1938: First swimmers’ mask with integrated breathing tubes. In 1938, French naval officer Yves Le Prieur introduces his "Nautilus" full-face diving mask with hoses emerging from the sides and leading upwards to an air inlet device whose ball valve opens when it is above water and closes when it is submerged. In November 1940, American spearfisherman Charles H. Wilen files his "swimmer’s mask" invention, which is granted US patent 2,317,237 of 20 April 1943. The device resembles a full-face diving mask incorporating two breathing tubes topped with valves projecting above the surface for inhalation and exhalation purposes. On 11 July 1944, he obtains US design patent 138,286 for a simpler version of this mask with a flutter valve at the bottom and a single breathing tube with a ball valve at the top. Throughout their heydey of the 1950s and early 1960s, masks with integrated tubes appear in the catalogues of American, Australian, British, French, German, Greek, Italian and Spanish swimming and diving equipment manufacturers. Meanwhile, in 1957, the US monthly product-testing magazine Consumer Reports concludes that "snorkel-masks have some value for swimmers lying on the surface while watching the depths in water free of vegetation and other similar hazards, but they are not recommended for a dive 'into the blue'". According to an underwater swimming equipment review in the British national weekly newspaper The Sunday Times in December 1973, "the mask with inbuilt snorkel is doubly dangerous (...) A ban on the manufacture and import of these masks is long overdue in Britain". In a decree of 2 August 1989, the French government suspends the manufacture, importation and marketing of ball-valve snorkel-masks. By the noughties, just two swim masks with attached breathing tubes remain in production worldwide: the Majorca sub 107S single-snorkel model and the Balco 558 twin-snorkel full-face model, both manufactured in Greece. In May 2014, the French Decathlon company files its new-generation full-face snorkel-mask design, which is granted US design patent 775,722 on 3 January 2017, entering production as the "Easybreath" mask (see Figure 3) designated for surface snorkelling only.

Technically, nature can’t deliver a sure-thing when it comes to animal encounters, but Isla Mujeres, found 9 miles offshore of Cancun, Mexico, is as good as it gets. June through August, the turquoise waters are thick with the spawn of bonito tuna — becoming a buffet for whale sharks, the world’s largest fish at up to 41½ feet long. Local tour operators can drop you in the path of these fish, allowing encounters that can sometimes last up to 20 minutes. This area is also home to two underwater statue parks filled with more than 500 life-size sculptures in 12 to 20 feet of water.

For scuba diving, the primary piece of equipment you’ll need is a pressurized gas tank with a tube. This tank will be your air supply while you’re underwater. A wetsuit is also necessary to keep your body temperature regulated, even in tropical waters. Foot fins will help you through the water, propelling your movement. And lastly, if you are not an experienced diver, you’ll want a guide to accompany you. At Mai Dive, we make sure your scuba diving in Fiji experience is as safe and enjoyable as it is unforgettable. We create daily dive plans tailored to the requirements of our diving and snorkeling guests that factor in your experience level, the tides, the water conditions and the weather.
It is a single location dive. A dive the late afternoon during the light and then we come up as planned just before the sunset. We watch the sunset, a Keys favorite, and then prepare for the second dive. Once dark, we dive the second dive to witness an amazing transformation of the reef. New species coming out of the coral, new activity all around, and even surface bioluminescence that you will be delighted to see. It’s a new world down there and you will be one of the few lucky ones to see it all happen in front of you.
It is no less beautiful once you land, with posh resorts in which tiny thatched-roof bungalows are perched over the water, each with a private pool. Bora Bora is also a divers’ paradise, with healthy unspoiled reefs rich with sea creatures of all kinds. The dormant volcano rises to two peaks, Mount Pahia and Mount Otemanu, the highest point being 727-feet high and offering spectacular views and great hikes.

While the two-piece swimsuit as a design existed in classical antiquity, the modern design first attracted public notice in Paris on July 5, 1946. French automotive engineer Louis Réard introduced a design he named the "bikini", adopting the name from the Bikini Atoll in the Pacific Ocean, which was the colonial name the Germans gave to the atoll, transliterated from the Marshallese name for the island, Pikinni.
There are two parking lots and they tend to fill up fast on weekends, so you might have to settle for on-street parking near here. The Ocean Beach Bike Path runs inland along the river from here for bikers and runners. The extreme north end of this beach is called Dog Beach and it’s overrun with happy pooches. To get here, take the Ocean Beach Freeway (I-8) west to the end then follow Sunset Cliffs Boulevard to West Point Loma Blvd which ends at the beach.
Modern designs use silicone rubber in the mouthpiece and one-way clearing and float valves due to its resistance to degradation and its long service life. Natural rubber was formerly used, but slowly oxidizes and breaks down due to ultraviolet light exposure from the sun. It eventually loses its flexibility, becomes brittle and cracks, which can cause clearing valves to stick in the open or closed position, and float valves to leak due to a failure of the valve seat to seal. In even older designs, some snorkels were made with small "ping pong" balls in a cage mounted to the open end of the tube to prevent water ingress. These are no longer sold or recommended because they are unreliable and considered hazardous. Similarly, diving masks with a built-in snorkel are considered unsafe by scuba diving organizations such as PADI, BSAC because they can engender a false sense of security and can be difficult to clear if flooded.
The Park and Ocean Railroad ran along Lincoln Way on the south edge of Golden Gate Park and then turned north into the western end of the Park along La Playa Street. This standard-gauge railway began service on 1 December 1883 using four locomotives built by Baldwin Locomotive Works in November 1880 for the Central Pacific Railroad but lettered Market Street, Park & Cliff Railroad. These four 0-4-2T (tank locomotives) (C/N 5357, 5357, 5375 & 5377) were joined by four 2-4-2T Baldwins (C/N 7201, 7203, 7238 & 7243) built in March 1884. When the line was electrified in 1900, locomotive #1 went to the Mendocino Lumber Company, three of the 2-4-2Ts went to Canadian Collieries, and the remaining four became Southern Pacific Transportation Company numbers 20, 21, 22 and 80. Number 20 was preserved at Travel Town Museum in 1954.
