With some forethought, gear, and preparation, you may still enjoy your dive despite inclement weather conditions.
It was a sunny day at South Florida’s Blue Heron Bridge. Two years had passed since I last dived this location, and I was anticipating a simple excursion to look at the local fish. The dive plan was to make a shore entry and allow the current to take me west down the beach.
The dive light is essential equipment that can benefit all divers on most dives. There are several types of lights with various uses and a few key considerations you should make before purchasing. There is no one-size-fits-all approach to dive lights, so each diver must carefully consider their own goals and needs before deciding which model is most useful.
Divers Alert Network (DAN) maintains a global recompression chamber network, which consists of a database of all hyperbaric chambers with the capability and willingness to treat injured divers.
During the pandemic I asked my partner, David Doubilet, a question: “If you had one full year to dive in one country, what country would it be?” I thought he might need some time to consider, given he has spent five decades documenting the sea for National Geographic.
DAN works diligently to equip divers with the information they need to stay safe both in and out of the water.
