## What Kind of Scuba Diving Tank Was Rob Stewart Using?
Rob Stewart was a Canadian filmmaker, conservationist, and underwater photographer who dedicated his life to protecting sharks and the marine environment. He was tragically killed in a diving accident in 2017 while filming his third documentary, Sharkwater Extinction.
Stewart was an experienced diver and used a variety of scuba diving tanks throughout his career. However, the tank he was using at the time of his death was a twinset configuration.
A twinset is a scuba diving system that consists of two separate scuba tanks, each with its own regulator. The tanks are typically connected together with a manifold, which allows the diver to breathe from either tank.
Twinsets are often used by technical divers who need to extend their bottom time or who are diving in deep or challenging conditions. They can also be used by recreational divers who want to increase their safety margin or who simply want to carry more gas.
The twinset that Stewart was using at the time of his death was a 200-cubic-foot (5.7-cubic-meter) configuration. This means that each tank had a capacity of 200 cubic feet of air.
Stewart’s twinset was filled with compressed air, which is the most common gas used for scuba diving. Compressed air is a mixture of nitrogen, oxygen, and trace amounts of other gases.
The pressure of the air in Stewart’s twinset was 3,000 pounds per square inch (psi). This is a relatively high pressure, which allowed Stewart to dive deeper and for longer periods of time.
Stewart’s twinset was equipped with a single-stage regulator. A single-stage regulator is a type of scuba diving regulator that delivers a constant flow of gas to the diver.
Stewart’s regulator was also equipped with a depth gauge, which allowed him to monitor his depth while diving.
In addition to his twinset, Stewart was also wearing a dive computer. A dive computer is a device that monitors a diver’s depth, time, and other dive-related information.
Stewart’s dive computer was set to a maximum depth of 130 feet (40 meters). This was a conservative depth limit for the type of diving that Stewart was doing.
Stewart’s dive computer also had a dive profile feature, which allowed him to record his dive profile. A dive profile is a graph that shows a diver’s depth and time over the course of a dive.
Stewart’s dive profile showed that he had been diving for approximately 45 minutes at the time of his death. He had reached a maximum depth of 120 feet (37 meters).
The cause of Stewart’s death is still unknown. However, it is believed that he may have suffered a decompression illness, which is a condition that can occur when a diver ascends too quickly from a deep dive.
Decompression illness can cause a variety of symptoms, including pain, dizziness, and paralysis. In severe cases, decompression illness can be fatal.
Stewart’s death was a tragic loss for the scuba diving community. He was a passionate advocate for sharks and the marine environment, and his work helped to raise awareness of the importance of protecting our oceans.
