Whilst the primary skills and drills taught in these courses are identical wherever they are taught, the focus and philosophy of training can vary significantly by region or by the individual instructor.<\/p>\n\n\n\n<p>In this article, I will attempt to explain the general components and structure of a technical wreck course, along with my personal interpretation, as a technical wreck instructor with 2 decades of teaching experience, of how I focus and run my courses here in <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/history_of_subic_bay\/\">Subic Bay<\/a>.<\/p>\n\n\n\n<p>The photos used to illustrate this article are all still shots taken from GoPro footage of a technical wreck course that I ran on the wrecks of Subic Bay in January 2016. My French student, Robin, was already a well-known cave explorer and instructor. We conducted a technical-level <a href=\"https:\/\/scubatechphilippines.com\/sidemount-courses\/raid-sidemount-course\/\">sidemount course<\/a> and fundamental skills clinic before doing the technical wreck course.<\/p>\n\n\n\n<p>The total training was 10 days. I video my courses to enable constructive post-dive debriefs and student self-analysis. This is a very effective learning tool that promotes rapid development.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"1491\" height=\"1080\"

There are 2 dives conducted per day, often lasting in excess of 90 minutes each. There is also theory study in the classroom and lots of skill rehearsals on dry land; especially with regard to guideline drills and line-laying.<\/p>\n\n\n\n<div class=\"scuba-b4-h2-2\" style=\"margin-top: 10px;margin-bottom: 10px;\" id=\"scuba-3862433801\"><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=\"The-need-for-physical-fitness\"><\/span>The need for physical fitness<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Students should be in good physical shape for this training. It demands some diver endurance and durability. <\/p>\n\n\n\n<p>Some divers prefer not to prepare for courses with physical conditioning exercise. Instead, they will get through each training day at a point of exhaustion. In turn, this can lead to degraded learning potential.

For that reason, being able to complete shut-down drills, or even mask clearances, in every possible orientation is important.<\/p>\n\n\n\n<p>Many divers, even technical divers, don&#8217;t practice their skills out of horizontal trim. Consequently, this is often a steep learning experience for them.

Restrictions are traditionally defined as spaces where two divers cannot pass through whilst sharing air side-by-side. However, for technical wreck divers, restrictions demand a much more detailed classification.<\/p>\n\n\n\n<p>There are spaces where two divers can pass whilst sharing air in long-hose, but tighter spaces might involve some time and wriggling to get through. <\/p>\n\n\n\n<p>The tightest spaces may involve:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Removing items of equipment<\/li>\n\n\n\n<li>Teamwork to pass equipment or cylinders through<\/li>\n\n\n\n<li>Safety decisions on whether the diver should pass head-first or feet-first<\/li>\n\n\n\n<li>Consideration of air-sharing support throughout the process of getting past a restriction.<\/li>\n<\/ul>\n\n\n\n<p>You can read more about <strong><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/defining-wreck-diving-restrictions\/\">defining wreck restrictions<\/a><\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"1644\" height=\"1080\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-14.jpg\" alt=\"scubatechphilippines-sidemount-technical-wreck-subic-bay\" class=\"wp-image-4987\" title=\"scubatechphilippines-sidemount-technical-wreck-subic-bay\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-14.jpg 1644w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-14-300x197.jpg 300w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-14-1024x672.jpg 1024w\" sizes=\"(max-width: 1644px) 100vw, 1644px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Learn-ingrain-and-apply-technical-wreck-skills\"><\/span>Learn, ingrain, and apply technical wreck skills<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>My training philosophy is that <em>learning<\/em>, <em>ingraining<\/em> and <em>applying<\/em> skills are fundamental to creating competent technical and overhead environment divers.<\/p>\n\n\n\n<p>When I conduct technical wreck courses here in <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/subic-bay-dive-site\/\">Subic Bay, Philippines<\/a>, I am lucky to have the <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/uss-new-york-subic-wreck-dive\/\">USS New York ACR-2 armored cruiser<\/a> as a training site.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"1500\" height=\"1080\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-13.jpg\" alt=\"scubatechphilippines-sidemount-technical-wreck-subic-bay\" class=\"wp-image-4986\" title=\"scubatechphilippines-sidemount-technical-wreck-subic-bay\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-13.jpg 1500w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-13-300x216.jpg 300w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2016\/02\/scubatechphilippines-sidemount-technical-wreck-13-1024x737.jpg 1024w\" sizes=\"(max-width: 1500px) 100vw, 1500px\" \/><\/figure>\n\n\n\n<p>This is an impressive wreck that permits extensive multiple-deck penetrations in heavy silt and confined spaces.
