SEAL Equipment - Diving Gear / Equipo de buceo

US Navy SEALs use 3 main types of underwater breathing gear : open circuit compressed air (SCUBA), closed circuit (100% oxygen) (LAR V Draeger) and closed circuit (mixed gas) (MK 15, MK 16). Other US Special Operations Forces that have an amphibious capability also use these systems.

SCUBA

SCUBA (self-contained underwater breather apparatus) as used by the SEALs consist of tanks of compressed air worn on the diver's backs. They are open circuit systems which means that the exhaled air is released into the water. Seal Delivery Vehicle Team divers may also utilize the open circuit breathing systems fed from air tanks inside swimmer deliver vehicles. Aside from the size and weight of the tanks, the downside of close circuit systems is the tell-tale trail of bubbles released into the water that are visible to the naked eye and to infrared.

LAR V Draeger Rebreather

The LAR V Draeger rebreather is a closed circuit underwater breathing apparatus. Running on 100% oxygen, all expelled breath is recycled into the closed circuit where it is filtered for carbon-dioxide. The result is a complete elimination of expelled bubbles which makes the Draeger ideal for clandestine amphibious operations. With a maximum depth of 70 feet, the LAR V Draeger rebreather cannot operate as deep as SCUBA systems. The unit's relatively small size and front-worn configuration makes them suitable for shallow water operation. Dive duration is affected by depth, water temperature and oxygen consumption rate.

Closed Circuit Mixed Gas Rebreather

Like the LAR V Draeger, the MK 15 and MK 16 Closed Circuit Mixed Gas Rebreathers recycle the diver's expelled breath while filtering for CO2. Unlike the pure oxygen used in the Draeger, the MK 15 / MK 16 dilutes the oxygen supply with another gas (typically air but may also use Timux or Heliox as the dilutant). This mixture maintains a present partial pressure of oxygen (PPO2) level and allows for operation at much greater depth than the Draeger (depths down to 1,800 feet have been recorded).

Para el reenactment puede que no sea muy útil (a no ser que lo quieras llevar hasta el límite). Pero buscando información lo encontré y he querido compartirlo.

Toma ya!!

Buen post,aqui dejo un PDF sobre el LARV que tenia guardado!

Buenísimo!!

Me alegro que te guste!

lo que daria yo por pillar un LAR V-0

Toma necroposter...

Tranqui tron, hay algunos post de info como este que es normal reflotarlos de vez en cuando.

Otra cosa es por ejemplo en un post de venta de hace mil años que alguien entre preguntando.

Ya sabes que soy el vigilante del post! jajaja

Sin problema!

que es eso de los necropost?????????? sorry ..pero ya ves..la movi es que estas cosas no me interesaban mucho pero ahora toy con el buceo con varias inmersiones ya y estoy encantado con este mundo y ya que los navy seal su medio favorito es el mar pues mi interes por los combat diver ha incrementado..

No pasa nada viper.
El rebreather tiene que ser la polla.
