  • Virtually eliminates vortex shedding effects which are inherent with spherical flotation.
  • Substantially reduces mooring excursions and inclinations.
  • Significantly improves instrument depth keeping characteristics.
  • Self-compensating for mooring inclination and flow direction.
  • Supplied complete with mooring attachment point and instrument guard.
  • Unmatched stability provides an exceptional moored instrument platform.
  • Reduces the potential for measurement errors associated with mooring movement.
  • Reduces buoyancy requirement due to lower frontal area of flotation.
  • Purchasers can utilize their existing Viny Floats/Glass balls or we can supply buoyancy.

ADCP BUOYS – Models A2 & D2

An improved mooring system for ADCPs and other oceanographic instrumentation.

Mounting ADCPs or other instrumentation in a streamlined buoyancy package reduces the variability caused by mooring oscillation typical of spherical flotation.

Few instruments have the capability of segregating mooring movement from actual data.

Reduced mooring movement decreases instrument data noise.

Reduced mooring movement has applications in acoustic, optic, magnetic, and other moorings.
