How Do You Learn Best? Improve Your Dive Learning Experience

Ever wondered how we learn and how we retain what we learned? Have you noticed that you will retain less than 100% of the material presented? Furthermore, because you zone out, get distracted, or do not comprehend, you are not even cognizant of the things you see and hear during the class. Every time a,

Why Pockets?

Why pockets?

During a dive, clipping gear to D-rings provides easy access to items we use most often. Reels, lights, primary SMB’s and line arrows are good examples of items we use often on a dive.

However, we bring some items “just in case”. Many of these items could present an entanglement issue if stored externally. Pockets are often the best place to store these items.

For example, spare masks, gloves, secondary cutting

2nd Annual Add Helium Expedition Seminar Trip Report

Since last year’s event was a full success, we hosted it again at Dive Tech in Grand Cayman. Conditions were terrific for this time of year. The water temperature was at a balmy 81 degrees all the way down to 400 feet and the air temperature ranging mid 80’s during the day and mid 70’s in the evening. Some of the participants from last year’s event decided to return for another round thus giving the group a nice mix of new and old acquaintances. This year we had Inspirations, rEvos, Megalodons a

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

Blue Holes of Cay Sal Trip Report

Last week some Add Helium members and customers had the pleasure of a weeklong live-aboard aboard the M/V Spree. The destination was the Cay Sal Bank to explore the deep blue holes and walls in this region. Cay Sal is the third largest of the Bahamas Banks, and geographically is just 31 miles northeast of Cuba.

The Pit – Trip Report & Video

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

How Much Is In Your Loop?

Although alluded to in your initial rebreather training, the idea of ‘optimal loop volume’ escapes some divers. Even among advanced rebreather divers, the loop appears to be managing them instead of them managing their loop. They learned to cope, instead of, to control it.

A Letter of Caution from NEDU: Don’t Dive Cold When You Don’t Have to

Many of us may be familiar with the NEDU study:​​​SXLLM​​​ Gerth WA, Ruterbusch VL, Long ET – The Influence of Thermal Exposure on Diver Susceptibility to Decompression Sickness Technical Report. Panama City (FL); Navy Experimental Diving Unit; 2007. Report No: 06-07 http://archive.rubicon-foundation.org/xmlui/bitstream/handle/123456789/5063/NEDU_2007_06.pdf However, some divers have mistaken the data to mean that they should be,
