Launched in 2017, it is still a very advanced pneumatic speargun that really needs some deep overview: the Mares Cyrano 1.3 70 with power regulator indeed contains great technical solutions with the quality standards of the great brand, Mares, today part of Head Group.

Mares Cyrano 1.3 70 complete parts

Extremely well refined and with a great design, the Cyrano pneumatic speargun line puts aside for a moment the traditional orange by Mares for a more natural and somehow fascinating blue of the rubber covering the grip and the security switch. The match with the black of all the other components and the steel of the trigger gives a final very uplevel aestethic result.

The Mares Cyrano 1.3 70 comes with a very neat, strong and useful bag containing, in addition to the speargun, a useful head cover, a pump, a threaded 66.9 mm x 8 mm diameter shaft and harpoon, a charging handle, line and a sticker.


Always a key part of any speargun, the handle has a slightly anatomical grip for both left and right handers. The key aspect is the 100% stainless steel release mechanism (100% 316L stainless steel), including the neat and visible steel trigger and lateral line release lever. The angle between the grip and the muzzle of the speargun is 117° (measured), considering for the grip the rear profile of the handle where the palm of the hand adheres and which gives the inclination of the wrist compared to the forearm.

The hand is positioned on the grip in contact with a softer rubber part for better adherence. The shape of the grip is complete with an anatomical concave area on both sides in the upper part to better position the hand.

On the upper left side of the handle we find the power regulator, while on the right the security system for the trigger is present, well made, visible, and perfectly feelable when holding the speargun, advising the spearo of the system being in block or release position. In fact, if the spearo can feel the level it means the speagun is in block mode.

The line release lever, also in stainless steel, is lateral to the release mechanism as for the most modern solutions, respect to the ones with inferior line release levers that have the disadvantage of possibly getting stuck to elements on the sea floor.

A specific screw under the trigger is used by Mares factory experts to perfectly regulate the system, and for such reason a red glue spot is positioned on the screw itself as Mares discourages any action on the system by non authorized people.

Handle base structure is made of Pa6, a plastic material with specific high level mechanical properties: excellent mechanical characteristics and excellent wear resistance, good resistance to mechanical stress even at low temperatures, fatigue resistant (it maintains its characteristics even under repeated stress and load), toughness (high resistance to compression and extension), resistance to aging and atmospheric agents, resistance to alkalis, inorganic compounds and solvents, good chemical resistance to organic compounds. As PA6 is hygroscopic, meaning it can absorb humidity, Mares uses it loaded with 15% glass fibre to reduce this effect.

The softer blue part of the grip is made of thermoplastic elastomer (TPE). The benefit of using such material is the ability to stretch, to moderate elongations and return alomost ot its original shape, creating a longer life and better physical range than other materials.

The external and the internal barrels are key for the entire functioning of the speargun. The main aspect of the design of the Cyrano 1.3 70, as for all Cyrano family, is the offset of the two, where the internal barrel is moved upward of 4 mm compared to the centre of the external one. So the distance between the line of aim and the shaft is reduced from 2 cm to 1.6 cm. This gives a good advantage in setting the line of aim, as it partially reduces the limit of pneumatic spearguns compared to sling guns: the offset of the shaft compared to the line of aim.

External barrel si made of aluminium and its dimensions are 495 mm long and 40 mm external diameter, while the thickness of the walls is 2 mm. This is also key for the resistance of the speargun, that Mares indicates to be set at 16 Bar of pressure, up to maximum 30 Bar and NOT more, but indeed the system and the security standards given by Mares request the tank to support pressure up to 100 Bar.

The internal barrel is evidently 13 mm diameter, insuring greater power, but also tougher loading process compared to the 11 mm solution, also available in the Mares line of Cyrano spearguns. In addition, oversized air passages in the internal barrel also contribute to greater power of the shot.

Length from tip of head to release mechanism is equal to 600mm.

Very compact and light (31 grams) one piece component made of anodized aluminum, the head is another key component of the Cyrano, where wider and more inclined passages help the outflow of the water moved by the piston during the shot, reducing friction and power loss, for better exit speed of the shaft.

For additional power of the shot, linked to maximum friction reduction, is the new EVO Piston, which determines increase in speed and easy loading, also due to better lubrication, the latter having the additional effect of better durability. Piston material is hardened Pom Delrin 100, insuring toughness, high impact strength, high resistance to repeated impact, high mechanical strength and rigidity, outstanding creep resistance and long-term fatigue endurance.
