Yes, I know that is a sick question, but I think it fits more toward the technical side of things even though rec divers can get a cert in it. Having done some ice diving in the past, I wanted to ask my esteemed colleagues here: 1. What kind of equipment and config do you prefer to use...

Questions for the medical people: [list=1] How does one obtain certification in diving medicine? Are there certifications for medical personnel that don't require one to be a MD (i.e. EMT/Ps, Nurses, etc)? Are there courses in diving related topics, such as physiology, that are beyond the...

Curious: Explain or direct me to resource(s) explaining the concept of Fraction of Oxygen in the Breathing Loop versus PPO2 in the loop. I know that Semi Closed rebreathers use teh fraction of oxygen theory and Closed rebreathers use PPO2 as the measure to inject O2 or not to inject O2...

Could someone please explain the ramifications of pressure and tympanoplasty and is this an absolute contraindication to diving. Thanks in advance :)

Curious to know if anyone has used the Suunto computer software (for the vyper, cobra, etc line)? What are it's features, limitations, pros, cons? I am looking for opinions so as to formulate an opinion on whether the $140+ price is worth it. Thanks.
