The project of the SABER SHOT 90 started with a significant increase in the inertial mass of the stems. The choice of the diameter of the shaft unfortunately suffered from the federal regulation requiring, for competitive shooting underwater, the diameter of 6.5 mm.
But this spar is not the best of the taut shot being excessively lean and therefore is subjected to the “ thorns” effect (harmonic oscillation), ballistic phenomenon that triggers at the beginning of the shooting end than continues in the first 2 meters of the trajectory of the rod. The “thorns” effect, in addition to disperse a part of kinetic energy of the rod, affect the accuracy of the shot. In the recovery of the “shot“ model for spearfishing precision, i considered appropriate, having to arm the gun with a rod 7 mm, more rigid than the corresponding 6.5 mm. One of the novelties of the Shot 90 is armament as standard with the Potentiator, propulsion system based elastomers of different diameters, already presented on this site and now successfully used by my clients on SABER or JEDI models with double elastics (or individually instead of the double circular or combined with a second circular to strengthen the shot of the speargun. It is no coincidence that the increase in mass of the shaft corresponds armament with a < flexible propulsor> more powerful, which in truth, since it was invented has proved very effective in the model 100.

While the model <100> distinguished in spear fishing on fish of small and medium size in the deeper waters, (I remember that the limit of this speargun ,encountered in my long testing,was a capture of a grouper of 5 kg to 3-4 meters away, while an 8 kg had not been pierced) the SHOT SABER 90 is designed for spearfishing in depths less difficult using the technique of fishing the most simple that a little all fishermen know the successful practice. I wanted to offer my customers e spearguns more versatile and pratical use, I would say the speargun to begin.
Who begins, or resumes practice spearfishing, needs a spearfishing simple and reliable, without complications, with a not excessive power of shot and a modest recoil, easy to load and operate at sea. I have already highlighted the facilitation loading the PONTENTIATOR that fractionates this phase in the next stretching of the 2 loaders (pieces of elastic to 16 mm in diameter) on the little fins near the shaft. The effective range of the speargun is 3 meters and half while the profit reaches 4 meters and half. The effective range is one that allows the rod to keep a good part of the initial energy at impact on the target, while the useful range is that with which it can be still achieved a good shooting accuracy and allows only the captures of smaller fishes.


I wanted to introduce the so-called multi-layer to have a constancy in the specific weight of the semi-finished wood from which derive the stem of the SABER SHOT.
In the choice of this wood species I approach much ideal weight that must have the stem to keep the speargun in neutral buoyancy. I have never written on this subject that has been a constant problem since the beginning of my experience as a manufacturer of rifles from the wooden stem: The tree from which is derived the semi-finished wood for our model of speargun has a strong variation of the specific gravity from the inside (heartwood) until you reach the outside (sapwood).

The oldest part of the stem has a highest weight of the outside that is younger and less dense. The stems of my spearguns are derived from boards of certain thickness which, depending on the cutting plane of the shaft, unfortunately exhibit significant variations in specific weight, this implies that the stems derived also from the same board to have a final weight that is very different with consequent problems of balance of the spearguns completed. If the longitudinal cutting plane of the tree, for example, is radial, namely the table from which derive the solid to the stem of the speargun was cut in the radial direction of the cylinder which can be assimilated to the shaft, between one extreme and the other of the table there is a strong difference in the density of the wood fibers, while if the tree cutting was to parallel boards the difference is smaller, but it is easier to find on the market boards obtained from a program of radial cut of the tree, because it is used in a more cost-effective for producers ( with all the problems that follow for me).

To overcome this problem and to not discard some un suitable products having a specific weight too high, and also for not balance with a lot of lead the lighter stems, I wanted to try the reed, not a technical decision for a greater resistance to stress but to solve the practical problem of selecting stems with a specific and constant weight. I want to clarify that the stems of my SABER spearguns, as they have been designed, are subject to compressive stress, not in the tip load and even less about the bending stress, so the wood is just fine and lamellar structures are redundant in terms of structural resistance.

This is obviously my opinion, although there is a widespread belief that the lamellar stems are not deformable. All the pieces of wood, solid wood or plywood which are, may be subject to deformations (twine itself, take the form of banana….and so on) even if the strips are glued with special techniques: wood species are living material that takes a long time to settle, the secret is to use naturally seasoned wood. If this doesn’t happen, even the piece of wood glued in layers, the speargun warps or cracks along the fibers adjacent gluing (which unfortunately I have had experience in the past about pilot production).

Dimensions POTENTIATOR designed for this model are:
ENGINE: 15 cm of elastic ,19 mm in diameter
LOADERS: 18 and 20 cm of elastic,16 mm in diameter SABER SHOT 90 is armed with a shaft 7 mm in diameter (but on request can be balanced for a shaft 6.5 mm) long 120 cm. It is equipped with the reel of our series with a spool of 80 cm The elastic is mounted on a single pulley with a vertical axis for a perfect balance of the traction ,both in the left and in the right one.
