Digital Sidescan Sonars / Edgetech 272-ACI
The EG&G 272 dual frequency (100 and 500 KHz), analog sidescan was originally manufactured by EG&G Marine Instruments of Wareham, MA. EG&G Marine Instruments is now doing business as , with offices in Massachusetts and Florida. While the 272 is no longer in production, EdgeTech has released an Analog Control Interface (ACI) Kit consisting of a towfish interface box and PCI interface card, which allows GeoDAS to directly control the 272 as if it were a true digital sonar.
Through GeoDAS-PC/ACI the system can produce either 100 or 400 KHz digital sidescan data at 12-bit dynamic range, 24KHz sample rate.
OIC supports the EG&G 272-ACI sidescan (digital output) via GeoDAS-PC, providing a full control, logging and real-time processing solution. Logging the 272-ACI data as digital OIC records allows post-acquisition processing and mosaic productions with GeoDAS-Desktop or OIC CleanSweep.
