Mares Diver Alert Surface Marker Buoy

  • Mares Diver Alert Surface Marker Buoy

Mares Diver Alert Surface Marker Buoy, We don't want to lose even a single diver!  That's why Mares' multi-purpose Divers Alert emergency marker buoy offers the very latest development in signaling devices to provide greater safety, even in the most extreme conditions. 
The Divers Alert marker buoy is distinctive because it combines the properties of different types of buoys into a single buoy model that is easy to use:  for marking your own position, for example, once you reach your decompression stop, this model can be inflated effortlessly underwater using the octopus.   Thanks to a duck valve on the bottom end, the air cannot accidentally escape, as often happened with classic decompression buoys.  The buoy holds its shape in all conditions and ensures that the diver's position will be signaled, even in adverse conditions, with its sizeable length of 180 cm.  This quality makes the Divers Alert emergency marker buoy useful as an ordinary marker buoy as well.  No air, no problem! The new buoy is equipped with a manual emergency dump and an oral inflator the diver can use to inflate it on the surface even if the tank is empty.  At the same time, the air dump valve allows you to quickly stow this large-volume buoy.

The Divers Alert emergency marker buoy has different colors on its sides: light orange and warning yellow are the colors that appear best at different times of day, under varying weather conditions, because they contrast with the water and with reflections and are consequently visible at great distances.  It's made of especially rugged PVC, reads "diver below", and also has a flag, in conformity with national and international specifications.  Particularly during night dives, the reflective strips placed high on the sides and the tab provide an additional crucial means of illumination – available separately (like the Marker Beam flashing torch stick).


  • 180cm tall and 15cm wide for high visibility
  • Solar reflective tape
  • Automatic seal system
  • Oral inflation connector for lp bcd hose
  • Pressure release valve
  • Dedicated pocket for light
  • Stainless steel d-ring
