• Large casing and diaphragm on second stage for improved breathing sensitivity in a variety of underwater positions
• Diver-adjustable inhalation effort knob fine-tunes air delivery to suit dive conditions
• VIVA dive/pre-dive switch prevents free flows in cold water or when used as an octopus
• Super-flow hose with oversized bore allows more air to flow on each inhalation
• High-flow exhaust valve reduces exhalation effort for better breathing comfort
• Convenient large purge button
