No Time Like the Present

There’s no substitute for the feeling of being underwater — weightless, focused, and fully immersed in a world few people ever see. Whether you’re enjoying a favorite local spot or exploring a new site far from home, every dive offers something worthwhile: a moment of calm, a connection with nature, a skill refined, or an experience of community with other divers.

Training Turns Incidents Into Inconveniences

I woke up excited for a routine day of diving at my local quarry. While the dive was not in idyllic tropical and clear conditions, I was getting to blow bubbles, which was enough for me.

This dive solidified the importance of the training the author received for calmly dealing with gear failures.

Great Expectations

People expect recreational diving to be an enjoyable experience of adventure and fun. Divers are explorers and retain a sense of optimism regardless of how many dives they have done. While we dive with great expectations, incidents do occur — often when we least expect them.

Beyond the Acrylic

There is a moment in every dive — after the gear is checked, the team gives the final OK, and your body slips below the surface — that everything else fades.
