EM2040 MKII

By alternating between the frequency modes per ping, the system is capable of providing the operator with Multi Frequency Backscatter of up to 5 frequencies in a single pass. The same functionality allows the system to alternate between a full swath mode and a high resolution mode providing full coverage while maintaining ultra high resolution over a target. The angular coverage for the 200 and 300 kHz is up to 170° on slopes and piersides, with coverage up to 8 times water depth on a flat bottom. For a dual transducer system, 220° angular coverage or 10 times the water depth is achieved on a flat bottom.

The EM 2040 MKII is a modular system, fully prepared for upgrading to cater for more demanding applications. The basic system has four units: a transmit transducer, a receive transducer, a processing unit and a hydrographic workstation. The EM 2040 MKII receiver is 0.5° and is delivered with a 0.25° or 0.5° transmitter(s). The transmit fan is divided into three sectors pinging simultaneously at separate frequencies ensuring a strong and beneficial dampening of multibounce interference. As an option the EM 2040 MKII can be delivered with dual swath capability, allowing a sufficient sounding density to meet survey coverage standards along track while maintaining a high vessel speed.
