| DLS-1 is a self-contained, high-performance device for use in detecting large and small underwater objects. This hand-held sonar is effective in detecting sunken vessels, lost equipment, downed aircraft, and other submerged objects.
DLS-1 has been particularly effective in locating downed aircraft and in localizing and retrieving the damaged parts necessary for a successful accident investigation and reconstruction. DLS-1 has been a valuable search and recovery tool in major, high profile accidents, such as TWA 800 and Swissair flight 111, as well as recent general aviation accidents off of both the California and New England coasts.
This compact, lightweight unit can be operated by a diver using one hand. It features a pole-mount interface, as well, for over-the-side operations aboard ships and small launches.

| The unit functions to depths of 91 meters (300 feet) and has an operating range in excess of 2,000 meters (2,180 yards). It has both active and passive modes of detection. The DLS-1 is a commercial derivative of the AN/PQS-2A, a non-magnetic diver's sonar manufactured by Harris Acoustic Products for the U.S. Navy.The broad bandwidth generates improved range detection in the active mode (CTFM, Continuous Transmission Frequency Modulated signals) -- and in the passive mode facilitates operation with a greater number of pinger types. |
