Scuba Diving: Doing It Right (DIR)
An Overview of the DIR and Hogarthian Methodologies
In the diving world, these new approaches are surrounded by hype. But what do they really mean?
A fairly new comer to the dive world (mid-1990’s) is the DIR or Doing it Right methodology. DIR grew out of dissatisfaction with the state of the dive industry as far as training, specifically in the realm of cave and overhead environment diving. Depending on the instructor who provided the initial training a diver could be excellent or dangerous to themselves and other divers. The DIR methodology consists of a philosophy of proper equipment configuration, proper training, a team mentality and a generally healthy lifestyle. DIR is promoted by the Global Underwater Explorers (GUE) organization their website is if you want to get more detailed information than I am able to provide in this short article.
DIR uses the Hogarthian equipment configuration utilizing a back plate and wing, a one-piece continuous web harness with specific D-ring placement and a crotch strap. The entire concept is gear minimalization and elimination of points of failure. The configuration includes a long (5 to 7 foot) primary hose, a shorter (22 inch) backup hose with a bungeed backup regulator worn around the neck, properly sized inflator hoses for dry suit and wing and a simple pressure gauge. The configuration allows for either a single, or double, tank configuration and the use of either an K, H or valve manifold with isolator in the case of doubles. A K-valve is the standard single tank valve, an H-valve allows two primary regulators off of a single tank and a manifold with isolator consists of two-K valves connected by a pipe containing an isolator valve. The Hogarthian system also allows for the use of a proper exposure suit, solid (non-split fins) and minimal volume masks. Non-split fins are suggested because they allow easier use of kick methods such as the back kick.
Gear standardization also extends to the use of canister lights (a light where the battery is a rechargeable pack contained in a waterproof canister with a waterproof cable leading to a light head which provides a minimal wattage) cutting devices, backup lights and the placement of gear on the harness D rings and drysuit pockets. This standardization is designed to allow team members to rapidly assist other team members without having to search for their or others, gear.
In addition to gear and configuration, training is a key component of the DIR methodology with multiple levels and specific tasks and grading criteria that ensures the diver has the proper skills to dive safely in a team. A review of the DIR Standards 2006 Version 4, shows very specific requirements for all levels of DIR qualifications. The standards also allow for removal of certification as well as disqualification of instructors, something the other qualification agencies such as PADI could do well to emulate.

In short, the DIR methodology provides disciplined, qualified divers who follow standards and know how to work as a team. These are all qualifications that all divers, no matter their training affiliation should emulate.
