SEAC IT500 Cold-Water Regulator Set
The SEAC IT500 Regulator Set is a high-performance recreational scuba regulator package designed to provide smooth, natural breathing and dependable operation across a wide range of diving conditions.
Combining a balanced diaphragm first stage with an adjustable, balanced second stage and matching IT500 alternate air source, it is particularly well suited to UK, cold-water and drysuit diving.
Balanced Diaphragm First Stage
The IT500 first stage uses a balanced diaphragm design to provide consistent airflow as depth and cylinder pressure change. Its cold-water approval makes it a dependable choice for divers operating in water below 10°C.
The hot-forged and precision-machined body has a durable matt-chrome finish. Pre-oriented ports support clean and practical hose routing for recreational single-cylinder configurations.
Flexible Hose Configuration
The IT500 first stage provides:
- Two high-pressure ports for a pressure gauge or transmitter
- Four low-pressure ports for second stages and inflation hoses
- Pre-oriented ports for practical, streamlined hose routing
- A choice of DIN or INT cylinder connection
Adjustable IT500 Second Stage
The balanced IT500 second stage is designed to provide smooth breathing throughout the dive. An ergonomic adjustment control allows the diver to regulate breathing effort, while the integrated Dive/Pre-Dive control manages the Venturi effect and helps reduce unwanted free flow when entering the water or when the regulator is not being used.
An oversized, flexible purge button remains easy to operate while wearing thick gloves. The exhaust deflector directs bubbles away from the diver’s field of vision and helps reduce interference while breathing.
Matching IT500 Octopus
The included SEAC IT500 Octopus provides a clearly identifiable alternate air source for recreational buddy diving. Its matching design delivers dependable breathing performance and completes the regulator’s single-cylinder configuration.
Cold-Water Approved
The SEAC IT500 is approved for cold-water use and complies with the applicable EN 250 standard. This makes it a strong option for year-round UK diving, inland dive sites, drysuit diving and other environments where water temperatures may fall below 10°C.
Protective Regulator Bag Included
The complete set is supplied with a semi-rigid SEAC Mate regulator bag. Its padded construction protects the regulator during storage and transport while keeping the complete set organised between dives.
