UNSPSC 41115500: Sound generating and measuring equipment

UNSPSC 41115500 Sound generating and measuring equipment is a Class code covering specialized hydroacoustic and sonar instrumentation for fisheries assessment, bathymetric mapping, and aquatic research. State and local procurement under this code targets equipment for fish population surveys, seafloor mapping, and marine resource monitoring rather than consumer audio or general public address systems. Recent solicitations show demand from state wildlife and fisheries agencies for single specialized units—hydroacoustic echosounders, multibeam sonar systems, and associated navigation and positioning hardware—rather than volume purchases of commodity equipment. Issuing bodies are narrowly concentrated in state-level fish and wildlife agencies with direct operational responsibility for aquatic resource management and marine science research.

Recent activity concentrates in the Southeast and Mountain West. The Utah Division of Wildlife Resources (Department of Government Operations) posted a sole-source procurement for a BioSonics DTX-XT Autonomous Echosounder Surface Unit with a due date of April 28, 2026, valued at $75,000 and delivery required by June 1, 2026; the procurement justified sole-source award based on data continuity with existing monitoring programs and the sole domestic availability of compatible equipment following HTI's exit from the U.S. market. The Florida Fish and Wildlife Conservation Commission issued an ITB for a multibeam sonar system with integrated navigation and positioning capability for fisheries research in coastal waters, with sealed bids due April 16, 2026, at 4:00 PM ET and anticipated award on April 22, 2026; Addendum 1 was posted April 8, 2026. Both procurements demonstrate preference for equipment meeting exact technical specifications—frequency bands, beam configurations, cable lengths, mounting requirements, and proprietary software integration—and emphasize equipment compatibility with existing fleet or legacy data architectures. No recent activity in other states is supported by the source.
