![]() With their decompression quality index on screen, the diver can query O’Dive’s predictive “what-if” model to determine if-and by how much-they could improve their decompression, by adjusting various factors of the dive, including the fractions of oxygen and helium in their gas mixes, the set point (in the case of a CCR dive), low and high gradient factors (GFs), addition of an extra decompression stop, and/or an adjustment of the length of the last stop. ![]() Until now, taking a post-dive Doppler measurement required a trained technician to take an accurate reading and interpret the results.īut O’Dive goes further. Designed for divers to take their own measurements, the smart, hockey puck-sized Doppler sensor that uploads bubble measurement data to the cloud where it is automatically graded, hopes to provide a breakthrough in Doppler monitoring, one that has been sought for more than 30 years. The device and its associated phone or tablet app purportedly enable a diver to measure the “quality of their decompression” on a scale from zero to 100%, based on an analysis of their dive profile along with the results of the post-dive bubble measurements taken with O’Dive’s subclavian Doppler monitor. It has also been a powerful tool for calibrating decompression tables and algorithms, including the algorithm developed by Karl Huggins for the EDGE.Īzoth Systems Didier Draguiev and divers from Team Alp Tech at the DiveTec show in Switzerland in 2019 Though never a consumer item due to their expense and the expertise required to use them, Doppler monitoring technology has deepened our understanding of decompression sickness (DCS). Spencer introduced the Spencer Precordial Bubble Detector, the first Doppler ultrasonic bubble detection device for divers, which enabled researchers to measure venous gas emboli (VGE) circulating in divers’ blood vessels. In doing so, ORCA created a new approach to managing multilevel dive decompression, which arguably revolutionized sport diving and improved diving safety. ![]() In 1983, ORCA Industries launched the “EDGE” Electronic Dive Guide, the first computational 1 personal dive computer. “Ah, said Arthur, “this is obviously some strange usage of the word ‘safe’ that I wasn’t previously aware of.” Douglas Adams, The Hitchhiker’s Guide to the UniverseĮvery so often, someone invents a paradigm-shifting product that changes the way we view the world, and consequently, the way we behave. “We’re in a small galley cabin in one of the space ships of the Vogon Constructor Fleet,” said Ford. “If I asked you where the hell we were,” said Arthur weakly, “Would I regret it?” Ford stood up.
