The ST and DT line of wings are another brand new series designed for single or double cylinders. They feature a 360 degree tapered profile for standard and heavier cylinders, to increase lift towards the hips, promoting better horizontal trim in dive position while still allowing perfect surface floatation. While the DT45 Dual features a more consistent 360 degree floatation for lighter aluminum cylinders with a redundant air cell. Target audience for the DT45 dual is warm water, banded aluminum cylinders in a wetsuit where backup inflation is mandatory. While the DT50 is focused on the dedicated drysuit diver, with heavier cylinders in cold water.
