"Let's spend the time given to us to have the impression that it is flowing, not that it has sailed away." And the diver knows what it means to swim against the tide, in drift and peace. What do we have in the current issue for you? Just click and orient yourself. Indonesia is a huge country. There is a lot of salt water and islands in it. Two completely different looks and two completely different places of paradise. At least those who were there say so. Do you have your opinion? Have you ever been there? Maybe it's time for plans? Mateusz Popek believes that we should enrich the Magazine with the "reviews" heading. Very good idea. See what we have as our first review. Maybe you will write yours about the book you read? (Redakcja@perfectdiver.com) We support activities related to stopping illegal shark finning. We have strong text and photos, and finally QR codes to sign the appropriate petition, if you think it's worth it. We bring pike to you with Agata Turowicz's feather. This is an interesting animal that also flows into the Baltic Sea. I can't write about everything in the editorial, but at the end we have another article by Wojtek A. Filip about aspects related to the proper matching and use of diving equipment. What about this time? Check it out yourself! You click and dive virtually. Safe and interesting. We publish for you, your family and friends. Tell them about Perfect Diver Magazine. The online version is free, but you can help us by donating at least a symbolic zloty (1 euro) . Just click. I invite you cordially!

hen we say Togian, probably not many people will know what we are talking about. When we say Su-

lawesi, most will probably know. When we answer Indonesia, almost everyone will know. Yes, the Togian Islands are part of the Indonesian Central Sulawesi, the island of Sulawesi. However, tourism and diving have not yet settled here on a massive scale, thanks to which there is wonderful peace. I dived in Togian three times, made about 80 dives, and I have never met any other diver here than our group. But this idyll will definitely not last forever... Geography The Togian Islands lie just below the equator in the Gulf of Tomini and are protected on three sides by the island of Sulawesi, making the sea very calm and the waves are rare.

the next day a supply ship brings it to you. Meals are always cooked directly at the resort, and the food is more than great, everything is fresh. There is no centrally installed electricity. The resorts usually use generators and only for a few hours in the evening so that tourists can charge their cameras, lighting and hit their bungalows. There is no frozen food. Every morning, a boat leaves the resort and brings fresh fish or squid, which is processed and served immediately. As the appetizer you get vegetables and, of course, rice. Everything natural, without preservatives and other chemicals that we eat in Europe almost every day. Of course, there is also a lot of fresh fruit. If, for example, you fancy a coconut, you just ask a local and he climbs the palm for you and gets one. Always after returning home I remember this delicious food with a tear in my eye for a long time. On the islands, you won't find an ATM or payment terminal, so you need to get enough cash in the local currency (Indonesian Rupiah) earlier. It is worth remembering that dollars and euros cannot be exchanged here at all. There is no internet access and there is usually no signal for mobile phones, it is amazing relaxation when you use the phone only as an alarm clock throughout your stay and you do not mind the continuous "sound" of your own phone. Diving Togian is said to be the only place in the world where you can dive on the atoll and coral reef in one place. You don't often see big fish here, but there is definitely something to look at. The variety of species is unbelievable. Several endemic species have been discovered here. If you look closely, you will find several species of nudibranch during each dive. I personally saw at least 30 here. Of course, there is an inexhaustible number of small coral fish, many different species Accommodation There are no large hotels on the islands, you only live in

Diving in the place where dynamite was used for fishing is also very interesting. Stripes of intouched reef alternate with strips of completely destroyed corals. Fortunately, we find new life in them. From the Waleakodi and Malenga islands, we often sail to one of the reefs, north of the islands. These reefs have no names but are simply numbered as reefs I-VI. Here there are both shallow coral gardens and steep walls falling to a depth of about 45 meters. Larger fish can be found here, especially blackfin sharks. From other animals we often encountered rays and venomous sea snakes. Diving on the island of UnaUna is also interesting. It is located a bit further from other islands. The most interesting is the place called Apollo. Barracuda accumulate here, forming a flock of several thousand and circling at a depth of 45 to 20 meters. Diving in this flock is one of my greatest diving experiences. How do the locals dive? They've been doing it for years, but a little differently than what we're used to. They have a small compressor placed on a wooden boat, a hose attached to it, which the diver

