C4 D&D Deep and Dynamic – Hydrodynamic Neck Weight for Freediving

The C4 D&D Deep and Dynamic is an innovative neck weight designed for freediving, specifically for dynamic and deep diving. Its hydrodynamic design ensures an optimal position in the water and reduces drag, allowing for more efficient movement.

Thanks to its modular weight system, you can precisely adjust the load to optimize your performance in the pool or deep diving. The ergonomic fit provides maximum comfort, while the durable material ensures a long lifespan.

Advantages of the C4 D&D Neck Weight

• Hydrodynamic design – Reduces drag and improves body positioning
• Modular adjustable weight – Customize the load to fit your needs
• Ergonomic fit – Maximum comfort without pressure points
• Durable & robust – High-quality materials for maximum longevity
• Ideal for pool and deep diving – Versatile for all disciplines

Configuration for Deep Diving

The neck weight is made of a lead alloy coated with comfortable thermoplastic rubber. The base weight is 910 g and can be adjusted with five interchangeable lead inserts on each side (40, 50, 60, 70, and 80 g). This allows the total weight, including metal components, to reach up to 1,630 g. Alternatively, the lead weights can be replaced with lightweight plastic components, reducing the total weight to just 1 kg. This variable weight system allows for adaptation to different wetsuit thicknesses and diving conditions throughout the year.

Configuration for Dynamic Disciplines

For dynamic freediving, where a higher weight is often required, the base weight can be supplemented with additional segments. These weight segments match the DYNO models and use the same secure fastening system at the back. This allows the total weight to reach up to 5 kg while maintaining compactness and comfort.

Available Configurations

The C4 D&D Deep and Dynamic neck weight is available in three standard configurations:

• Constant Weight Collar – Optimized for deep diving
• Constant Weight Collar + 4 rear segments – Total weight of approximately 3 kg
• Constant Weight Collar + 5 rear segments – Total weight of over 4 kg

Freedivers who start with the base configuration can later purchase a 4-segment set to reach a total weight of 3 kg or choose DYNO segments of 290 g or 1 kg to further increase the weight.
