Regulator First and Second Stage Combo Pairs
Most scuba regulators are sold as a matched first and second stage set, paired by serial number and tuned to perform together. This core setup provides your primary breathing source and is ready for system expansion. To complete a full recreational configuration, divers simply add an octopus second stage and a low-pressure inflator hose for their BCD. This creates a complete, balanced regulator system suitable for safe, reliable diving in a wide range of environments.