snorkling without fins is allowed to avoid damaging the delicate jellyfish. The lake is still freely accessible (no fee). It is not known how long, because local authorities have invested and since last year two new piers have been built, one at the sea and one on the lake. An access road was invested and construction of the building started. In the future, you can probably expect that the entrance will be paid. On land On the island of Malenge you can visit the large bat cave, which is located a few hundred meters from the coast in the jungle. Everyone who returns from it smells “beautifully”. An interesting inhabitant of the islands is the palm crab, which is the largest ground crustacean, with a span of up to 2 meters. Because it has very tasty meat, it was often hunted. Today it is protected, and locals like to observe it from hidden. Locals can set up a hideout so you can see it, but you still need luck. A visit to the Gypsy sea settlement connected with the larger island by a 2.5 km bridge is also an experience. Originally it was entirely wooden. Apparently in 2014, when it was carrying the weight of a 100-kilo European, it could not bear it. Locals have found that wood is probably not the best material for tourism development. Thus, in the second half of 2014, local authorities built a new, mainly concrete bridge that could withstand the weight of "normal" people. Locals should be really grateful to me ;)

What connects people around the world is the need to feel happiness and joy. Happiness is nothing but being grateful. A grateful man is one who loves life, appreciates and can enjoy small things.

"Feeling gratitude allows you to grow and develop. Gratitude brings joy and a smile in your life and the lives of those around you" – Eileen Caddy.

n April 5, I participated in a global meditation for healing our planet, animals and people. At the same

time, millions of people meditated all over the world. Collective meditations can do a lot good, as confirmed by scientists.

meditation was not for me and I should come to terms with it. However, I remember exactly when everything changed and I finally reached a state of deep relaxation. It had nothing in common with the lotus position or stillness that I had tried to practice until then. It was the day I started diving... I did not immediately understand this, as a beginner diver I was more focused on myself and diving equipment than on what was happening around me and inside me. Over time, when I gained experience, the big blue consumed me completely and I do not mean deep depths because I am a recreational diver. It is under the water surface I understood what it means to control my own mind breathing and focusing on what is happening here and now. That feeling was so poignant and beautiful that I wanted to experience it also on the surface. My imagination helped me, thanks to it I was able to meditate at a place where I felt happy, once it was the tiny island of Yeben on Raja Ampat, and other times the ocean floor. I imagined that I was lying on the beach and around me there is a powerful silence, but not complete, because I heard the sounds of nature, birds and waves overflowing on the water surface. And although I felt what was happening around me, I was not in the center of events, I focused on my breath, I listened to its sound. Each of us is accustomed to acting, thinking and living on the run, but the essence of At the beginning, the meditation was very difficult for

The life of Gili Trwangan focuses on the beach, which is extremely beautiful, long, wide with white coral sand. This is where tourists gather and the best events take place. Along the shoreline are also most restaurants, cafes, souvenir shops to which we enter without shoes so as not to put sand inside. There is also a mosque from which several times a day you can hear prayers. A little further away are diving centers, more and less luxurious hotels and guest houses.

