Alternate Air Sources
An integrated air source combines the features of a power inflator and alternate air source.
Integrated Air Source
Another alternate air source that's gaining popularity is the integrated air source. This is a BCD power inflator with a fully functional 2nd stage built into it. This option is popular because there are no extra hoses or equipment to deal with.
In the event of an out-of-air emergency, the donor breathes from the integrated air source while the buddy breathes from the donor's primary 2nd stage. This procedure is different than what most divers are familiar with, so always be sure your buddy understands this air sharing procedure before beginning the dive.
Like the octopus, integrated air sources share one air source between divers, so be sure to monitor your air supply when sharing air.
