The Recreational Diver was chosen with care. We think that „recreational diving“ describes our activity much better than „Sport diving“ as it is for people who want to become divers and not for those who want to try diving. There is a gap to close. A gab in training, that has been weakened by greed. A gap in the training material that is outdated and a gap in the actual training, that is getting easier and easier, to be able to sell it to an even broader range of potential customers. No matter if they have the physical and mental prerequisites for the sport. It is time for a new training system, where quality is more important than quantity and where the individual is more important that the size of the course. Have a good dive.

Oxygen poisoning is, after decompression sickness, the second most important threat to the diver. This book is the first to be entirely devoted to the subject. The author, an acknowledged authority in the field, covers all situations where oxygen or hypertoxic gas mixtures are employed at increased pressures, and reviews many of the factors which may affect the incidence of poisoning.
