Polymorphic crystallization inside hoses has recently emerged as a hazard divers should be aware of. Be sure to replace old hoses, limit hoses’ exposure to high temperatures, and follow manufacturers’ maintenance recommendations.

Diver propulsion vehicles are a handy tool that can redefine a diver’s performance. Read more about these vehicles and how to choose one for you.

Communication systems are a niche product for recreational and tech divers. If you’re wondering whether your next diving project might benefit from vox (voice) communication, it’s worth learning a little about the technology, its implementation and use.

Divers generally use lift bags to raise submerged objects to the surface. The lift bag is filled with gas until the object exhibits neutral buoyancy so divers can bring it to the surface with minimal exertion.

Reliable measurement of oxygen is the technology that makes mixed-gas closed-circuit rebreathers (CCRs) possible. The first digital solid-state CCR sensor was made available in Spring 2017, and has greater accuracy and reliability.

Technological advances have greatly changed and improved the dive experience. Learn more about these advances.

Gloves are one of the most overlooked and individualized pieces of dive equipment. When choosing gloves, consider the kind of diving you plan to do and what you expect from your hand protection. When selecting gloves, consider the following factors: thermal protection, fit, dexterity, hazard protection, impact resistance and materials.

Whether for recreation, research, or commercial work, diving puts humans in a fundamentally hazardous environment. Visibility, pressure effects, and sound distortion limit communication between divers and surface teams, making real-time coordination difficult. Response time is critical in emergencies, and delays can be dangerous.

When traveling to dive, consider taking along any of your own gear that’s complex, such as your dive computer, or that enhances your personal comfort or enjoyment, such as your mask or fins.

Oxygen has long been recognized as the primary first aid for scuba diving injuries. In light of compelling evidence in favor of oxygen first aid, one of DAN’s stated missions is to ensure that oxygen first aid equipment and people trained in its use are at every dive site.
