon" in 100lb, 150lb and 250lb ratings (250lb is £6.95 for 50 yds, 150lb is £8.40 for 100yds). Veals Mailorder > Welcome to our new and improved Veals Mailorder website

I recently switch out the temporary 2.5mm spear-line in favour of the 2mm mono (I hit a huge mullet last week but the spear failed to penetrate the gill area of the fish - bounced off. Discussing this with more experienced spearos, sounds like this is to be expected from time to time. Still, always looking to improve my set-up).

I whipped the loops again & made the line 1+cm longer (more like the original RA line). I backed up the spear-end loop by adding a second whipping - which closed up more of the loop - bad idea. The size of the loop (perhaps minimum size) seems to be surprisingly critical. It stops the spear loading properly. I ended cutting away half the second whipping while in the water & will remove the rest later. Got a nice 4lb mullet this week -- not as big as the one from last week, nor as hard (hit it further back) but a nice, reassuring catch none the less.

I think Miles saidthat he uses 2 or 3mm marine grade parachute cord -- might be worth search the forum. I think one of the American spearos (Bill McIntyre?) mentioned using Dyneema. They both shoot huge fish though. Might be best to ask Spaghetti, as he is our "resident Italian spearo" - and will know what the locals use. (Anything on the Omer website?).
