Commercial diving isn't recreational — the kit reflects that. While the exact loadout depends on the job, there's a core set of equipment every commercial diver relies on to work safely underwater.
Diving Helmet or Full-Face Mask The centrepiece of any commercial setup. A hard hat diving helmet provides surface-supplied air, communication, and protection in demanding environments. Full-face masks are used for lighter work but offer the same communication capability.
Surface-Supplied Air System Unlike scuba, most commercial diving uses an umbilical — a bundled line carrying air, communications, and sometimes video feed from the surface. It keeps the diver connected and supplied throughout the dive.
Dry Suit Commercial divers work in all conditions. A dry suit with appropriate undergarments keeps core temperature stable in cold or contaminated water where a wetsuit simply won't cut it.
Diving Knife and Hand Tools Practical and safety-critical. A knife for entanglement risks, plus job-specific tools — cutting equipment, torque wrenches, hydraulic tools — depending on whether the diver is doing inspection, welding, or construction work.
Dive Computer and Depth Gauge Decompression management is non-negotiable. Accurate depth and bottom time tracking can be the difference between a safe ascent and a serious injury.
Communications Equipment Two-way comms between diver and surface supervisor are a legal requirement on most commercial jobs. Clear communication keeps everyone safe and the work on track.
