“This world is strange” and the passing year has been strange. It has given us all a hard time. Local diving has become fashionable. Thanks to this, we can spend less time commuting and more time finding new water reservoirs, not located in thousands, but several dozen kilometers from our home. Christmas is coming. Contact with loved ones may be difficult, and it is always a time of quiet family celebration. Let us do everything we can to take a break from the ills of this world, take a distance and fill ourselves with optimism and positive emotions. Let the New Year be a good year, healthy, full of exceptional events. As a magazine, we are entering 2021 with specific plans. Follow us on social media. We are speeding up the publication of our bimonthly. Now we will try to make you have it in front of your eyes and in your hands at the end of the first month of release. So the end of January 2021, then the end of March, May, etc. The current issue has a lot to offer. Beautiful photos and a light pen of the authors will make you dive with us virtually. First we have Honduras for you. Finally, a very practical text about buoys. Inside, inter alia, an interview with the outstanding photographer Henley Spiers, whose photo adorns our cover, and as a curiosity – "pudding" from Lake Werbellinsee in Germany. And what exactly is this zooplankton. Explained and shown. I cordially invite you to come inside. All we have is at your disposal. You can now order a subscription for 2021. From January, the price for a copy is PLN 25 plus shipping. We also have a very nice calendar with beautiful photos. First come first served. Until stocks last. And your personal support in the form of a donation for our editorial office is appreciated.

Gulf Islands In Search of the lost sand

On Utila you cannot do without decent sandals or flip-flops. A bit of sand, which was artificially brought here, can be found only on the hotel Bando Beach. Apart from this, the coast is a range of rough, dark rocks. Those rocks were feared by the captains of Spanish galleons, exporting the treasures of the New World to Europe. But on the other hand, pirates liked the area very much. The Gulf Islands were the hideout of the shore, following colourful fish or a lonely turtle. In the after-

that hides underwater: a coral reef stretching on the edge of the continental shelf of Central America, which on the northern side of the archipelago falls steeply into the abyss of the Cayman Trough. A huge variety of marine habitats makes underwater off the coast of the Gulf Islands extremely rich, with more than 95% of the species living in the Caribbean Sea. We get to know a small piece of it, swimming with a mask and a tube off the southern shores of Utila. We enter the sea in the bay on the west side of the town, where getting through the rocks is facilitated by piers. We immerse ourselves in the turquoise, and after a while we flow over the edge of the reef. It falls not so deeply as on the northern side of the island, but very steeply, almost vertically. Here and there are elk's antlers-like corals of the species acropora palmata, with a lot of colourful parrotfishes spinning, and where smaller sergeant majors are glittering like gold flakes. Suddenly, somewhere down from behind the reef, a stingray emerges. We hang over it motionless and watch as it flows slowly through a blue procession, intersected by rays of the sun. We will remember this meeting for a very long time.

The most peculiar and some of the most beautiful inhabitants of Utila, however, hide not on reefs, but on land. They are quite shy and avoid contact with people, but there is a place where you can almost always meet them. From the town centre we climb up the street towards Stuart's Hill, one of only two hills on the island, and turn left into a large Caribbean-style wooden house hidden among lush greenery. On the lawn in front of the building we see several palm thatch huts made of metal mesh. And in them the most important tenants – iguanas of the species ctenosaura bakeri. These reptiles are critically endangered. They are found only on Utila Island (which is 6 kilometers wide and 11 kilometers long), and they dig nests on a few narrow beaches on the northern side of the island. The Iguana Station employees and volunteers collect eggs and move them to a facility where the young hatch in incubators. Then they take care of the lizards until they grow up enough to cope in the natural environment.

of Utila, which quickly pass into a low mangrove forest. We go through the tangle of roots. No trace of any path, but our guide knows every angle here. Unfortunately, poachers are equally confident – meat and eggs of iguanas are still a delicacy for some islanders. They are not deterred by mosquitoes, nor by crabs sneaking out from under our feet, nor by mud. Although it is the end of the dry season, every few steps we fall into a sticky goo, sometimes all the way to the knees. Suddenly, an invigorating turquoise can be seen among the thickets. We come out on a narrow strip of light sand, surrounding the shallow Rock Harbour Bay. Apart from our group, there is no one, tourists from the town do not come here. This is the perfect place to release iguanas. We watch as the guide carefully takes them out and puts them on the ground. We observe from a distance so as not to frighten the animals unnecessarily. They look around for a moment, probably bewil-

