The 2405 Acoustic Receiver system is a standalone, battery powered, acoustic receiver system, tuneable to all frequencies between 8 kHz and 50 kHz which can be used by an ROV for tracking and locating underwater acoustic pingers

The system consists of a 2405 unit and directional hydrophone. Acoustic signals are displayed as they are received by the 2405 unit on a 2.7” graphical display and three high brightness LEDs positioned below the display.

Key Benefits

• Capable of detecting acoustic transmissions over distances of several kilometres
• Directional hydrophone provides increased precision
• Does not need to be interfaced with an additional piece of equipment other than an ROV camera viewing the display; making it, in relative terms, a straightforward method of receiving acoustic signals
• Frequency controls can be manipulated subsea by optional ROV switch giving the operator full control without returning the unit to the surface
• Minimal setup required ensuring time is not lost setting up multiple parameters
