The EdgeTech 4XXX series digital sidescan systems are manufactured by EdgeTech Inc., of Massachusetts and Florida. The 4100 offers dual-frequency (100 and 500 KHz) true digital data. It is the modern incantation of the classic EG&G-272. The 4200 offers 120 and 410 KHz data in either High-speed or High Resolution modes. The 4300 offers 410 or 270 KHz operation in high-speed mode, for surveys at speeds up to 10 knots.

OIC interfaces to all three sensors through EdgeTech's Discover software, which runs in the background in "server mode" on the same PC as GeoDAS-PC/ET4K.
Because all these systems also record data in their native
EdgeTech JSF format, OIC supports post-acquisition processing
and mosaicking of data from these systems via OICcleansweep.
