SEAC IT300 1st and 2nd Stage Diving Regulator Set

SEAC IT300 First and Second Stage Diving Regulator Pack

SEAC has developed the IT300 regulator to provide a smooth airflow and ease of use for recreational and regular divers.

The SEAC IT300 membrane-balanced first stage ensures a constant average pressure. The design of the first stage allows for a natural routing of the high- and medium-pressure (HP and MP) hoses, facilitating integration with a pressure gauge, a direct-connect BCD system and an octopus

The SEAC IT300 second stage is compact and ergonomic; it features an adjustable Venturi valve to optimise the inhalation effort underwater whilst preventing unwanted continuous flow at the surface.

The unit is mounted on a braided nylon hose, ensuring great freedom of movement at the head.

The large, flexible pressure relief button on the front of the second stage is easy to operate, even when wearing thick neoprene gloves.

Diveavenue’s expert review of the SEAC IT300 1st and 2nd stage diving regulator set

“The SEAC IT300 offers excellent value for money for anyone looking to equip themselves with a reliable, high-performance set. The balanced diaphragm first stage ensures a natural, smooth breath, even at depth. The Venturi Pre-dive switch prevents blow-by on entry into the water, and the positioning of the ports makes hose routing much easier.”

Frequently Asked Questions (FAQ)

Is the IT300 regulator certified for cold-water diving? The diaphragm system isolates the pressure chamber from the surrounding water, which reduces the risk of fouling and icing. For ice diving or dives in very cold water (< 10 °C), we recommend opting for the IT500 version, which is better suited to cold-water diving.
