Hogarthian Basic Diver - Fundamentals

Hogarthian diving (Doing It Right) is a holistic diving system that is designed to maximize diving fun while minimizing effort and risk. The Hogarthian (DIR) system is practiced by divers around the world in environments ranging from shallow coral reefs to deep ocean wrecks. Hogarthian (DIR) system is creating a revolution in diving, minimizing a diver's effort while promoting systems to maximize safety and efficiency.
Without bulky configurations that leave equipment dangling from a diver’s body, individuals are free to move easily through the water. When merged with other Hogarthian (DIR) skills such as team diving and precision diver control, individuals are able to appreciate a whole new way of diving, having more fun while diving safer and more responsibly. Simply put, these techniques enable divers to maximize their ability and eliminate the impediments common in conventional diving.
Hogarthian (DIR) techniques have gained extensive international popularity with divers that range in experience from newly certified to long time diving professionals. The rapid utilization of Hogarthian (DIR) in the technical diving world has led some individuals to believe that Hogarthian (DIR) is primarily designed for these environments. While it is true that technical divers were the most rapid adaptors of Hogarthian (DIR) principles it is not accurate to imagine that Hogarthian (DIR) solves primarily technical diving problems. Actually Hogarthian (DIR) diving  addresses diving's most fundamental problems with solutions that apply equally to shallow open water divers, leading edge technical divers, and even military special forces applications.
In truth, Hogarthian (DIR) techniques and procedures are effective precisely because they are the essence of simplicity. As such this system could be said to be equally or more valuable for recreational divers who are less experienced individuals and not as likely to be able to overcome the stress associated with improper techniques. These principles focus on creating a foundation of skills and procedures that serve as a platform around which divers can build from basic open water excursions to the most advanced forms of technical diving.

Course Content
The Hogarthian basic course instructs divers in the fundamental aspects of Hogarthian (DIR) diving, increasing divers fun and efficiency while reducing stress and diver risk. Instruction focuses on providing divers with a robust understanding of Hogarthian (DIR) techniques as they apply primarily to recreational diving. Skills will focus on a range of skills including: improving diver proficiency, team building skills, precision buoyancy control, perfecting diver trim, reducing drag, equipment configurations, refining propulsion techniques, improving underwater communication, effective risk evaluation and efficient dive planning.