backpackers travelling through Central America take their first steps in the underwater world on this island: the conditions are safe and pleasant, and the prices of the courses are reportedly among the lowest in the world. Our goal is the linked Jewel Cay and Pigeon Cay, two of a chain of coral islets at the southwestern tip of Utila. Interestingly, it is here that the oldest settlement on the island is located, founded in the first half of the 19th century by newcomers from the Cayman Islands. Today the islets themselves are practically invisible. They are tightly built up with houses and huts, and the structures supported on stilts spread over the sea that washes the rocky shore. There are no cars, no scooters, but everyone has a boat. A real water world. The trainees stay on Jewel Cay, we get into the canoes and row further west, first through the dark saffron depth of the strait, then along the shores of the two islets. Finally, it appears to our eyes: the Caribbean kitsch painted with the turquoise sea, the white of the beach, the green of palm plumes, flecked with red starfish lying in the shallow water. Water Cay is a triangle about two hundred, maybe three hundred meters long, only a few dozen wide, but it is not difficult to forget about the whole big world here. We lie down on the sand, squint our eyes, and bask like the endemic iguanas that have finally found their island.

But… anyway you wrote to me that you liked our Perfect Diver Magazine, can you tell me more? As a photographer, the first thing I do when picking up a magazine or book is look at the pictures.

perfectdiver No. 6(12)/2020

Mahatma Gandhi was right in saying that: Freedom is a state of mind. We are sailing towards the island of Solta, the thirteenth largest Croatian island, situated in the Adriatic Sea. It is surrounded by small emerald coves and picturesque pebbly beaches covered with pine trees. These trees not only diversify the landscape, but also shelter numerous creatures, including cicadas, which are considered the loudest insects in the world. Adult males, wanting to attract a partner, emit noises that exceed 120 dB. They are so loud that they drown out the engines of yachts entering the port. The captain is mooring the boat near the island, after forty minutes we got to the first dive site, famous for a small but very beautiful underwater cave with a dry chamber inside. I put on my thermal underwear, put on a drysuit, and it is August. The air temperature exceeds 35°C, and the water temperature varies between 23°C and 24°C. Most people dive in 5 mm wetsuits, but I cool down quickly in the water, so for thermal comfort I took a drysuit and a hood. I put the regulator in my mouth, press the bleed button on the inflator and plunge into the sun-bathed Adriatic Sea. I slowly penetrate into another world, full of magic, silence and peace. A world that hides a lot of secrets.Sometimes it is capricious and we have to fight the currents, other times it is gentle, calm, ready to tell us its story... I drop slowly, like a bird descending to land and watching everything from above. The view is phenomenal, it exceeds 40 m, I look down and see the border where the light blue turns into the dark blue. I swim along a sloping rock wall overgrown with a variety of corals, sponges of irregular shapes and intense colours. They usually take the form of elongated trumpets and grow out of the ground. In numerous rock depressions, navy blue and red bristle worms hide. They have an oblong shape, resemble hairy caterpillars, and their cylindrical bodies consist of more than a hundred segments. They are covered with bristles that sting heavily.

I have dived in Croatia many times and I discover it anew each time.

After the dive, we head to Maslinica, a small town on the island of Solta. A real paradise bathed in the afternoon sun. We enter the marina, which seems to be small, but both small dive boats and beautiful luxury yachts covered with chrome and varnished wood moor there. The marina is flowery, pink and white bougainvillea attract colourful butterflies, including swallowtails, one of the most beautiful representatives of this species. The town looks like a fairy tale. Low buildings made of light stone, charming cafes on the seafront, offering not only delicious coffee, but also ice cream that tastes best with friends. The restaurateurs invite you to try fresh seafood, fish and oven-baked pizza served with olive oil and herbs. Small shops, or rather galleries, offer handicrafts, paintings and jewelery that tourists eagerly buy. We have our favorite cafe in Maselnica at the end of the headland overlooking the sea, where we always relax, enjoy delicious cappuccino and ice cream, and then enjoy swimming in the sea and sun. After the surface break, we sail out for the second dive. The dive site is about 15 minutes from the island of Solta. We stop at a rocky island with a small, green lighthouse in the

Such depth gives us a lot of time to explore the wreck, but also sometimes, when the weather is windy, the waves occur, and the entire site is not suitable for diving for safety reasons. This is a great place for macro-photographers because the wreck is overgrown with various types of sponges and lush vegetation which is home to many species of nudibranchs, including Hyspelodoris picta in the first place. On the wreck you can also meet lobsters, Scyllarides and sometimes barracudas. This place can awaken your passion for wreck diving. Personally, I like diving on wrecks mainly because they crate an artificial reef. They are a new place to be settled by marine organisms, which can colonize any available surface in an unusual and very fast way.

