This plastic backplate has been specifically designed for divers looking for a lightweight and practical way to carry small scuba cylinders.
Compatible with 3L, 5L and 7L scuba cylinders, it provides a secure and comfortable carrying system while significantly reducing overall weight and bulk compared to a traditional BCD.
The complete harness is assembled and tested by Best Divers using high-quality materials selected to provide durability, comfort and long service life.
Unlike a traditional buoyancy compensator, this plastic backplate is designed exclusively to support the scuba cylinder.
Its minimalist construction eliminates unnecessary components such as an air bladder, inflator or dump valves, resulting in a lightweight system that requires virtually no maintenance.
This makes it particularly suitable whenever a compact scuba configuration is preferred over a full BCD.
The fully adjustable shoulder straps allow the harness to fit divers of different sizes comfortably.
Quick-release buckles make the system easy to put on and remove, while the adjustment buckles allow precise customization of the harness.
Once adjusted, the harness maintains its settings, allowing the diver to wear it repeatedly without additional adjustments.
One of the distinctive features of this harness is the presence of integrated weight retainers positioned on the shoulder straps.
These retainers help prevent unwanted webbing movement, maintaining the chosen adjustment and improving cylinder stability throughout the dive.
The result is a more secure and comfortable fit, especially during extended underwater use.
The adjustable cylinder strap has been designed to accommodate the most common small mono cylinders used in compact scuba configurations.
The same harness can therefore be configured with 3L, 5L or 7L scuba cylinders, allowing divers to choose the balance between size, weight and breathing autonomy that best suits their needs.
The ideal cylinder depends primarily on the required breathing time, available storage space and overall equipment weight.
Compact cylinders are particularly appreciated whenever portability and ease of handling are priorities.
This plastic backplate can be configured with different cylinder capacities depending on the intended application.
The choice mainly affects overall weight, equipment size and available breathing autonomy.
| Cylinder | Material | Compactness | Weight | Air Capacity | Recommended Use |
|---|---|---|---|---|---|
| 3 L Cylinder | Aluminium | ★★★★★ | ★★★★★ | ★★☆☆☆ | Compact scuba systems, service diving, underwater inspections and applications where minimum size and weight are required. |
| 5 L Cylinder | Steel | ★★★★☆ | ★★★☆☆ | ★★★☆☆ | Longer underwater operations while maintaining a compact overall configuration. |
| 7 L Cylinder | Steel | ★★★☆☆ | ★★☆☆☆ | ★★★★★ | Maximum breathing autonomy for extended service diving and underwater maintenance. |
The 3-litre aluminium cylinder is probably the most popular choice for this harness. Its extremely compact dimensions and lightweight construction make it easy to transport and store, even where onboard space is limited.
For divers requiring longer breathing time, the 5-litre and 7-litre steel cylinders provide increased air capacity while maintaining excellent stability thanks to the robust harness design.
The harness is supplied complete with shoulder straps, waist belt and adjustable cylinder strap.
It can easily be combined with the most suitable components to build a compact scuba configuration according to individual requirements.
The modular design allows the diver to select the cylinder size and accessories best suited to the intended application, creating a lightweight and reliable compact scuba system.
