Online's range of acoustic receiver systems, when used in conjunction with an acoustic pinger, provide a reliable means of tracking and locating a stuck pig in a subsea, liquid filled pipeline, resulting in substantial cost savings. The range of receivers also allow for detection of a signal from subsea warning beacons or alarm pingers.

The diverse range includes ROV and diver held solutions to suit various applications.

The receivers can be tuned to a wide range of frequencies, making them compatible with most other manufacturer's equipment.

• The 2405 receiver is a stand-alone, battery powered system that can be used by an ROV to locate subsea acoustic pingers.
• Directional hydrophone provides increased precision.
• Acoustic Signals are displayed as they are received - high brightness OLED display and LEDs that can be seen clearly by an ROV.
• The 2405 does not need to be interfaced with an additional piece of equipment other than an ROV camera making it, in relative terms, a straightforward method of receiving.
• Frequency controls can be manipulated subsea by ROV switch giving the operator full control without returning the unit to the surface.
