Armadillo Sidemount Harness • Excerpt from ADM Issue 9 • 2002
Text by Brett Hemphill and illustrations by Curt Bowen
Since the earliest side mount divers, such as Woody Jasper, Wes Skiles, and Lamar Hires, began this type of underwater exploration in the United States, many variations have been created and most ideas have been borrowed, tried and accepted or left behind.
CCR Squared • 222M on Dual CCR
by Krzysztof Starnawski
My Blue Hole wall reef admiration is abruptly stopped by the DIVA’s blinking green LED. Hmmmm… it should be RED! I wonder if by mistake I did press oxygen manual addition valve. It’s textbook mistake, unlikely but possible.
Copis Megalodon MCCR
by Mel Clark
A manual CCR (mCCR) differs from the electronic CCR (eCCR) in that it has no computer or solenoid. Maintenance of the PO2 is solely the responsibility of the diver.
CMF - Understanding Constant Mass Flow
by Paul Raymaekers
This editorial is a simplified explanation of the CMF principle, and is only written to assist with the understanding of CMF rebreathers. The author of this article does not accept any responsibility for the use of this information for building or modifying existing rebreathers.
Dead in 7 Minutes - The Importance of a Continuous Flow Oxygen Orifice
Text by Curt Bowen
On any rebreather, oxygen is the main gas that keeps the diver alive. Eliminate the supply of oxygen for a short period of time is all that is needed to end in tragedy.
Jetsam Baby Gas Booster
The most complex and expensive dilemma in remote dive exploration is the capability to fill scuba cylinders on location. Generating the substantial amounts of breathing gas needed for technical diving operations while on site is almost impossible without a cascade of bank cylinders and a large portable compressor.
CCR Sidemount • Stage Sidemount Configuration for Exploration
Text and illustrations by Curt Bowen
Closed circuit rebreathers are definitely the answer to extending what was once a dive that would require multiple cylinder stages, hundreds if not thousands of cubic feet of gas, and multiple set-up dives to explore the furthest reaches of the most famous cave systems or extreme deep wrecks.
Understanding Oxygen Sensors
by Paul Raymaekers
The cell is in reality a current source, not a voltage source, that delivers a current that is relatively independent of the load applied to the sensor, that delivers a current that is almost perfectly proportional to the PPO2 applied to the sensor, but that is heavily influenced by temperature. So without controlling the temperature, or compensating the output for temperature changes, we can not use this sensor body for measuring PPO2 in a diving environment.
