NINE: Mind vertical currents



When the current hits a wall or bottom feature, an ascending or descending current is usually formed. This is particularly true in some of the dive sites at Wolf Island. In open circuit you usually compensate for these automatically. Open circuit diving gives you the ability to breathe in or out harder to compensate and this provides time to adjust. This is just not true with Closed Circuit and vertical currents are an issue.
