tool kit

In your MAKO Spearguns Attack Pack Tool Kit you will need:

  • D) Pliers
  • F) Scissors
  • H) Lighter

You will also need:

NOTE: Bridle wishbones are to be used only with shafts with "Sharkfin Tabs", Pinned Tabs" or shafts with "rounded notches". "Unrounded notched shafts" will cut through bridle wishbones.

WARNING: Some speros will file their notches to accept bridle wishbones, however this process weakens an already weaker shaft and increases the chance of a broken shaft.

MAKO Spearguns offers only high quality shafts with "Sharkfin Tabs" that are almost 50% stronger than notched spears.

Use band tying line to tie a constrictor knot. Line up constrictor knot and use pliers to tighten know. YOU MUST PULL HARD! Then turn tubing over and tie a 2nd constrictor now on the back side of the tubing.
NOTE: For photographic reasons, we use high vis line. Actual band tying line is much thinner and black in color.

After tying the second constrictor knot on the opposite side of where the first constrictor knot was tied, remove excess material and burn ends to prevent fraying