Dives off the coast of the Gili Islands are not the most beautiful, many people can feel disappointed, after being tempted to dive by the beautiful views of the surface. Once nearby, the reefs were teeming with life, they were beautiful and colourful and healthy. Today, their fossilised remains are washed ashore. Climate warming, combined with the destructive activities of people have contributed to their dying. People hurted the reefs most when they tried to maximise their catches by using homemade bombs and the cyanide. These two methods not only killed fish, but also irreversibly damaged the coral reef and sea habitats. Today, this type of practice is prohibited, but unfortunately you cannot undo the events of the past. You can only try to fix what is destroyed, where possible. In 2020 the Organisation Gili Eco Trust was established, which aims to protect the coral reefs and marine life. From the moment the organisation was established, the situation began to improve slightly, first of all it focused on education, that is why the locals were involved to protect the marine habitats. The reef was planted. GET expanded its activities by many other projects, such as sustainable tourism, recycling, garbage selection, which began to bring noticeable results. Dives off the coast of the Gili Islands, despite the destroyed reefs, is still very popular among tourists. They usually choose one or two dive days. The diving season lasts almost all year. During diving you can come across a large group of turtles that swim near the shore in search of seagrass. On the island there is a warm, tropical climate with dry (May-October) and rainy season (November – April). Currently, the climate has changed all over the world, therefore I would not be attached to the above division. And although I imagined this place differently when it was only in the sphere of my dreams, I have fallen in love with it including all its imperfections.

dreds of thousands of artifacts. Among others, 250,000 lead missiles, 24 guns and two anchors. In addition, the ship's bell and aÂ lot of personal and everyday items. By analyzing these objects and where they were found, the researchers found that they had found the shipwreck of Queen Anne's Revenge, which was the scene of Blackbeard's last moments. The monuments went to the North Carolina Maritime Museum in Beaufort, where they can be admired. In this way, Blackbeard's story came full circle. From England, across the Caribbean Sea, to the North Carolina Museum and on TV screens. He probably did not think that almost 300 years after his death they would tell about him that he would become one of the characters in the film Pirates of the Caribbean. Was that his goal? To be remembered? Or maybe he was driven by more hedonistic motives, like quick money, rum and women, and he went down in history quite by accident? Unfortunately, we will not know the answers to these questions, because only he could answer them.

My April was somewhat different in terms of diving and I guess it was also the case with many of you. First, together with Mark Eyllatt, I went searching for the wreck of HMS Victoria* off the coast of Lebanon; then I joined Sheck Exley to start exploring the dark pits in Florida.** At least it wasn’t rocking that much there.

I was sure it wouldn’t, as Sheck hated the bobbing too. So when the telephone rang, I put my book away rather reluctantly. After all, how interesting could it be, since we’re all stuck at home? It was Wojtek, I mean the editor-in-chief, to remind me it’s time to submit something for the next issue. Right. I’ve been pondering this for some time now and since I knew a thing or two about underground caves, I somehow focused on this topic. And I came to the conclusion that

It has long been known that dolphins altruistically help each other, push the weakened member of the herd to the surface, just like they do with a newborn calf so that it can take a first breath on the surface.

New Zealand, on the other hand, a lone Moko dolphin saved two dwarf sperm whales that were stuck on Mahia Beach. Bottlenose dolphins responded to the acoustic call of the sperm whales, approached the whales and led them 200 yards along the shoreline, between the shallows, through a channel into the open sea. Looking for the answer to the question of whether dolphins cling to people in a special way and want to protect them, it is worth asking another question: Were there cases when dolphins did not help people? Or maybe they even threatened their safety? Marine mammals researcher Toni Frohoff, the director of Terramar Research in California, described the incident in which dolphins with which she swam in the sea suddenly escaped when a shark appeared and left her alone. In turn, in 2007 a man who fell into the sea in the Ukrainian part of the Black Sea, was attacked by a group of bottlenose dolphins. He lost consciousness and almost drowned. There is no doubt that dolphins are interesting to people and seem to be looking for human contact. But should such social contacts be considered friendly? Of 29 well-researched lone dolphins with frequent contact with people, 13 of them showed "inappropriate, often aggressive, sexual behavior towards people." Many of these dolphins used to pull people into the sea, preventing them from returning to shore, and even pressing them to the bottom. Two-thirds of the 29 dolphins showed such dangerous behaviour towards people that they caused spleen ruptures, broken ribs, loss of consciousness, and in one case even the death of a tourist. In 1994, the Brazilian dolphin Tião managed to send 28 people to the hospital during its visits to the beach, before eventually killing the swimmer João Paulo Moreira (who was probably drunk and also aggressive towards Tião).

