Product description of SEAC IT500 300 DIN diving regulator set

Description summary

Experience superior performance with the SEAC IT500 regulator set, engineered for optimal performance and ergonomic comfort. The lightweight, balanced diaphragm first stage is EN250 A certified for cold water, delivering high airflow at any depth through 2 HP and 4 LP pre-oriented ports. The second stage gives you total control with an adjustable breathing effort knob that eliminates free flow. Its unique exhaust deflector keeps bubbles from your field of view for clear, unobstructed dives. This premium set includes a semi-rigid protective case

The brand-new IT 500 regulator is one of the best regulators on the on the SEAC range.

It features many of the technologies available on the market that optimise performance without compromising ergonomics and ease of use.

It has an ergonomic knob integrated with the dive/pre-dive lever to regulate breathing effort and optimise the Venturi effect, eliminating the annoying phenomenon of free flow if the regulator is left in the water.

The generously sized purge button, made of soft PU in 2 materials enhances the SEAC logo, is an integral part of the front shield embellished with a steel ring, optimises both operations even with thick gloves, and the passage of water, reducing breathing effort and avoiding, provided by the front and side openings, possible free flow due to the force of currents that are deflected by the front cover.

The Exhaust deflector thanks to its unique geometry, this feature prevents water ingress into the second stage through the exhaust valve, even in the presence of strong side currents and at the same time, conveys the expelled bubbles to the sides of the face, avoiding annoying exhaust bubbles in front of the field of vision, with consequent reduction of the same.

The first stage is hot forged and machined using computerised machining centres to reduce its weight as much as possible, and has all the outlets, both HP and LP, ergonomically pre-oriented for all the components connected to it:second stage, octopus, pressure gauge, jacket LP Hose, dry suit LP Hose and transmitter, thereby facilitating different configurations.

The matt chrome finish enhances its aesthetic appearance.

It is a balanced diaphragm First Stage with high air flow and high performance through all depth ranges.

The First Stage features 2 high pressure ports and 4 low pressure ports.
