DIR.
DOING IT RIGHT.

Every product AQUANAUT designs starts from a single question: does this make the dive better? If the answer is no, we remove it.

What is DIR

The philosophy that
made comfort a science.

DIR — Doing It Right — is a diving philosophy developed in the cave diving community and refined over decades of real-world use. Its core principle: every piece of equipment in its correct position, every configuration standardised, every redundancy eliminated unless it genuinely improves safety.

The Hogarthian configuration — named after William Hogarth Main — is DIR in practice. Backplate. Wing. Harness. Nothing more. Read the full Hogarthian Configuration Guide.

Organisations like GUE (Global Underwater Explorers) and UTD (Unified Team Diving) have codified and teach DIR at all levels — from recreational to cave and rebreather diving.

THE SIMPLEST
SETUP DELIVERS
THE BEST DIVE.

When your equipment configuration is standardised and minimised, you stop thinking about gear and start diving. That mental shift is the real benefit of DIR.

DOING IT RIGHT.
EVERY DIVE.
WITHOUT EXCEPTION.
Core principles

Five ideas that
change everything.

01
Streamlined configuration
Everything clipped, nothing dangling. A horizontal profile reduces drag by up to 40% compared to a typical recreational setup. Less effort. Less gas. More bottom time.
02
Backplate and wing
Buoyancy behind you, not around you. The wing inflates behind the diver's back, keeping the centre of buoyancy aligned with the centre of gravity. Natural horizontal trim. Read: Backplate & Wing for Beginners.
03
Standardised team configuration
When every diver uses the same layout, anyone can assist anyone else in an emergency. D-rings in the same positions. Valves in the same positions. Emergency response becomes automatic.
04
Minimum required weight
DIR divers use the minimum weight required for neutral buoyancy at dive end. Not a gram more. Over-weighting forces over-inflation of the BCD — destabilising trim and wasting gas.
05
Continuous education
DIR is a commitment to practising skills, refining configuration, and maintaining fitness. The best DIR divers are always improving. GUE Fundamentals is the entry point for most divers.
06
Team diving mindset
DIR is fundamentally a team philosophy. The dive team moves together, stays in visual contact, shares gas resources. Two divers working as a system are exponentially safer than two individuals.
BACKPLATE.
WING.
NOTHING MORE.
DIR applied to VOYAGER

VOYAGER is DIR
from the ground up.

We did not add DIR principles to an existing design. We started from DIR principles and built VOYAGER around them. The air volume geometry was calculated to place buoyancy at the correct position for horizontal trim. The D-ring placement follows UTD and GUE standard configurations. The weight system integrates directly with the backplate.

Backplate + Wing
Buoyancy exactly behind you. Perfect neutral trim. Natural horizontal position without fin compensation.
Zero dangling hardware
Every D-ring is there for a reason. Clean profile, less drag, effortless movement.
Team-ready
Standardised GUE/UTD configuration. Every diver on AQUANAUT gear is immediately readable to their team.
DIR IS NOT A CERTIFICATION.
IT IS A WAY OF THINKING
ABOUT DIVING.
DIR for recreational divers

You don't need a cave
to dive with precision.

The entry point is a GUE Fundamentals course or a UTD Essentials of Rec Diving — both recreational-level programmes available worldwide. After one of these courses, most divers say the same thing: I wish I had done this years ago.

The VOYAGER BCD is built to support this transition. You don't need to commit to technical diving to benefit from a Hogarthian configuration. Also read: DIR Diving Explained and the Beginner's Guide to Backplate & Wing.
