Focus Grand Cayman

Focus Grand Cayman is a weeklong event held every September at Divetech in (you guessed it) Grand Cayman. The event brings together rebreather divers, and underwater photographers for a week of diving and imaging fun.

Like every year, Add Helium was on hand along with representatives from various rebreather manufacturers, including KISS and Hammerhead rebreathers. The weather was fantastic for the entire week with flat calm seas, and the usual 100+ foot of visibility common to the Caymans. The

The Pit is the name for a particular section of cave that is part of the Sistema Dos Ojos caves located in Tulum, Quintana Roo on the Yucatán Peninsula. For years, many dives had occurred in this section of Dos Ojos, until the mid-1990’s when Paul Heinerth observed there was a deep passage that seemed to keep going. In the subsequent years, Paul and Jill Heitheth, along with others made a few exploration dives into the Pit, reaching as far back as 3000 feet, at an average depth of 320 feet, to a

Myth Buster

Myth Buster: Argon, the Superior Dry Suit Inflation Gas?

Staying warm during the dive is not just a matter of comfort. As we have learned from the 2007 NEDU study, it also affects our decompression and, subsequently, our DCS risk. Supplemental insulation provided by dry and wet suits will shift the Lower Critical Temperature (which is the ambient temperature at which heat production responses are initiated) to lower values and thus, delays the onset of core cooling as water tempera
