The MB-72 Buoy, when moored with BuoyTec's Elastic Mooring Array, provides the industry with pin-point accuracy for such critical tasks as pipeline and underwater hazard marking, dredged material management, and as guard buoys for underwater instrument arrays. The lateral movement of MB-72 buoys is limited to a radius of 5 meters, or less, in most coastal applications, which is an order of magnitude better than slack-moored systems.

Limited buoy roll and mooring "tilt" (usually less than 10 degrees for each) make the MB-72 System the ideal choice for surface mounted ADCP's and other environmental sensors. By maximizing Survivability and Accuracy, the MB-72 Buoy System provides marine invesigators with the Reliability necessary for Successful, Cost Effective programs, world-wide.
