When you need a safe second you tend to need it quickly, so you better be able to see it, and it better be ready to deliver some air. The R195 OCTO does that and much more. The R195 OCTO is a modern second stage design that combines a classic downstream valve with a large diaphragm, functional purge button and VIVA switch for smooth and easy breathing and simple operation. Its robust construction, smooth air delivery and reliability makes the R195 OCTO a sensible safe second stage for all divers and a perfect choice for deco tanks thanks to its extra-long high visibility hose and reversible hose attachment.
The R095 OCTO is an economical second stage featuring classic downstream valve technology that has a well-earned reputation for safety and reliability. Designed to be extremely easy to use in an emergency, the R095 OCTO is pre-tuned to the optimum inhalation volume for safe and uncomplicated use. You never have to worry about control knobs or switches; simply put it in your mouth and breathe. The R095 OCTO comes with a high-visibility yellow purge cover and a 39in/1m yellow hose that makes it that much easier to share air with a buddy in need. It's also a versatile second stage for use on deco tanks, thanks to its reversible hose attachment feature.
TOUGH, RELIABLE, ECONOMICAL
It's the perfect go-anywhere reg for both new divers and veterans who like to keep their diving simple and fun.
For decades the classic downstream piston MK2 has been diving's go-to workhorse first stage. It is reliable, easy to use and won't put too big a dent in your pocketbook, and now it's more versatile than ever.
The new MK2 EVO comes with the patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort -- regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the current MK2.
