They are popular because they simplify scuba diving equipment configuration, but many divers don&#8217;t consider the potential drawbacks.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>AIR-2 systems combine AAS and LPI functions into a single unit, simplifying scuba diving equipment configuration.<\/li>\n\n\n\n<li>Many divers overlook the potential drawbacks of using AIR-2 systems.<\/li>\n\n\n\n<li>Switching to AIR-2 means learning and practicing a different air-sharing protocol, which involves primary donation to the buddy out of your own mouth and switching to the AIR-2.<\/li>\n<\/ul>\n\n\n\n<p>If you&#8217;re going to change your AAS system to something different; DO remember that you&#8217;ll need to learn and practice an entirely different air-sharing protocol. In the case of AIR-2, that&#8217;ll mean primary donation to the buddy (out of your own mouth) and YOU switch to the AIR-2.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"1000\" height=\"1300\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2020\/11\/air-2-bc-octopus-5th-generation.jpg\" alt=\"AIR-2 Octopus AIR2 inflator regulator LPI\" class=\"wp-image-15667\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2020\/11\/air-2-bc-octopus-5th-generation.jpg 1000w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2020\/11\/air-2-bc-octopus-5th-generation-231x300.jpg 231w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2020\/11\/air-2-bc-octopus-5th-generation-788x1024.jpg 788w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2020\/11\/air-2-bc-octopus-5th-generation-768x998.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<div class=\"scuba-b4-h2-2\" style=\"margin-top: 10px;margin-bottom: 10px;\" id=\"scuba-2123301715\"><div class=\"scuba-adlabel\">Sponsored Link<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9354033900485448\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-9354033900485448\" \ndata-ad-slot=\"2393012471\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"false\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"An-AIR-2-adds-skill-and-protocol-complications\"><\/span>An AIR-2 adds skill and protocol complications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>That&#8217;s more complicated, so you&#8217;ll need to rehearse it quite a few times to make the <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/mastering-competency-scuba-diving-competent-diver\/\">skill<\/a> reliable.
