The Importance of Buoyancy Control

Controlling buoyancy is a key component of your diving safety. The physics of floating and sinking are simple concepts, yet achieving practical control of your buoyancy when outfitted with scuba equipment and immersed in water is an entirely other matter. Each change in equipment affects your buoyancy. As your dive equipment grows more complex, the more att...

First Aid Kits: Are you Prepared?

Midwest Scuba Diving—“First Aid Kits: Are You Prepared?” The best way to handle an injury is to prevent it from ever happening, but being prepared to handle an incident is an absolutely essential component of every diver’s emergency action plan. Every diver should be equipped with both the training required to assume a leadership ro...

Seasickness and Scuba

Seasickness and Scuba “Keep your eyes on the horizon.” It’s advice often shared with divers who are looking a little queasy while out on the water. If you’ve tried it, you may be able to attest to the value of that advice. But why does it work? Motion sickness occurs when the brain receives conflicting information about the body&...

Ear Pain Management/Ear Equalizing Tips

Descend a few feet, pinch your nose and breathe out through your nostrils, and you feel that satisfying pop as your ears equalize. Descend a bit further and repeat the process. Equalizing during a descent becomes second nature to many divers, but sometimes, it’s not that simple; congestion and poor execution of equalizing maneuvers can inhibit the proc...

Bubble Trouble: A Look at Hyperbaric Treatment

World Underwater

LEARNING TO BREATHE I’m at the Loves Park Scuba, doing my first scuba training. As a true claustrophobic, I’ll see if it works. Diver Dan starts me off with a “snooba,” a hybrid of snorkeling and scuba, where the swimmer breathes through a mask connected via a long tube to exterior tanks. You can take this off at any point, because th...

Whales

When scuba diving you see a lot of things underwater. Often in the beginning, some of those things can seem pretty intimidating. Being around and sometimes interacting with some of the wildlife that you may run into can be a bit different from what we are used to on land. It is not very common, for most people at least, to run into wild animals that are of ...

Over-the-Counter Medications and Diver Precaution

As divers, we’re taught the perils of alcohol and diving and that drinking and diving don't mix. What about other drugs — specifically the over-the-counter (OTC) variety — and diving? Is the line so clear-cut about OTC medications that are designated by the U.S. Food and Drug Administration as safe for the short-term treatment of ailments...

DIve Medicine Myths

Where would the great pastimes be without their myths and legends? After all, it’s the tall tales and exaggerated stories that keep disbelieving eyes wide and doubting ears open for more. Diving is no different. The myths and misinformation floating around our sport are abundant, partly because divers love to tell stories – the more outlandis...

Hydration

Water, water everywhere, but not a drop to drink? Well, you’d better have a solution to that problem, because hydration can play a key role in a diver’s health and safety. Most divers have heard the “dehydration is bad” lecture, and some are even familiar with how a lack of proper hydration can play a part in dive injuries like de...

Shark fever in the Red Sea

The divers never know what they will meet under water during a dive trip. As the experienced divers use to say, the sea is not an exhibition. You can expect many species, but maybe you won't have any stunning sightings in a week- or you will see something totally unexpected. The Red Sea has a key role since the very first visits of the pioneers of diving. ...

Fin Seeker, A Recent Shipwreck

The story of the fishing charter, Fin Seeker, is the story not only of the capricious and savage power of the Great Lakes but also of the heroism of a charter captain and members of the US Coast Guard rescue teams. Early on a crisp spring morning in 2008 six employees of Nova Communications of Geneva, Illinois arrived at Waukegan’s north harbor. I...
