{"product_id":"2940014285346","title":"Your Guide To Scuba Diving","description":"Many people think that space is our final frontier – and that is not entirely true.\u003cbr\u003eWhile it is more difficult to get to outer space, we probably know more about the\u003cbr\u003evarious planets and environments in space than we do about what lies beneath\u003cbr\u003ethe surface of our oceans.\u003cbr\u003eJust as in outer space, there is a whole environment, or ecosystem, under the\u003cbr\u003ewaters that cover 75% of our planet, with 70% of our planet being ocean waters.\u003cbr\u003eBeneath those waters there really is an entirely new world -a world full of beauty\u003cbr\u003eand mystery that few humans have the opportunity to experience.\u003cbr\u003eBut the lucky few who do have the opportunity to experience this vast under\u003cbr\u003ewater world are able to do so because they are scuba divers. Obviously, human\u003cbr\u003ebeings cannot breathe underwater, so instead, they rely on a portable respiratory\u003cbr\u003esystem that is self contained.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eYou have probably seen shows that depict scuba divers. You may have seen pictures that are taken under the water of scuba divers as well. It all looks very easy and in a sense, it is. But there is a great deal that you must know before you can participate in your first dive. Do not assume that the guy at the sports store or the dive shop can tell you everything you need to know when you purchase your diving equipment. You need to take scuba diving lessons and become a certified diver. This is necessary for your own safety, as well as for the safety of those who are diving with you. A lot can go wrong on a dive.\u003cbr\u003e\u003cbr\u003eTable of Contents\u003cbr\u003ePage 3…..The Ocean – Our Most Unexplored Frontier\u003cbr\u003ePage 4…..The History of Scuba Diving\u003cbr\u003ePage 6…..Diver Education\u003cbr\u003ePage 8…..Different Types of Diving\u003cbr\u003ePage 10…..Different Scuba Diving Skill Levels\u003cbr\u003ePage 12…..Are You Healthy Enough to Dive?\u003cbr\u003ePage 15…..Basic Diving Equipment\u003cbr\u003ePage 20…..The Divers Respiratory System\u003cbr\u003ePage 22…..Finding Your Way Under Water\u003cbr\u003ePage 24…..Scuba Diving Safety Guidelines\u003cbr\u003ePage 26…..About Under Water Pressure and Decompression\u003cbr\u003ePage 27…..Gravity Underwater\u003cbr\u003ePage 28…..Underwater Dangers\u003cbr\u003ePage 33…..Scuba Diving Organizations and Communities\u003cbr\u003ePage 32…..Where To Dive\u003cbr\u003ePage 33…..Dive Vacations\u003cbr\u003ePage 35…..Diver’s Glossary","brand":"Dawn Publishing","offers":[{"title":"Default Title","offer_id":47165237690608,"sku":"2940014285346","price":1.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014285346_p0.jpg?v=1763604850","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014285346","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
