CONTAMINATED!
Carbon Monoxide Detector for Diving Safety
Carbon Monoxide contamination in breathing gas is more common than you think. Here’s what every diver needs to know.
Silent & Deadly, Why You Need a CO Tester
Carbon monoxide is colourless, odourless, and tasteless. You can't detect it without proper equipment, making it the perfect silent killer underwater. Because it bonds to your Haemoglobin 200 times better than Oxygen, blocking its transport around your body.
Common Sources of Breathing Gas Contamination
Contamination often comes from faulty compressor systems at dive shops. Even well-maintained equipment can produce CO if not properly monitored. For example from external sources such as smoking, exhausts, etc.
How Carbon Monoxide Affects Divers Underwater
CO effects are amplified, by depth. What might cause a simple headache on land can cause unconsciousness underwater - which could have fatal results. And there is no way to escape the exposure once your underwater.
Real Stories from Real Divers
These are actual experiences from divers who encountered CO contamination. Their stories could save your life.
“I started feeling dizzy at 60 feet. My buddy had to drag me up. The dive shop’s compressor intake was too close to the exhaust. I was lucky to survive.”
“Three divers got sick from the same tank. We had no idea until someone tested the air. The CO levels were through the roof. Now I test every tank.”
“My regular dive shop had a contamination issue for weeks before they caught it. How many divers were affected? This is why I bought my own tester.”
