The origins of the approach to equipment taken by DIR practitioners can be found in the 'Hogarthian' equipment configuration attributed to <a href="/wiki/Bill_Main" class="mw-redirect" title="Bill Main">William Hogarth Main</a>.<sup id="cite_ref-hog1997_4-0" class="reference"><a href="#cite_note-hog1997-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> These individuals, along with many others, were attempting to develop equipment and procedures to allow the safer exploration of the deep submerged caves in the area. Successfully carrying out the advanced diving required for deep cave penetration, as in the Woodville Karst Plain Project, places a great need to focus on the fundamentals of exactly how such diving should be carried out, and how equipment should be selected and configured for this type of diving, to maximise mission effectiveness and minimise risk. The DIR approach was originally confined to cave diving, but soon spread to other forms of <a href="/wiki/Technical_diving" title="Technical diving">technical diving</a>.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

This is not to say that DIR equipment and configuration is immutable and can not be improved, but that all the consequences to the system must be considered when a variation is contemplated, so that knock-on effects can be avoided. </p><p>The basic principle of DIR diving also includes familiarity of all divers in the team with all equipment used by the team, and all the procedures intended to be used by the team, and that interchangeability of DIR divers between teams is highly desirable. The natural consequence is that changes are not easily accepted unless very well motivated. This may be interpreted as inflexibility by persons who do not analyse the philosophy of the system.<sup id="cite_ref-fund2006-66-67_1-1" class="reference"><a href="#cite_note-fund2006-66-67-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>When there is a choice between two items of equipment with the same purpose, and one is clearly better than the other for a reason that affects risk and safety, the DIR philosophy insists that only use of the safer item is doing it right. </p><p>The configurations and procedures recommended by the DIR proponents did not spring into existence fully formed and perfect, they were developed, largely by trial and error, and significantly by <a href="/wiki/William_Hogarth_Main" title="William Hogarth Main">William Hogarth Main</a>, who continues experimenting with configurations and equipment in the interests of improving the system. </p><p>The DIR equipment system can be described as minimalist. Items of equipment that do not serve a useful purpose on a dive are considered a liability. Redundancy is provided where necessary within the personal equipment of the diver, and where possible by availability of team equipment. Multiple redundancy across personal and team equipment is only resorted to when necessary. </p><p>Streamlining and maintaining a low profile and cross sectional area are important considerations but effectiveness and robust applicability to a wide range of environments are possibly more important, as they allow a basic core configuration that is effective in virtually any recreational diving situation, and allow standardisation of procedures, which in turn lets the diving team be assembled from similarly trained and equipped divers, who integrate more easily into an effective team. In this context, streamlining includes the aspect of reducing hydrodynamic drag when swimming, but more importantly, the reduction of entanglement and entrapment hazards due to equipment components to a minimum. </p><p>This philosophy does not preclude the use of equipment that is necessary for a special task, but would be applied to the choice of the equipment and how it is transported and deployed. </p><p>The standard DIR configuration is also known as the Hogarthian rig in recognition of the development work done on it by William Hogarth Main (Bill Main). </p> <div class="mw-heading mw-heading3"><h3 id="Backplate">Backplate</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Doing_It_Right_(scuba_diving)&action=edit&section=17" title="Edit section: Backplate"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The backplate and harness forms the foundation of the DIR diving equipment system.

