Product Information
The Seac Regulator Package puts a complete first-stage-to-octopus setup together in one order: the Seac MX100 regulator, the Seac IT300 octopus, and the Seac Mate regulator bag to carry them in. The MX100 is a balanced diaphragm regulator built for both new and experienced divers, with a heat exchange system in the first stage for cold water diving and an environmentally isolated design that keeps airflow steady as tank pressure changes. A removable stainless steel valve seat makes upkeep easier, and the venturi control lets you fine-tune airflow to your liking. Pick INT or DIN when you order so the first stage matches your tank valve.
The IT300 octopus is your backup regulator, connected with a 1m braided lining hose for durability and flex. A simple switch adjusts the venturi effect between Dive and Pre Dive modes, and the whole unit is made in Italy and certified to CE EN 250-2014. It's lightweight and built to work smoothly alongside the MX100 in an out-of-air situation.
The Seac Mate regulator bag rounds out the package, giving the MX100 and IT300 a dedicated home between dives. It's made of 600D Polyester and measures Ø12.8" x 3.9", enough room to keep both regulators organized and protected in your dive bag or on the boat.