EAP â&#x20AC;&#x201C; Emergency Assistance Plan Emergency plans - what is this for?

The Emergency Assistance Plan (EAP) or emergency plan is aÂ prerequisite for successfully rescuing an injured diver. It includes immediate first aid on site and emergency treatment, as well as the fastest transport to the nearest and most appropriate medical facility. The responsibility for reacting to the EAP lies with the local dive operator.

the fact that fins can be sold at 25 times higher prices than shark meat and require a small storage area, only these are retained while the rest of the animal is thrown back into the sea. The animal sinks to the bottom because it can no longer swim and dies from suffocation or as a victim of other predators. It's a terrible waste of marine life. It contradicts credible resource assessments and effective shark conservation measures because neither the number of animals killed or species caught is reported for such IUU fishing (illegal, unreported and unmanaged). In this regard, many nations and some Regional Fisheries Organizations (RFMOs) have introduced laws to prevent this destructive but highly profitable practice of finning at sea, requiring all sharks to be landed with "fins naturally attached" to their bodies. Only then can authorities verify in the port that no finning has actually taken place and whether the number of fins on board really reflects the number of sharks caught by the vessel. This FNA policy is mandatory on board of all vessels flying the flag of the EU and in all European waters since 2013. This was a significant improvement over the previous regulation, but still allows the fins to be cut off in port and traded throughout Europe and the EU, thus meeting Asia's high demand for shark fin soup. Furthermore, maritime controls are performed too rarely and often almost impossible to carry out, which results in overall low oversight of enforcement even in EU waters. During sea transhipment of fins to other vessels, which are then unloaded in countries without FNA policy in force, e.g. Namibia, it also provides concealment to circumvent this regulation. Illegally obtained fins are difficult to identify, and species identification based on isolated fins often requires time-consuming and costly analysis. That is why trading in fins and endangered species is an However, the biggest threat to their survival is the prac-

Only a small part of environmentalists' research concerns changes in the environment caused by human activities. From this perspective, the term "ecological toilet paper" (and almost everything has already been called "ecological") is not the best one, although it is probably already too late and ecology in the social sense of the term will remain equivalent to environmental protection. Anyway, even biologists will most likely have to endure such word clusters, risking at least a misunderstanding on their own when talking about "environmentally friendly" products instead of "organic products". I must be sincere, however, and add that there were many definitions of ecology in history – and thus some homework for you: check what is hidden under the term "ecology" in the encyclopedia – it can be Wikipedia, and for those who like contact with the printed word, check heavy volumes in hard cover.

Finally, some facts about the mallards. They obtain food, mainly plants, by collecting it from the water surface. They do not belong to eager divers, although they can dive, limiting themselves at most to immersing the head and neck, leaving the ramp raised above the water – just like e.g. swans do. The mallard can fly quite well. It can reach up to 90 km/h and usually does not rise too high. There was a meeting of a cruise plane with a mallard reported at the height of more than 6 thousand metres. However, it spends more time (except flights) on the water. Sometimes quite cold water, including ice. How is it that duck's legs are not freezing then? The secret lies in counter-current heat exchangers, which function not only in mallards, but in most birds, as well as fish. The thing is, the arteries and veins are located close to each other, so the warm arterial blood flowing to the feet heats the returning one. The temperature difference can sometimes be over 30 degrees. Encountering mallards – the ancestors of domestic ducks – by the water, remember to congratulate them on their evolutionary success!

Wetsuit Selecting the type and size

Text margita Ślizowska

Photos wiktor zdrojewski

Before you go for snorkeling, it is worth buying a neoprene wetsuit. Due to the variety of functions that a wetsuit fulfills - it might be useful to everyone.