Now it's time for a trip to the top of Tavolara, the island where I previously dived. After all, man does not live by diving alone. However, all in all, it’ll be just another short surface break :)

Lake Werbellin is a ribbon lake which was formed during the last glacial period. Thawing waters formed a canal, which was continuously deepened along with the increasing pressure of the water trapped under the glacier. Uneven pressure led

There is a dozen diving sites around the lake, marked with appropriate signs. The signs are marked with the spot number, name of the dive site and maximum depth. It's enough to give this number to the emergency services in the case of a diving accident. Rescue will arrive from the water and air in just several minutes. Everything is perfectly organized. The most popular diving site is the “Dornsbuchwreck”. This is a more than 100-years-old, 40 meter-long wooden barge located not far from the shore. It sits at a depth of 35–38 m. There are many more such barges in the lake. However, in this article I would like to present a much less popular spot.

Have you ever wondered what a professional diver sees under water and how is it transmitted to the surface?

nlike recreational diving, a diver working under water gives an image of what he sees on the surface to the person operating the video panel.

Several companies in the world specialize in the production of this type of equipment. In the United States, the most recognizable brand is AMRON International. One of the most popular video systems for divers is the 3400 system with a 15” monitor and the ability to record in HD quality. Of course, this also depends on the camera used. On the European market, several companies associated with the production of equipment for the needs of professional diving, also produce such systems. The company Ocean-Tech Sp. z o.o with its innovative solution UV2 (Underwater Video System UV2).

The Video UV2 system is dedicated to two divers. Solution created by the team of Ocean-Techto company. A fully functional video system that uses the latest electronics and introduces facilities compared to other video systems companies. Video recording directly after pressing the REC button on the desktop, another improvement is the power supply in the event of a power failure, as well as the ability to connect the video source to an additional TV or monitor with an analog input. The audio input, after connecting the underwater communication, allows you to record sound together with the image. New features make the UV2 the most advanced video system on the market. The UV2 model is equipped with a 12 V gel battery with protection against deep discharge as standard.The whole system is closed in a durable, black plastic case with all controls and connections located on the front panel, which makes it easy to use.

Water is a natural magnet for divers. An element that literally drags you into its depths. I've always wondered what is so special about water that it makes so many people want to risk their lives, spend money, waste their time at the cost of family time in order to spend some time in these depths, even if it’s just for a moment.

DAN Europe is also working on new insurance products, with the intent to meet the evolving needs of the diving community—particularly now with the emphasis on local diving, and reflecting the ever-changing situation of the market. The insurance will supplement divers’ national healthcare system coverages, which generally do not provide the specialized knowledge and assistance required for diving injuries or fully cover hyperbaric therapy. Details of the new plan will be announced soon. The new insurance product will complement DAN Europe’s basic 25€ membership package, which provides 24/7 access to the DAN hotline and diving medical advice, access to MyDAN, and the App (Google Play, iOs). In addition, the DAN Europe team is planning to support and participate in local diving projects of their own, following a recent successful citizen science project at the Pescara Springs Natural Reserve located a little more than a half an hour drive from one of DAN Europe's operations offices located in Central Italy. There the team joined marine biologists to survey the autochthonous freshwater crayfish living in Springs.

●● Ascending to the surface in the open sea, when the current prevent your from returning to the wreck with the shot line. Under these circumstances, deploying a buoy as fast as possible, so that the observer from the boat can see it before the diver is too far away, is essential for the diver’s safety. The observer may mark the direction in which the diver is drifting away, come after them or send a RIB. The diver (or a team) completes decompression in open water and is drifting away from the boat not only due to the current, but also due to the wind (discussed in more detail later on in the article). When the observer reaches the buoy that is drifting away, they may “ask” the diver underwater whether they are all right. It can be done by slightly tensioning the line, at the end of which there is a spool or a reel held by the diver, and then giving two distinct tugs (“are you ok?”). The diver then also gives the line two tugs, which means that everything is all right. Another possible answer is a series of fast tugs that means “I need help!”. In complex decompression diving, such situations are always taken into consideration and the support team waiting on the boat is ready to quickly descend to assist the diver. The details of such procedures are discussed beforehand and practiced repeatedly. ●● Deploying a buoy with a message. Almost every diver Photo Mariusz Czajka

Under some circumstances, buoy deployment alone is not enough and the observer needs additional information. Usually, it is the case with more complex technical diving that require a long decompression. Below, you will find typical examples of buoy usage and the situations requiring it.

to the surface.

