The Apeks WTX D-18 Wing Single Tank is a compact donut-style buoyancy cell designed for divers who want streamlined performance with full modular flexibility. Originally developed for technical diving, single cylinder wings have become increasingly popular in recreational diving due to their balanced trim and stability. The continuous loop air cell design prevents dramatic air shifts underwater, keeping buoyancy evenly distributed from left to right. Built to integrate seamlessly with the Apeks WTX and WTX-D modular system, the D-18 allows divers to create anything from a lightweight travel setup to a more advanced technical configuration. A WTX single tank adapter is not required, keeping the system clean and efficient.