1. A wetsuit provides thermal protection (as we get cold in water about 25 times faster)

to 2.5–3 mm thick. The one which I always strongly recommend is a "lycra costume" covering most of the body: the so-called skin. If someone gets cold quickly or intends to snorkel in very cold water – I recommend a diving wetsuit (3–7 mm), which can be applied in layers. To sum up, when choosing a wetsuit (snorkeling or diving) we should pay attention to: the thickness and elasticity of neoprene, the type of inner lining, cuffs, the way of joining

The wetsuit should be selected depending on its thickness and what it is supposed to cover. In popular sports

that have zips (at wrists, ankles, neck). When putting them on, they can be unzipped and fastened just before the dive – perfectly sealing the whole suit.

Diving Setups Part 3

Harness adjustment Text Wojciech A. Filip

You should be one with the tank on your back. It should only move when you do and exactly in the same direction.

CAUTION! Read the entire text before starting the adjustment – it contains important information that will help you through the process.

he simplest way to control your buoyancy is to control all equipment elements. If your tank is moving up and

down or sideways, it interferes buoyancy control and the diver’s position both under water and on the surface. Importantly, this also applies to a diver who needs emergency assistance. Rescue will be more efficient if the equipment stabilizes the diver in a predictable manner. Proper selection and subsequent adjustment of the way the tank is attached to the diver is crucial both for a beginner, allowing them to master buoyancy much more quickly, as well as for an experienced diver, who will receive a precise tool allowing them to achieve their diving objectives*. Your tank should be attached to the buoyancy system already when gearing up – this can typically be done almost perfectly in any system. This article describes how to adjust the buoyancy system to the diver so that it does not move on their back.

re: 2. Put on the plate with the harness – make sure the harness straps are not twisted. Harness adjustment Take as much time with the process as you need to make it right. Proper adjustment of the harness translates into: ●● your position underwater and ease of buoyancy control, ●● gas consumption and narcosis level, ●● teamwork, ●● easy use of a scooter, ●● being able to quickly adjust your harness to both a drysuit and thin neoprene in… 3 seconds, ●● your position on the surface with high waves, ●● gearing up and removing your rig under any conditions. Once you correctly adjust your harness, it will allow you to do anything while diving, without risking unpredictable behavior of the equipment.

caution! Before you extend the shoulder straps, make sure that it is the underwear, undersuit or drysuit. To make sure which piece of your gear restricts your movement, remove your drysuit and undersuit. Check if you can raise your arms freely when wearing only your underwear, then while wearing underwear and the undersuit, and finally, wearing the whole kit along with the drysuit – you should replace the element that prevents you from moving with an appropriately selected one.

Before you start adjusting the harness, soak it thoroughly in warm water and adjust all its parts while it is wet. This mainly applies to parts with slide buckles that allow harness length adjustment. It is much easier to move the harness through slide buckles when it is wet. The more rigid the harness is, the more important it becomes to soak it thoroughly for adjustment.

know that webbing usually comes in several rigidity levels. The more rigid the webbing, the more convenient it is to use. Our impression is usually the opposite, but it is the soft webbing that digs into your shoulders most frequently. Rigid webbing, on the other hand, supports uniform distribution of equipment weight while carrying it around. Additionally, it is much easier to wear and remove a harness made of rigid webbing compared to a harness made of soft webbing, which tends to roll up and curl.

Interested in the topic of adjusting your own equipment? Not sure if a harness is a good solution for you? You’ve got the equipment, but don’t know how to go about adjusting it? Book a free session and visit the Tecline Academy, where you’ll find all the skills and knowledge you need.

*in specific, narrow dive sites, a loosely fitted setup may prove to be more advantageous. It allows not only to move the tank around the diver, but also to disconnect it temporarily and swim with it in front of/behind the diver. This is the sidemount setup, where the tanks are placed alongside the diver.
