Why Now!? Because Sharing Air is NOT the Solution
For many years the standard response to "out of air emergencies" was to "share air" but THAT HAS CHANGED! Read the following articles from leading dive magazines to see WHY that is NO longer the RIGHT answer!

Ask an Expert: Mandatory Redundant Air Systems?
"We must be prepared to solve our own crises, and carrying a redundant air source is the most versatile and safest choice possible, as it creates a fail-safe for air volume as well as correct function of both stages of a regulator."

Air Sharing and Out-of-Air Emergencies by Lynn Laymon
"Sharing air is a safe and feasible alternative when both the donor and recipient are trained, proficient and practiced…and the donor has plenty of air to share. However, this is seldom the case. Many experienced divers would rather risk their lives making a solo emergency ascent than share air with someone they don't know or have little confidence in. And don't expect to find every diver willing to share air with you, especially if he is not your buddy and doesn't know you. Diving accident statistics reveal a sobering fact about cases in which one diver runs out of air and seeks help from another diver. If one diver dies, both divers often die. Sharing air is serious business."

Gearing Up for Going Down
"If you run out of air at depth you'll be glad your buddy's octopus is a high-performance regulator. It is, isn't it? In reality, your buddy is probably low on air too, and his octopus won't do you much good. That's why many deep divers use a completely redundant air source - a pony bottle and regulator or Spare Air."

Solo Diving Facts and Fears by John Francis
"The buddy system can foster a false sense of security. Being a buddy does entail the responsibility to attempt rescue, perhaps at danger to yourself. The co-dependent diver syndrome is, in fact, one of the strongest objections to the buddy system. No one intends it, but the buddy system can foster the dangerous idea that somebody else knows better and will take care of you."

Waiting to Inhale by Robert Rossier
"Regardless of whom you're diving with, real friends may be hard to find when you're out of air at 100 feet."
Scuba Times, May/June 1994
Running on Empty by Bret Gilliam
"Sadly the record of double fatalities for divers engaged in buddy breathing is disproportionately high."
Last but certainly not least: Over 250,000 pieces of life support equipment have been recalled in the last 30 years. In the last 10 years alone, there have been 90,000 pieces of equipment recalled.
