The Ultra High-Frequency Sonar Goggles (also known simply as "Sonar Goggles") are a new generation of goggles issued to Splinter Cells by Third Echelon that appeared in Tom Clancy's Splinter Cell: Conviction. They succeed the prototype Multi-Vision Goggles. The Sonar Goggles were used by Third Echelon Splinter Cell Archer, Voron field operative Kestrel, Sam Fisher, and other Third Echelon Splinter Cells during the Third Echelon Conspiracy.
