Apeks Backmount Twin BC System

The Apeks Backmount Twin BC System is a purpose-built configuration designed for divers who demand stability, durability, and precise buoyancy control when diving twin-cylinder setups. Combining two proven Apeks components, this system delivers a balanced, highly customisable platform suited to technical diving, advanced recreational profiles, and demanding environments where reliability is critical.

At the core of the Apeks Backmount Twin BC System is the Apeks WTX Deluxe Harness paired with a stainless steel backplate. This harness is engineered to handle the weight and demands of fully rigged twinsets while maintaining comfort and load distribution both in and out of the water. The continuous webbing design offers exceptional strength and simplicity, allowing divers to configure hardware placement to their exact preference. Stainless steel D-rings and retainers provide secure attachment points for accessories, stage cylinders, and technical equipment, while the heavy-duty waist buckle ensures a solid, dependable closure. The included stainless steel backplate adds inherent ballast, improves trim, and provides a rigid foundation for twin-cylinder stability.

Matched to the harness is the Apeks WTX-D40T Twinset Wing, developed and tested by experienced technical divers. Its donut-shaped design allows air to move freely around the buoyancy cell, delivering consistent trim regardless of diver orientation. The wing’s refined profile distributes lift evenly and minimises unwanted air migration, resulting in excellent underwater stability. Curved side panels help maintain a streamlined shape, while the optimally positioned high-profile dump valve allows efficient gas release without compromising body position or trim.

The wing is constructed with an outer shell of 1000D Armorshield Cordura, offering excellent resistance to abrasion and cuts in demanding dive environments. Inside, a robust urethane bladder ensures long-term durability and reliable buoyancy performance. Practical details such as large drain grommets and a centre mesh drain panel aid water drainage and drying between dives, while the foldable centre section improves packability for travel.

Together, these components form a cohesive backmount twin system that reflects Apeks’ commitment to functional design, premium materials, and real-world diver feedback. The Apeks Backmount Twin BC System provides a strong foundation for divers looking to build or upgrade a serious twin-cylinder configuration while retaining the flexibility of the Apeks WTX modular ecosystem.
