Shopper can i use this with nitrox and can it be used for very cold water diving?
CHRIS G It probably depends on the Nitrox mix you are looking to use. Most modern scuba gear will work with up to EAN40, and manufactures typically don't list that. Beyond EAN40, you definitely need something that specically lists Nitrox up to 100% O2. As for cold water, most second stages work fine in cold water. It's the first stage that typically needs the most consideration when diving in temperatures where freezing may occur. This is an entry-level octopus, designed for emergency air sharing. If you are looking to dive in more extreme conditions, you probably want to make sure your life support gear, exposure protection, and training are all up to the task.
Bill P That depends on the first stage that you are using. This octo is great for both. You want to be sure you have a nitrox ready and sealed first stage.
