The greatest danger to snorkelers are inshore and leisure craft such as jet skis, speed boats and the like. A snorkeler is often submerged in the water with only the tube visible above the surface. Since these craft can ply the same areas snorkelers visit, the chance for accidental collisions exists. Sailboats and sailboards are a particular hazard as their quiet propulsion systems may not alert the snorkeler of their presence. A snorkeler may surface underneath a vessel and/or be struck by it. Few locations demarcate small craft areas from snorkeling areas, unlike that done for regular beach-bathers, with areas marked by buoys. Snorkelers may therefore choose to wear bright or highly reflective colors/outfits and/or to employ dive flags to enable easy spotting by boaters and others.
To measure your foot length, sit down on a chair and place your foot flat on a piece of paper. Trace the foot by holding a pencil vertically and outlining the foot. The longest toe and back of heel are the most important measurements. Using a ruler, measure the distance from the bottom of the heel to the tip of the longest toe. Record the result in both inches and centimeters and use these measurements to find your size in the chart. If one foot is larger than the other, the measurements for the larger foot should be used.
1939: First side-mounted swimmers’ breathing tube patent filed. In December 1939, expatriate Russian spearfisherman Alexandre Kramarenko files a patent in France for a breathing tube worn at the side of the head with a ball valve at the top to exclude water and a flutter valve at the bottom. Kramarenko and his business partner Charles H. Wilen refile the invention in March 1940 in the USA, where their "underwater apparatus for swimmers" is granted US patent 2,317,236 on 20 April 1943; after entering production in France, the device is called "Le Respirator". The co-founder of Scubapro Dick Bonin is credited with the introduction of the flexible-hose snorkel in the mid-1950s and the exhaust valve to ease snorkel clearing in 1980. In 1964, US Divers markets an L-shaped snorkel designed to outperform J-shaped models by increasing breathing ease, cutting water drag and eliminating the "water trap". In the late 1960s, Dacor launches a "wraparound big-barrel" contoured snorkel, which closely follows the outline of the wearer's head and comes with a wider bore to improve airflow. The findings of the 1977 report "Allergic reactions to mask skirts, regulator mouthpieces and snorkel mouthpieces" encourage diving equipment manufacturers to fit snorkels with hypoallergenic gum rubber and medical-grade silicone mouthpieces (see Figure 5). In the world of underwater swimming and diving, the side-mounted snorkel has long become the norm, although new-generation full-face swim masks with integrated snorkels are beginning to grow in popularity for use in floating and swimming on the surface.
Ordered this for my adventurous kids to use at the lake we swim in and they had a blast! They fought over who got to use it next, and never complained about fit, fogging or anything. And this, from kids who take regular goggles off every 5 seconds to wipe and adjust, is a godsend. One of them even wore it in the bathtub tonight! Product came very quickly, in nice sleek packaging with a convenient carrying case for the mask. Very happy!
