DLS-3 Explorer is a diver operated hand held sonar specifically developed by Harris for use by Public Safety Divers. It is a self-contained, high-performance device for use in detecting large and small underwater objects. This hand-held sonar is effective in detecting submerged vehicles, drowning victims, firearms, and other submerged evidence. 

DLS-3 incorporates the same acoustic transmit and receive technology as the widely used AN/PQS-2A military sonar and the DLS-1 & DLS-2A commercial sonars.

The DLS-3 is mounted in a rugged Pelican housing that is at least 50% smaller than any other diver held sonar. The two operating ranges of 20 and 40 yards have been optimized for use in cluttered underwater environments in lakes, rivers and near-shore ocean locations.

The DLS-3 transmits at a higher frequency than other CTFM (Continuous Transmission Frequency Modulated) sonars which improves its ability to detect smaller targets.
