If you plunge into the sea to ogle exotic wildlife, why not stay a while—and get an even closer view? Cave-diving engineer Bill Stone [see "Journey from the Center of the Earth," February 2007] makes that possible with the most user-friendly version yet of a rebreather, a device that recycles your exhaled air, removes carbon dioxide, and adds oxygen. (A scuba device quickly burns through tanks of fresh air.)

On a typical dive, the Poseidon Discovery lets divers stay underwater at least three times as long as scuba gear can, and since you don't exhale into the water, you don't create bubbles or noise that can scare off fish.

Military and advanced divers have used rebreathers for decades, but they're pricey rigs (about $10,000) that require extensive training on how to manually mix gases in case the gear fails. Stone's recreational model automates the safety system with built-in computers that check all components pre-dive, plus two oxygen sensors that monitor the gas mix. If the system spots an air-recycling malfunction, the mouthpiece vibrates and blinks an alert. Just flip its lever to inhale from a small fresh-air tank and return safely to the surface.

Neoprene is a synthetic rubber that's often used to make wetsuits, hence its alternative name "scuba." It's also used in electrical insulation and drum practice pads, but don't let the industrial uses scare you off. Neoprene has become increasing popular as a material to wear on the street (not just in the sea) because many of the qualities that make it great for use in factories, like stain resistance and general durability, make it great for clothing, too.

The fabric is thick and doesn't breathe, making neoprene a perfect addition to your winter wardrobe, and the thickness also allows for creation of structured pieces that look out of this world. The weight of neoprene also means form-fitting skirts and dresses are more forgiving. You'll never run the risk that your bodycon skirt or tight leggings are accidentally a little bit see-through. The material is always opaque, and its resiliency means it doesn't really stretch out. Neoprene also holds photorealistic patterns well, so it's not uncommon to see huge florals or intricate pattens splattered all over a dress or a sweatshirt. Did I also mention it's incredibly comfortable.

My Road to Instructor

My name is Javier Cantellops and I have loved the water since I was born. I have just recently become an Open Water SCUBA Instructor. I have also just landed an amazing job on the paradise island of Maui. This is the story of how I became an Open Water Instructor, the path I took to get to live my dreams, and my perspective on what it takes to do it. My journey was not your average one, that is for sure, but the outcome was nevertheless standard. Meaning if you want it, it can be yours.

I started my diving career as a free diver, free diving wherever I've lived.

I've explored the reefs of the Big Island, been spearfishing in Costa Rica and had always gone scuba diving with my friends along the way just for fun.  I'd never had any classes, just always knew what to do and most importantly what not to do (i.e. don't hold your breath on scuba). That was pretty much all I knew.

After a wild and successful business venture in Costa Rica, and becoming absolutely hooked on diving, I decided, after long thought, that diving was what I wanted to do so we sold the business. I was 32 years old at the time and my son was three and I decided to make a change. So we moved back to the states and staged out of South Carolina, my "hometown", trying to figure out exactly what it was that I was going to do. I had just the barest ideas of what I wanted life to be about. I wanted to be in the water, I wanted to share my passion, I wanted to help people find excitement, I wanted to be an instructor...

I recently left my job as a deep sea diver. I worked for a large company that offers diving services ranging from salvage, underwater demolition, ship repairs, and search and recovery. They are a reputable company and are considered safe and reliable. So much so that they are often contracted by the government. Truth be told, I will miss working for them. The people I worked with were truly the best of the best. But there are only so many unexplainable things you can witness in the deep before you decide to stay out of the ocean forever. Here are some examples of the secrets many divers take to their graves.

The Newtown Creek, a 324 foot tanker vessel, has arrived in South Florida and will soon be sunk in late July as an artificial reef 1 ½ miles off Pompano Beach’s shore. This ship will be one of the biggest contributions to Florida's artificial reef system and one of the most easily accessible major dive sites in the nation. The ship will be the centerpiece of what will become known as Shipwreck Park, surrounded by 16 other existing wrecks covered with marine life. Shipwreck Park will be a unique underwater cultural arts park with rotating underwater art exhibits. The ship will include specific themes, exciting underwater events, artwork and rotating art exhibits to create a unique dive experience for local and international tourists.

This tanker ship which is longer than a football field was sold by the City of New York to The Shipwreck Park, Inc., a private 501 (C)(3) corporation, at a greatly reduced price. Shipwreck Park, Inc. has received sponsorship from the City of Pompano Beach and the Isle Casino Racing Pompano Park for the purchase, towing, cleanup, installation of artworks, and sinking of the ship. The ship was towed from New York to a facility on the Miami River for cleanup and installation of artwork before the sinking.

Pompano Beach artist Dennis MacDonald was hired to create several fun and unique underwater displays, including a casino theme for the ship deck. The art displays will include a swim-through cascade of gigantic dice, great for photo opportunities, as part of the Isle Casino Racing Pompano Park sponsorship.
