Mobilis DB 400-800 & FB 600-800
zone marking buoys

Hydrosphere offers a range of small buoys and floats manufactured by Mobilis that are designed for beach and protected area marking.

Managed zone marking and well-marked shore areas can significantly increase user enjoyment and safety - reducing potential user conflict and increasing physical protection through clear indication of usage, restrictions and hazards.

Mobilis zone marking buoys are available in cylindrical, conical or spherical shape and are constructed from rigid, high density polyethylene plastic (HDPE) with optional internal foam.

800mm and 600mm buoys are available to fit with a range of self contained solar powered lights, signs or topmarks.

Alternatively, Hydrosphere offer tailor-made signs for more bespoke applications.

Please contact us for more information on the full range and variations of buoys and signs available.
