In what ways does the buoy-style oxygen regulator operate differently from conventional scuba regulators?

The buoy-style oxygen regulator operates differently from conventional scuba regulators in a few key ways:
Pressure-reducing mechanism: Conventional scuba regulators typically use a fixed orifice to control the flow of oxygen. This orifice is calibrated to provide the diver with the appropriate amount of oxygen based on the depth of the water. However, as the diver ascends or descends, the pressure of the water surrounding the regulator changes, and this can affect the flow of oxygen. The buoy-style regulator, on the other hand, uses a pressure-reducing mechanism that senses the pressure changes and adjusts the flow of oxygen accordingly. This ensures a more consistent delivery of oxygen to the diver, regardless of depth changes.
Backup safety mechanism: While conventional scuba regulators may have backup mechanisms, such as an emergency backup inhalation valve (EBIV), the buoy-style regulator is designed to serve as a primary backup safety mechanism. If the primary regulator fails or experiences any malfunction, the buoy-style regulator immediately takes over and provides an additional source of oxygen to the diver. This ensures a reliable source of oxygen in case of an emergency, reducing the risk of decompression sickness or other dive-related problems.
Buoyancy control: The buoy-style oxygen regulator is designed to be positively buoyant, which means it floats on the surface of the water. This feature provides better buoyancy control and stability during surface activities, such as floating or swimming. In contrast, conventional scuba regulators may have a negatively buoyant design, which can make them more challenging to handle on the surface.
Easy access to backup oxygen: With the buoy-style regulator, the diver can quickly access backup oxygen by simply reaching up to the regulator and switching to the backup inhalation valve. This is not always possible with conventional scuba regulators, which may require more effort and manipulation to access backup oxygen.
In general, the buoy-style oxygen regulator is designed to provide more consistent oxygen delivery, enhanced safety backup, better buoyancy control, and easier access to backup oxygen compared to conventional scuba regulators.
