REBREATHER EXPERIENCE! Actual experience Diving with a Rebreather!
What are the real advantages of closed circuit diving? With a sixty pound package, a diver can go out on a weekend boat trip or drop off on a remote island, and can spend several hours underwater. There is no need to carry hundreds of pounds of spare tanks or take a noisy compressor that takes forever to refill a tank. A dive boat can take a load of divers out to a remote dive sight with no more gear than a normal afternoon jaunt.
CCR SCUBA divers have a subtle but advantageous ability to enjoy diving more than open circuit divers. A CCR diver doesn't worry about running out of gas. He or she is limited only by decompression. This too can be minimized by selecting a partial pressure of oxygen at 1.0 or 1.2, which virtually gives the diver limitless bottom times in 60 feet or less of water. In all practicality, a diver is not going to stay underwater over two hours at a time. Dehydration, fatigue, hunger, and attention span all come into play with bottom times extending beyond a couple of hours. So, for most shallow water diving, the rebreather diver has bottom times as long as he or she would wish for.
The CCR diver does not have a worry about overexerting or overworking the SCUBA equipment nearly as much as diving open circuit SCUBA. Worry about air consumption and overexertion eat at the open circuit diver.
The CCR diver easily adds helium to eliminate nitrogen narcosis, so the energy draining narcotic effects of depth never need occur.
Additionally, for the adventurous, closed circuit rebreathers extend the usable depth for SCUBA diving to several hundred feet.
