Sidemount began originally in the UK as a specialist technique used in sump exploration. <\/p>\n\n\n\n<p>By the 1970s it had emigrated across the Atlantic and began to be used within the Mexican and Florida cave-diving communities. In 2012 sidemount went mainstream when it was adopted by many of the large recreational dive training agencies as a specialty course. <\/p>\n\n\n\n<p>Over the last decade, it has surged in popularity across the globe and has become an active community on social media.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_80 ez-toc-wrap-center counter-hierarchy ez-toc-counter ez-toc-transparent ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title ez-toc-toggle\" style=\"cursor:pointer\">Article Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/history-of-sidemount-diving\/#The-1960s-%E2%80%93-UK-sump-diving\" >The 1960\u2019s \u2013 UK sump diving<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/history-of-sidemount-diving\/#The-%E2%80%98English-system\" >The \u2018English system\u2019<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/history-of-sidemount-diving\/#The-1970s-%E2%80%93-Florida-Mexico\" >The 1970\u2019s \u2013 Florida &amp;

During \u2018dry\u2019 explorations of Wookey Hole, the River Axe, and other underground systems, divers occasionally encountered submerged passages that blocked further exploration. These cavers began incorporating SCUBA equipment specifically to progress beyond underwater areas.<\/p>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>&nbsp;A section of dry cave passage that is filled with water is called a sump. Therefore sump diving is&nbsp;<strong>a mixture of dry caving and cave diving<\/strong>. These are often times some of the more physically demanding projects as team members are required to haul heavy gear through multiple dry passages. Also, these sumps are typically very low in visibility due to silt disturbance.<\/p><cite>OCDA, <a href=\"https:\/\/www.ocda.org\/exploration\/sump-diving\/\" target=\"_blank\" rel=\"noreferrer noopener\">Sump Diving<\/a><\/cite><\/blockquote><\/figure>\n\n\n\n<p>However, because they operated in very confined spaces, and most exploration remained primarily \u2018dry\u2019, they began experimenting and improvising with extremely minimalist configurations, minimizing bulk, allowing cylinders to be easily removed\/replaced, and retaining the capacity to squeeze through the tightest restrictions.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><img decoding=\"async\" width=\"1152\" height=\"2048\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/sidemount-diving-history-edited-scaled.jpg.webp\" alt=\"sidemount diving history\" class=\"wp-image-18512\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/sidemount-diving-history-edited-scaled.jpg 1152w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/sidemount-diving-history-edited-169x300.jpg 169w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/sidemount-diving-history-edited-576x1024.jpg 576w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/sidemount-diving-history-edited-768x1365.jpg 768w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/sidemount-diving-history-edited-864x1536.jpg 864w\" sizes=\"(max-width: 1152px) 100vw, 1152px\" \/><figcaption class=\"wp-element-caption\">A very early sidemount rig for sump \u2018diving\u2019 in the UK<\/figcaption><\/figure>\n\n\n\n<p>The nature of these \u2018dives\u2019 in cramped sumps did not prioritize the need for buoyancy control or underwater propulsion \u2013 so the bare minimum needed was a mask, a cylinder, a regulator, a method of attachment to the body, and, only on rare occasions, a set of fins.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The-%E2%80%98English-system\"><\/span>The \u2018English system\u2019<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p>Many of these early sump explorers adopted an approach based upon a sturdy belt, with an attached cam-band, that allowed a cylinder to be dropped in and carried alongside the outer thigh.<\/p>\n\n\n\n<p>This allowed them to crawl, or wriggle, through the dry cave sections, whilst presenting a secure method of attachment for passing through submerged areas.<\/p>\n\n\n\n<p>Swimming efficiency, reduced water resistance, trim, and buoyancy control were not generally required due to the nature of those caves.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"240\" height=\"320\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2012\/05\/sidemount-diving-history-1.jpg\" alt=\"sidemount diving history 1\" class=\"wp-image-5352\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2012\/05\/sidemount-diving-history-1.jpg 240w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2012\/05\/sidemount-diving-history-1-225x300.jpg 225w\" sizes=\"(max-width: 240px) 100vw, 240px\" \/><figcaption class=\"wp-element-caption\">English cave explorer with \u2018sump bottle\u2019 side-mounted<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p>At the time, this approach to \u2018wet\u2019 cave exploration was generally called the \u2018English System\u2019.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The-1970s-%E2%80%93-Florida-Mexico\"><\/span>The 1970\u2019s \u2013 Florida &amp;
