Apeks is known throughout the world for dive equipment of quality, craftsmanship and durability. Due to innovative design and the use of advanced materials, Flight regulators meet Apeks' high standards. They are tough, reliable and strong enough to cope with the demands and rigors of traveling. Flight is suitable for diving in water with a temperature above 50Â°F / 10Â°C. This is perfect for those warmer, exotic travel destinations, but Apeks confirms it is equally suitable for waters as cold as 50Â°F / 10Â°C. They are the most compact Apeks regulators ever made â€“ small yet fully loaded with high performance and comfort. Flight is ideal for every dive journey from a visit to your local dive site to an exotic trip overseas.
