Technisub
Luigi Ferraro (3 November 1914, Quarto dei Mille – 5 January 2006, Genoa) was an officer of the Royal Italian Navy and pioneer of Italian submarine warfare, most notable for his service with the commando frogman unit Decima Flottiglia MAS. In 1943 in Turkey he attacked four ships carrying chromium ore. He was decorated with the gold medal for military valor for having sunk three enemy ships alone. Ferraro designed a number of innovations in scuba diving equipment for Cressi-sub, and in 1962 with Carlos Reinberg, he founded Technisub, a manufacturer of various underwater diving equipment. Cressi made and launched Luigi Ferraro's two most important innovations during the early 1950s. One was the "Pinocchio" diving mask, the first mask with a rubber nose pocket enabling the fingers to pinch the nostrils, facilitating ear equalization In vertebrates, an ear is the organ that enables hearing and (in mammals) body balance using the vestibular system.

Swimfin
Swimfins, swim fins, diving fins, or flippers are finlike accessories worn on the feet, legs or hands and made from rubber, plastic, carbon fiber or combinations of these materials, to aid movement through the water in water sports activities such as swimming, bodyboarding, bodysurfing, float-tube fishing, kneeboarding, riverboarding, scuba diving, snorkeling, spearfishing, underwater hockey, underwater rugby and various other types of underwater diving. Swimfins help the wearer to move through water more efficiently, as human feet are too small and inappropriately shaped to provide much thrust, especially when the wearer is carrying equipment that increases hydrodynamic drag. Very long fins and monofins used by freedivers as a means of underwater propulsion do not require high-frequency leg movement. This improves efficiency and helps to minimize oxygen consumption. Short, stiff-bladed fins are effective for short bursts of acceleration and maneuvering, and are useful fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Italian Navy
The , ) (RM) or Royal Italian Navy was the navy of the Kingdom of Italy () from 1861 to 1946.

Origins The was established on 17 March 1861 following the proclamation of the formation of the Kingdom of Italy. Just as the Kingdom was a unification of various states in the Italian peninsula, so the was formed from the navies of those states, though the main constituents were the navies of the former kingdoms of Sardinia and Naples. The new Navy inherited a substantial number of ships, both sail- and steam-powered, and the long naval traditions of its constituents, especially those of Sardinia and Naples, but also suffered from some major handicaps. Firstly, it suffered from a lack of uniformity and cohesion; the was a heterogeneous mix of equipment, standards and practice, and even saw hostility between the officers from the various for ...

Decima Flottiglia MAS
The ''Decima Flottiglia MAS'' (''Decima Flottiglia Motoscafi Armati Siluranti'', also known as ''La Decima'' or Xª MAS) (Italian for "10th Torpedo-Armed Motorboat Flotilla") was an Italian flotilla, with marines and commando frogman unit, of the ''Regia Marina'' (Royal Italian Navy). The acronym '' MAS'' also refers to various light torpedo boats used by the Regia Marina during World War I and World War II. ''Decima MAS'' was active during the Battle of the Mediterranean and took part in a number of daring raids on Allied shipping. These operations involved surface speedboats (such as the raid on Souda Bay), human torpedoes (the raid on Alexandria) and ''Gamma'' frogmen (against Gibraltar). During the campaign, ''Decima MAS'' took part in more than a dozen operations which sank or damaged five warships (totalling 78,000 tons) and 20 merchant ships (totalling 130,000 GRT). In 1943, after the Italian dictator Benito Mussolini was ousted, Italy left the Tripartite Pact. So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Set
A scuba set, originally just scuba, is any breathing apparatus that is entirely carried by an underwater diving, underwater diver and provides the diver with breathing gas at the ambient pressure. ''Scuba'' is an anacronym for self-contained underwater breathing apparatus. Although strictly speaking the scuba set is only the diving equipment that is required for providing breathing gas to the diver, general usage includes the harness or rigging by which it is carried and those accessories which are integral parts of the harness and breathing apparatus assembly, such as a jacket or wing style Buoyancy compensator (diving), buoyancy compensator and instruments mounted in a combined housing with the pressure gauge. In the looser sense, scuba set has been used to refer to all the diving equipment used by the scuba diver, though this would more commonly and accurately be termed scuba equipment or scuba gear. Scuba is overwhelmingly the most common underwater breathing system used by r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diving Mask
A diving mask (also half mask, dive mask or scuba mask) is an item of diving equipment that allows Underwater diving, underwater divers, including scuba diving, scuba divers, free-diving, free-divers, and snorkeling, snorkelers, to see clearly underwater. Surface supplied diving, Surface supplied divers usually use a full face mask or diving helmet, but in some systems the half mask may be used. When the human eye is in direct contact with water as opposed to air, its normal environment, light entering the eye is refracted by a different angle and the eye is unable to Focus (optics), focus the light on the retina. By providing an air space in front of the eyes, the eye is able to focus nearly normally. The shape of the air space in the mask slightly affects the ability to focus. Corrective lenses can be fitted to the inside surface of the viewport or contact lenses may be worn inside the mask to allow normal vision for people with focusing defects. When the diver descends, the am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ear Equalization
In vertebrates, an ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In humans, the ear is described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the auricle and the ear canal. Since the outer ear is the only visible portion of the ear, the word "ear" often refers to the external part (auricle) alone. The middle ear includes the tympanic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing. The ear canal is cleaned via earwax, which naturally migrates to the auricle. The ear develops from the first pharyngeal pouch and six small swellings that develop in the early embryo called otic placodes, which are derived from the e ...
