One diver, after a seemingly brief period below the surface, discovers that his gas supply has run perilously low. Another, paralyzed, bobs helplessly on the surface, and when a poorly trained divemaster attempts rescue, things go from bad to worse. Two other divers, fascinated by the bountiful undersea life of the Caribbean, fail to notice that a powerful current is sweeping them rapidly away from their unattended boat.
These are just a few of the true stories you’ll find in Diver Down, most of them involving diver error and resulting in serious injury or death. Each of these tales is accompanied by an in-depth analysis of what went wrong and how you can recognize, avoid, and respond to similar underwater calamities.

It shows you how to prevent tragic mishaps through:
- Inspection and maintenance of primary and secondary diving gear
- Learning and following established safety protocols
- Confirming the training and credentials of diving professionals
