Marketing description: Why choose the DIR ZONE PRO 120cm buoy?
-
Excellent visibility in all conditions: The bright color and 120 cm height above water level ensure that it is easily visible even in rough seas and from a long distance.
-
Integrated small relief valve (Small OPV): Protects the buoy from bursting or damage as it rises from the depths and the air inside expands. The valve also allows for easy deflation after a dive.
-
Combined filling system: The buoy can be quickly and safely inflated from below using the Octopus/mouthpiece, or by connecting a medium pressure inflator hose.
-
Highest durability: Made of extra-dense, abrasion- and UV-resistant TPU-coated nylon with welded seams. Designed for intensive use in both freshwater and the salty and cold water of the Baltic Sea.
