Tips and Advice

The advantage of servicing your own kit is that you are more flexible to do repairs or adjustments when needed. The process is cheap, quick and easy which means that you can modify your gear when it suits you.

HOW TO TIE SPEARGUN RUBBERS:


Ingredients
  • Length of speargun rubber. Consult our band chart to determine thickness and length applicable for your gun.
  • 1 x wishbone
  • 1m dynema cord
  • 1 x lighter
  • 2 x pairs of pliers
  • 1 x wishbone inserting tool

Recipe:

1. Fit the wishbone bobble into the wishbone inserting tool

2. Apply a bit of spit or silicone spray into the rubber and insert the wishbone

3. Tie that end of the band with the dynema cord using the constrictor knot. {link to constrictor knot diagram)

  • Secure one end of the dynema into a vice grip (or get your friend to hold it with the spare set of pliers) whilst you pull on the other side
  • Apply a bit of spit to the dynema to prevent it from cutting into the rubber
  • Gently twist the rubber with your left hand whilst pulling tight on the dynema with your right hand
  • How tight? You should pull the knot as tight as you can without cutting the rubber.
  • Cut the dynema approx 3mm from the knot, then fray the end to expose the white inner cord. Singe the ends with the lighter to leave a neat and clean knot (take care not to burn the rubber).
  • Repeat the above process for the other side
  • Remember when tying the bottom rubber on a double rubber muzzle, to thread the rubber through the muzzle before tying!
  • Test the knot by pulling hard on either side of the wishbone
  • To fit the rubber to you gun, first remove the spear then lubricate the section of the rubber that will fit into the muzzle (silicone spray is ideal). Insert the rubber into the front opening first and then snap into each of the side shoots alternately, ensuring that the rubber lengths are equidistant on both sides

HOW TO RIG YOUR SPEAR LINE

Ingredients:

  • Length of monofilament line
  • 2 x stainless steel crimps
  • Spear
  • Crimping tool
  • Lighter

Recipe:

  1. Thread the line through one side of the crimp and then through the hole at the back of the spear
  2. Thread the line through the other side of the crimp
  3. Extend the fee end right through the crimp and burn the end (this serves as an extra precaution against the line slipping through the crimp, which is highly unlikely if crimped correctly)
  4. Now pull the loop down to the required size. The loop should be long enough so as that it does not restrict the spear from going into the handle and short enough so as that it does not snag the wishbone, when the gun is being loaded.
  5. First crimp in the middle of the crimp and then apply even pressure to the length of the crimp, taking care not to cut or squash the line.
  6. Fit the spear into the gun and measure 3 barrel lengths (for single wrap (and 5 barrel length (for double wrap). Add a further 30cm to enable you to work with it.
  7. Secure the free end of the line to a fixed object (such as a vice grip) and stretch the line. (Monofilament is naturally stretchy and this process removes that initial stretch, thus preventing you from having a loose spear line after shooting your first big fish).
  8. Thread the line through the muzzle, down and around the line release clip and back up to the line clip.
  9. Pull the line tight and measure where the loop should go.
  10. Fit the crimp and repeat the process in 3 & 5 above.
  11. Always ensure that the spear line runs on top of the spear and is not looped around the spear as this will cause it to snag upon firing.