The approved valve knob is hard rubber or non-brittle plastic, which flexes to absorb much of the impact energy, with a metal insert, so the connection to the spindle is less likely to strip. Spring loading of the valve knob can also absorb impact loads, but only from some directions. Hard plastic and metal knobs are not approved. Hard plastic knobs may be brittle and break under impact, and metal knobs are more likely to transfer the full impact to the spindle, thus a greater risk of bending or shearing the spindle and rendering the valve inoperable. If the valve is rolled off (closed by friction against the environment) at the same time, the gas supply is isolated and unavailable to the diver.<sup id="cite_ref-fund2006-103-104_59-0" class="reference"><a href="#cite_note-fund2006-103-104-59"><span class="cite-bracket">[</span>59<span class="cite-bracket">]</span></a></sup> Almost all knobs are currently (2018) made of hard rubber or non-brittle plastic. </p><p>It is possible to accidentally turn off an isolation valve during a fill or a safety drill, and a closed isolator can cause problems. The isolator is normally left completely open, so the manifolded cylinders maintain equal pressure during filling and use, and are closed during an emergency to prevent gas loss from both cylinders, during safety drills, or to identify a fault. Symptoms of a closed isolator depend on which tank the diver is breathing from. If the gauge is on the same tank that the diver is breathing from, the diver may notice an unusually quick reduction in pressure, and mistakenly believe that they are running out of gas. If the gauge and regulator in use are on separated by the isolator, the gauge will continue to read the same pressure as the other tank is depleted. When the cylinder in use is emptied, the gauge will still read full, and the diver may assume that the regulator has malfunctioned. This is only likely to happen to divers that are paying little attention to their gas supply, as an apparently abnormally fast or slow depletion of gas supply is an indication that valve status should be checked, and if necessary, corrected.<sup id="cite_ref-Equipment_60-0" class="reference"><a href="#cite_note-Equipment-60"><span class="cite-bracket">[</span>60<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading4"><h4 id="Back_cylinders">Back cylinders</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Doing_It_Right_(scuba_diving)&action=edit&section=30" title="Edit section: Back cylinders"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1251242444"><table class="box-Empty_section plainlinks metadata ambox mbox-small-left ambox-content" role="presentation"><tbody><tr><td class="mbox-image"><span typeof="mw:File"><a href="/wiki/File:Wiki_letter_w_cropped.svg" class="mw-file-description"><img alt="[icon]" src="//upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/20px-Wiki_letter_w_cropped.svg.png" decoding="async" width="20" height="14" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/30px-Wiki_letter_w_cropped.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/1c/Wiki_letter_w_cropped.svg/40px-Wiki_letter_w_cropped.svg.png 2x" data-file-width="44" data-file-height="31" /></a></span></td><td class="mbox-text"><div class="mbox-text-span"><b>This section is empty.</b> You can help by <a class="external text" href="https://en.wikipedia.org/w/index.php?title=Doing_It_Right_(scuba_diving)&action=edit&section=">adding to it</a>. <span class="date-container"><i>(<span class="date">February 2017</span>)</i></span></div></td></tr></tbody></table> <div class="mw-heading mw-heading4"><h4 id="Stage_and_decompression_cylinders">Stage and decompression cylinders</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Doing_It_Right_(scuba_diving)&action=edit&section=31" title="Edit section: Stage and decompression cylinders"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A stage cylinder contains gas intended to extend bottom time.

This is because some see the insistence on uniformity as an indictment of practices that do not abide by DIR principles. However, there is nothing essentially hostile or critical about DIR; in its most basic form, it is ultimately pragmatic, promoting the concept of uniformity within and among teams of divers. However, there is a certain degree of legitimate tension generated by imprudent advocates of DIR, who, having personally benefited from the system, become evangelical in promoting what they understand of its tenets.

Most other technical diver training agencies recommend using two — a primary and a backup. <i>Doing it Right: The Fundamentals of Better Diving</i> page 119 lists 13 reasons why DIR consider dive computers to be bad. However, some of these appear strange - including the suggestion that they are expensive (modern dive computers are cheap, especially when compared with the cost of other equipment and diving gases recommended by the DIR approach), and too conservative (the approach to decompression promoted by DIR - <a href="/wiki/Ratio_decompression" title="Ratio decompression">ratio decompression</a> - leads to decompression profiles of varying conservatism, but are often very conservative),<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

DIR is solidly committed to buddy or "team" diving. When a diving team is sufficiently competent and disciplined, team equipment redundancy can compensate for lack of personal equipment redundancy, while reducing physical loading of each diver, by ensuring that the team can compensate for any reasonably foreseeable failure within an acceptable time frame for the specific incident. Each diver must be able to manage an emergency alone long enough for the other members to take the necessary action to assist, and each team member must be available and ready to give the needed assistance. </p> <div class="mw-heading mw-heading3"><h3 id="Standardised_equipment_configuration">Standardised equipment configuration</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Doing_It_Right_(scuba_diving)&action=edit&section=55" title="Edit section: Standardised equipment configuration"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>DIR requires that all divers in the team should have standardised equipment configurations to facilitate assistance. Whereas other conventional training agencies promote customising equipment for particular scenarios and individuals (sometimes called "personal preference"), DIR strongly advocates everyone always being outfitted similarly (with the exception of task-specific equipment). <i>Doing it Right: The Fundamentals of Better Diving</i> page 67 says: "It is the perfect system in zero visibility as well as in crystal clear water. The DIR system requires no modification to function effectively and efficiently in different environments ... In freezing water these divers use dry gloves and thicker undergarments and possibly electric heat. Cold water divers use slightly larger bolt-snaps. Otherwise, exactly the same system is used whether the dive is below ice or in the balmy tropics."
