The tethered spherical 4-metre Au-2 balloon has been in great demand for the last decade. It is recommended for use in built-up urban areas at a relatively low altitude up to 30 metres. The Au-2 is a low-cost aerostatic advertising carrier for highly effective advertising campaigns in the busy thoroughfares of the city.

This tethered balloon has the aerodynamic shape, rigid empennage, and constricting volume compensating system. As an advertising carrier, it is recommended for use in places surrounded with large trees and bushes, in confined areas of city historical places of towns, and indoors.

This is the best aerodynamic aerostat with increased wind-resistance for long-term operation (up to 6 months) in any weather.

These balloons of aerodynamic shape with rigid sail-like empennage may be regarded as universal aerostatic multipurpose platforms.
