The Tecline Donut 22 Special Edition is a high-lift annular wing designed specifically for demanding, deep technical diving in a twinset configuration. CE certified and approved for handling heavy setups up to 18+18 litres with the addition of up to 4 S80 stage/deco cylinders, it is the ideal choice for twinsets consisting of 2x10L, 2x12L and 2x15L.
This "Special Edition" version combines superb structural strength with cutting-edge geometry designed to optimise hydrodynamics, valve accessibility and trim stability even with significant equipment loads.

Advantages of the "Special Edition" Geometry:
-
Thin and Low Upper Profile: The wing features a flattened and narrow profile at the top. This design ensures a comfortable and secure head position and leaves ample space for first stages. Hoses make fewer bends and reach the front linearly, ensuring immediate access to valves in an emergency or during tests (valve drill).
-
Elongated Lower Profile: Being slightly longer at the bottom, the wing shifts the air's centre of gravity downwards. This results in a higher, more stable, and comfortable horizontal posture (trim), allowing for extremely efficient and precise buoyancy control.
-
Optimised Dump Valve: The lower left overpressure/dump valve is positioned on the outermost edge of the wing. This feature allows the diver to dump gas while maintaining a perfectly hydrodynamic and horizontal position, without having to raise the pelvis upwards.
-
Central Inflator Inlet: The corrugated hose connection is installed in the upper centre to ensure intuitive use and perfect symmetry in air distribution.
Target User:
The Donut 22 SE is positioned as one of the best technical wings on the market. It is the ultimate tool for technical, trimix, and exploration divers who use large-volume twinsets and multiple stage cylinders, and who demand total reliability, comfort, and impeccable trim in every situation.
