A DIR configuration refers to a standardized way of organizing diving equipment based on the principles of Doing It Right (DIR). The goal of this configuration is to create a system that is simple, streamlined, reliable, and predictable, allowing divers to focus on the dive rather than managing complicated equipment setups.
Originally developed within the cave diving community and later popularized by organizations such as InnerSpace Explorers (ISE) and Global Underwater Explorers (GUE), the DIR configuration has had a major influence on modern technical diving equipment setups.
The Philosophy Behind the Configuration
A DIR configuration is not just about where equipment is placed—it is part of a larger system that combines equipment, procedures, and team diving principles. The idea is that every diver in the team uses a similar setup, so anyone can quickly understand and assist with another diver’s equipment if necessary.
A key principle of DIR is streamlining and purpose:
divers carry only the equipment they actually need, and every item has a clearly defined location. This reduces drag, minimizes clutter, and ensures that essential tools can always be found quickly—even in stressful situations.
The Backplate and Wing System
One of the core elements of a DIR configuration is the backplate and wing buoyancy system. Instead of a traditional jacket-style BC, the diver uses a metal (typically Aluminium or Stainless Steel) backplate combined with a wing-style buoyancy bladder.
This system provides several advantages:
- Improved trim and horizontal body position
- Better streamlining in the water
- A modular setup that works for both single tanks and doubles
The harness is usually a continuous one-piece webbing harness, which is simple, durable, and minimizes unnecessary potential failure points.
The Long Hose Regulator Setup
Another defining feature is the long hose primary regulator configuration.
In this setup:
- The primary regulator is on a long hose (typically around 2.1 meters / 7 feet).
- The backup regulator is worn on a short hose attached to a necklace under the diver’s chin.
In an out-of-gas situation, the diver donates the regulator they are currently breathing from and immediately switches to their backup regulator. This method simplifies gas sharing and allows divers to swim comfortably in single-file formations if necessary.
Streamlined and Essential Equipment
DIR emphasizes carrying only essential equipment and placing it in consistent, easy-to-reach locations. Every item should be secured close to the body to reduce drag and avoid entanglement.
Typical equipment carried in a DIR configuration includes:
- A primary dive light with a Goodman handle
- Backup lights clipped to the harness
- An SPG (pressure gauge) clipped to the left hip D-ring
- At least one cutting device accessible with either hand
- A backup mask stored in a pocket
- A closed DSMB (Delayed Surface Marker Buoy) with a spool or reel
- Wetnotes or a small notebook for communication and dive planning
Each item has a standardized position, making it easy for both the diver and their teammates to locate it quickly.
Consistency Across the Team
One of the major benefits of a DIR configuration is consistency across divers. When everyone uses a similar setup, teammates can easily identify where regulators, valves, lights, and emergency equipment are located.
This consistency is especially valuable in complex dives such as deep technical dives, wreck penetrations, or cave environments, where quick problem-solving and teamwork are essential.
A System That Supports Skills
A DIR configuration is designed to support strong diving fundamentals such as buoyancy control, trim, propulsion techniques, and situational awareness. By keeping equipment simple and streamlined, divers can focus on developing these core skills rather than managing unnecessary gear.
Final Thoughts
The DIR configuration has become one of the most influential equipment setups in modern technical diving. By emphasizing simplicity, standardization, and streamlining, it provides a reliable system that supports safe and efficient diving.
At its heart, DIR follows a simple idea: take only what you need, place it where it makes sense, and keep everything clean and streamlined. When applied correctly, this approach allows divers to move comfortably through the water while maintaining full control of their equipment and awareness of their team.
