Trident Below Water Sub Duck BCD Signal Device
The Standard Sub Duck is for all standard Power inflators on most BCDS.
This is a perfect addition for a scuba diver who wants to be able to signal a buddy or dive boat above or below the surface. The Sub Duck by Aquatec is a perfect addition for standard bcd's such as Oceanic, Sherwood, Genesis, Tusa, Scubamax, IST, Cressi Sub and more.
This will not work on the Seaquest, Aqualung or Apeks and Scuba Pro BCD configurations, or added air installations such as Air XS, Air 2 style alternate air second stage/bcd lp configurations.
