Vai al moduloThe Seac IT500 Black Set is Seac's top-of-range set: it combines the IT500 Black regulator (first and second stage) and the IT500 OCTO octopus, with the Mate Reg bag included. Available with a DIN 300 bar (4350 psi) or INT 230 bar (3335 psi) connection, it is EN250A certified for cold water and made in Italy.
Set contents
- Seac IT500 Black regulator: balanced diaphragm first stage and balanced second stage
- Seac IT500 OCTO octopus with high-visibility yellow front cover and 1 m (3.3 ft) braided hose
- Mate Reg bag
Full breathing control
The second stage features an ergonomic knob and a Dive/Pre-Dive lever to precisely adjust breathing effort and optimize the Venturi effect, reducing free flow when the regulator is left loose in the water. The large dual-material PU purge button, easy to use even with thick gloves, is built into the front shield with a steel ring.
OWS system and side exhaust
The OWS (Optimized Water Strainer) system breaks up the frontal water flow and, thanks to the combined front and side openings, reduces pressure on the diaphragm and the risk of free flow even in currents. The exhaust duct geometry keeps water out of the second stage even in strong side currents and directs bubbles to the sides of the face, keeping your view clear.
Professional first stage
The balanced diaphragm first stage is hot-forged and CNC-machined to reduce weight with high build precision. Its 2 HP and 4 LP ports are ergonomically pre-oriented to connect second stage, octopus, BCD, dry suit, pressure gauge and transmitter with tidy hose routing. The dual-material hose protector prevents kinks and gives an ergonomic curve.
The IT500 OCTO octopus
Easy to spot thanks to its high-visibility yellow front cover, the IT500 OCTO is a reliable, immediately accessible alternate air source, with a 1 m (3.3 ft) braided hose and Venturi adjustment (Dive/Pre-Dive).
