The military market is similarly constrained by small quantities, and there is a lot of overlap with commercial equipment where the applications are similar, but the technical requirements for stealth operations drive development of different equipment. </p><p>Recreational scuba and snorkelling are the largest markets, in which there is the most competition between manufacturers for market share, and in which the buyers are least knowledgeable about the technology and most susceptible to persuasion by advertising. </p><p>Technical diving is a niche market, where the buyers are willing to take higher risks than commercial operators, and there is enough money available to support a small number of manufacturers developing new technology. Scientific diving is also a small market, and tends to overlap the other sectors, using what is available, and occasionally driving development of new technology for special applications. </p> <div class="mw-heading mw-heading3"><h3 id="History">History</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Diving_equipment&action=edit&section=18" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Timeline_of_diving_technology" title="Timeline of diving technology">Timeline of diving technology</a></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/wiki/History_of_underwater_diving" title="History of underwater diving">History of underwater diving</a></div> <p>With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment which the technology allows divers to partially overcome. </p> <div class="mw-heading mw-heading3"><h3 id="DEMA">DEMA</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Diving_equipment&action=edit&section=19" title="Edit section: DEMA"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1257001546"><table class="infobox vcard"><caption class="infobox-title fn org">Diving Equipment and Marketing Association</caption><tbody><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Abbreviation</th><td class="infobox-data nickname">DEMA</td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Formation</th><td class="infobox-data note">1987</td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Type</th><td class="infobox-data"><a href="/wiki/Trade_association" title="Trade association">Trade Association</a></td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Legal status</th><td class="infobox-data"><a href="/wiki/Mutual-benefit_nonprofit_corporation" title="Mutual-benefit nonprofit corporation">Mutual-benefit nonprofit corporation</a><br />Incorporated in <a href="/wiki/California" title="California">California</a>,</td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Purpose</th><td class="infobox-data">Advocacy for the <a href="/wiki/Recreational_diving" title="Recreational diving">recreational diving</a> industry</td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Headquarters</th><td class="infobox-data"><a href="/wiki/California" title="California">California</a>, United States of America</td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;"><div style="display: inline-block; line-height: 1.2em; padding: .1em 0;">Membership </div></th><td class="infobox-data">1,300</td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;">Website</th><td class="infobox-data"><span class="url"><a rel="nofollow" class="external text" href="http://www.dema.org">www<wbr />.dema<wbr />.org</a></span></td></tr><tr><th scope="row" class="infobox-label" style="padding-right:0.6em;"><div style="display: inline-block; line-height: 1.2em; padding: .1em 0;">Formerly called</div></th><td class="infobox-data nickname">Diving Equipment Manufacturers Association<sup id="cite_ref-Brylske_37-0" class="reference"><a href="#cite_note-Brylske-37"><span class="cite-bracket">[</span>37<span class="cite-bracket">]</span></a></sup></td></tr></tbody></table> <p>The Diving Equipment and Marketing Association (DEMA, formerly the Diving Equipment Manufacturers Association),<sup id="cite_ref-Brylske_37-1" class="reference"><a href="#cite_note-Brylske-37"><span class="cite-bracket">[</span>37<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-DEMA_about_38-0" class="reference"><a href="#cite_note-DEMA_about-38"><span class="cite-bracket">[</span>38<span class="cite-bracket">]</span></a></sup> is an international organization for the promotion and growth of the <a href="/wiki/Recreational_diving" title="Recreational diving">recreational scuba diving</a> and <a href="/wiki/Snorkeling" title="Snorkeling">snorkeling industry</a>.
