Effective communication is critical in professional diving operations — from offshore inspections and underwater welding to subsea construction. Unique Group supplies a complete range of diving communication systems engineered for clarity, durability, and safety in demanding marine environments.

Our Range of Diving Communication Systems

• Wired and Wireless Systems – Reliable communication between surface and divers through hard-wire or acoustic wireless technology.

• Surface-to-Diver Units – Multi-channel intercoms and communication panels for surface control stations.

• Diver-to-Diver Systems – Compact and rugged underwater comms enabling seamless team coordination.

• Integrated Communication Solutions – Designed for commercial diving spreads, supporting multiple divers simultaneously with superior signal strength.

These products are trusted across the medical, defence, commercial diving, and oil & gas industries for their ability to perform under pressure.

Key Advantages

Our communication systems are built to perform under pressure — literally. Each system is tested and proven to deliver clear, uninterrupted communication in the most challenging subsea environments.

• Crystal-Clear Audio: Advanced noise-reduction ensures uninterrupted communication in noisy subsea environments.

• Enhanced Safety: Maintains constant link between surface control and divers during critical operations.

• Operational Efficiency: Supports quick decision-making, improving productivity and reducing downtime.

• Built for Harsh Conditions: Corrosion-resistant, depth-rated systems tested to international safety standards.

Applications

Our diving communication systems support a wide range of commercial and offshore diving operations, including:

• Underwater Inspection and NDT Activities – Maintain reliable voice contact during ultrasonic thickness measurement, visual inspection, and subsea integrity assessments.

• Subsea Construction and Maintenance – Ensure efficient coordination between divers, surface teams, and crane operators during installation or repair work.

• Salvage and Recovery Operations – Facilitate real-time diver communication and safety management during heavy-lift or debris-removal operations.

• Offshore Inspection, Maintenance, and Repair (IMR) – Provide continuous communication for multi-diver setups across complex offshore projects.

• Commercial Diving Training and Safety Drills – Support instructor–diver communication and emergency response readiness.

Frequently Asked Questions

What do divers use to communicate?

Divers use various communication equipment depending on the nature of their dive. For underwater communication, divers often use full-face masks equipped with built-in communication systems that allow voice transmission through a wired or wireless connection. Surface-supplied divers might use hard-wired communication systems, while those on scuba might use through-water electronic communication devices. Additionally, simple non-verbal tools like hand signals and writing slates are commonly used for basic messaging.
