Cmax CM2

“The CM2 towfish incorporates dual frequency operation, with a choice of two configurations, DF (100/325kHz) and EDF (325/780kHz). For general survey tasks DF towfish are often the most useful. In 100kHz mode the search swath is up to 1000m wide, useful for searching for larger objects such as wrecks or freight containers. In 325kHz mode it is usually possible to distinguish such objects as mooring ropes, anchor chain, anchors, scour marks, pilings, crab pots, rocks (down to the size of a briefcase or less), as well as differences in seabed texture. EDF towfish offer the highest resolution. Like the DF towfish they offer 325kHz operation out to 150m. The EDF’s 780kHz frequency gives the most detailed images, very useful for positively identifying an object first located at 325kHz.