●● Deployment of a buoy without a line. Deploying your buoy like this may replace an underwater wetnote with the note: “no object at the bottom”. Such a buoy is easily recognizable, as it lies horizontally on the surface. It is fished out by the diving boat’s crew. Buoys are often used in such a manner in wreck diving. Once a possible wreck site is identified, one team descends to the bottom and informs the other divers whether the wreck they are looking for lies at the bottom. Similarly, a buoy attached “rigidly” to the wreck means “we have it !”. Of course, nothing will prevent you from deploying a buoy with a tether line and attaching an underwater wetnote with appropriate information to it if there is no object underwater. 2. Static buoy usage Static usage means that, when a buoy reaches the surface, you attach the line of the buoy to an underwater object. When to do so and why? ●● Securing your practice area. When practicing in a water body, where they may be other people on the surface (such as swimmers, but also drivers of water scooters and other vessels), it is good practice to mark the practice area, e.g. with four Photo Francisca Isadora Abuter Grebe

buoys forming a square. After your first dive, such marking will also help you quickly find the practice area again. One option is to use several buoys to secure a practice area

3. Using a buoy on the surface ●● Location signaling – call for help. Such use of the buoy may be required, for example, when you are diving in the current while on safari in Egypt and for some reason you cannot ascend at the planned boat pick-up site. The wind drowns out your voice and even the slightest waves effectively reduce the chances of being seen on the water surface. What you can do is dynamically move your firmly inflated buoy as fast as possible, treating it as an extension of your arms, to signal for help. A DSMB is particularly well-suited to that task. If you start signaling too late, it may prove ineffective – unfortunately, a lot of divers experienced it firsthand, when they were carried with the current to the open sea. ●● Location marking – air searches.

cent. Not everyone is prepared for ascending in open water and even experienced divers may have a bad day. You should deploy a buoy to assist with your ascent each time you feel that it will make you feel more comfortable, and consequently safer in the last phase of diving. You should also pay attention to the needs and well-being of your less experienced buddies. Do not wait until such a person is no longer stable in the water – ascend together, while using the line of the deployed buoy as a point of reference.

The diving buoy is usually called SMB or DSMB. Sometimes it is also called a bag or... sausage 

6. Classification of diving buoys Color – buoys are available in various colors; those used at sea usually have an emergency color – orange or yellow. There is no one rule for this. It is essential that the buoy has a color that is easy to spot from afar and in any weather conditions (certain colors may be less visible in full sunlight). Types of diving buoys – the main classification is based on the shape and inflation method. Buoys can divided by inflation method into closed, semi-closed (fluted) and open.

Most buoys are equipped with a relief valve that is almost identical to the valve in wings and jackets. caution! Before diving, check how the valve in your buoy works by conducting a dry run and inflating it several times. Some inflation valves are very intuitive, but others require pressing a certain element to inflate the buoy. Some valves also have a special valve lock nut. It’s best to check how it works on the surface to avoid any surprises underwater. Photo Bartłomiej Trzciński

8. Buoy deployment technique A buoy floats to the surface when it is inflated with gas. It is attached to the spool or reel with a line. This means that the diver needs to stay focused, as they operate a tool that may rapidly change their buoyancy, but also they may get entangled in the line. Such a configuration requires a very precise buoy deployment technique, which is mastered in small steps. Interestingly, many divers use entirely different techniques. They use different inflation methods and amounts of gas and operate the spool or reel differently. Bearing in mind how important and necessary the buoy is for a diver, I recommend to learn how to use it from an instructor. And I strongly encourage instructors to introduce buoy deployment exercises as early as during the basic course. It is worth practicing buoys deployment, regardless of your Photo Bartłomiej Trzciński

It is not ideal to use large-diameter buoys (a DSMB) as primary buoys for fast communication. Such buoys are much more susceptible to strong gusts of wind at the water surface than buoys with smaller diameters. When blown by the wind, such large buoys haul the diver to the surface.

How you actually use a buoy depends solely on what you need and what was agreed with the team. Photo Tomasz Płociński
