The concept behind the "Dyamant" shaft
It's a very hydrodynamic shaft, well finished, built with top level materials, rigid and versatile, with lowered pins, suitable also for 'closed' and 'open' head spearguns like traditonal arbaete.
We suggest, for big preys, to tie the line on the bridge, in front of the preload fin.

Dyamant shaft technical description
  • The Dyamant shaft is made in 17.4 PH rebored
  • Is made by 17.4 PH bars certificated by steelwork; straight and smooth
  • The Dyamant shaft is C.N.C. machined
  • The Dyamant shaft has 3 fins, 2 backwards (at 60/90 mm from tang) and one for preloadinga (at 200 mm from tang), for the 6.25 and 6.5 diameters, 4 fins, 3 backwards (at 60/90/120 mm from tang) and a preloading one (at 200 mm from tang) for diameter 7
  • The fins have no corners and are perfect both for dyneema use and for othe kind of wishbones
  • The recessed into barrel barb is supplied, on request, in the double - mono under - mono above configurations.

How to tie the line to the shaft
  • For all the diameters
  • It has a hole at the end and a bridge, mode out of AISI 316 steel, in front of the preloading fin that has a wide line 'pass' and therefore allows to tie the shafts also with kevlar monofilaments

Penetration cone
The cone is build in C.N.C. machined brass and has a very hydrodynamic profile; it's produced as accessory to be mounted or already installed on the shaft.
