Canova 95 Carbon speargun

Something a bit different in terms of the gun body cross section. Wide and flat at the rear end and tapering inwards towards the muzzle.

Canova 95 full carbon speargun
Inverter-roll speargun with an elegant and modern design, with sinuous shape inspired to the masterpieces of the great Italian neoclassical sculptor Antonio Canova.
The study of the geometries and volumes, besides than aesthetical, is aimed to the balance of loads, to the maximization of the flexural stiffness and to the minimization of the recoil.
These astonishing features are designed in order to improve accuracy, precision and the easy to use.

Material
Monolithic high modulus carbon fibre, closed and hollow structure.
The internal core structure is made of a polymeric multifunctional material with low density, with structural performance suited for Aerospace applications. The close cell polymer core is also designed to damping vibration during shot.

Shape
CANOVA 95 has a cuttlebone shape, very thin in the tip. On the upper side, next to the integral shaft rail, two channels to hide rubber bands can be observed, and two very inclined planes with above the name of the gun CANOVA 95 and CETMA COMPOSITES logo in ancient gold letters.
On the lower side there is a unique cannel to contain the propulsive system of the rubber bands. On its sides there are two inclined planes that connect to the superior ones to create the cuttlebone shape.

Dimensions
Very thin thickness, only 18 mm as mean, with minimum thickness of only 12 mm. Wide variable from 100 mm in the reel area to 49 mm in the tip area.
Shot useful length 95 cm

Finishing
Anti glare matte. All CETMA COMPOSITES products are NOT painted, this is quality warranty. In fact often low quality product are painted to cover defects resulting from poor processing.
Manufacturing
The very innovative manufacturing process, discovered and studied by CETMA COMPOSITES and named “ZERO DEFECTS TECHNOLOGY”, allows the production of a totally monolithic carbon composite component with zero voids content.

Propulsion system
ZR is for “zero recoil” system.
CANOVA is a roller provided with the well-known ZERO (zero recoil) propulsive system also referred as Y system from the way to assemble rubber bands.
This system is made with a pair 14 mm rubber band with “controlled elongation” running on a pair of high-performance pulleys on the upper side. These upper rubber bands are connected to two couple of high power 16 mm rubber bands located on lower side.
During the shot a higher rubber mass moves toward the shooter balancing the shaft movement thus resulting in high stability and recoil reduction.

Standard accessories*

CANOVA speargun is always supplied full accessorized and ready to fishing.
Standard mounting includes:
-7 mm Tahitian shaft with double barbs, made of 17.4 PH rebored stainless steel tempered tempered up to 49 HRC hardness.
-Camera mounting system;
-carbon reel with 50 m of dynema;
-assembled ZR rubber bands system made with new higher power MAGMUM PLUS rubber by CETMA COMPOSITES.
*all accessories are always included in the selling price.

Re: Canova 95 Carbon speargun

The design has a channel underneath to locate the rear end of the band battery with the bodywork sides curving down to partially cover it. The gun body is shallower than expected at the rear, however carbon fiber construction stops it becoming a leaf spring and those curving down side sections most likely help to stiffen it up. Reminds me of a stingray pointing the other way.

Nice find, Pete.

Here are just a few more images I found, though fairly low res, the do show the shape a bit more:

If it shots as well as it looks, it is going to be a winner!

Re: Canova 95 Carbon speargun

was only a matter of time before the Cetma crew birthed their own Fucile Carbono.
Not a rollergirl myself, but looks fantastico!
do love their fins

Re: Canova 95 Carbon speargun

Rather reminiscent of the Alemanni carbon rollergun with the two component bands, the front 14 mm "controlled elongation" internal cord limited bands attaching to twin 16 mm bands anchored at the rear in two groups. Sheltering the lower band run in the bodywork is a good idea, although at the back the influence on drag is much less than it is at the muzzle when traversing the gun. Seems to be single stage loading. The rear band anchors appear to be hidden under the base of the reel, so no chance of hooking them separately if say the 16 mm paired bands were split so that the inner two were always hooked up and you put the outer two on later in a second stage loading.
