How versed are you in buoyancy control? Proper buoyancy is key to a successful dive and it is in part due to weighting. Read more about weighting yourself correctly .

Signaling gear is incredibly useful in a variety of situations — including when the boat leaves without you. Here’s how to purchase signaling gear and what to do.

Oxygen is the standard of care for first aid in dive injuries. You do not need to determine if the injured person is experiencing decompression sickness (DCS), arterial gas embolism (AGE), or nonfatal drowning, as oxygen can be beneficial in all these situations.

Recreational divers are using highly customizable backplate-and-wing BCs to improve their trim and meet their needs in varying conditions.

Dive computers have evolved rapidly since their inception, however, questions arose over the years over their safety. Read more about dive computers.

Breathing gas is incredibly important to divers and just as important as quantity is quality. Do you know the signs of breathing gas contamination?

Sorb, or scrubber, plays a critical role in rebreather diving, as it is responsible for removing carbon dioxide (CO2) from the diver’s breathing gas. Small granules or pellets absorb exhaled CO2 and allow oxygen to pass through. This chemical process allows rebreathers to recycle exhaled air, limiting gas consumption and allowing longer dives. 

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.
