Kongsberg EM 304 MKII Multibeam Echo Sounder

Kongsberg Maritime launched the

EM 304 MKII, the newest addition to its portfolio of deep-water multibeam echo sounders.

Underpinned by a new KONGS-

BERG-designed wideband transmitter working in the 20-32kHz band with a nominal frequency of 26kHz, the new mapping system signi? cantly improves upon the performance of the MKI model, boosting range from a previ- ous maximum of 8,000m to full ocean depth, and increasing swath perfor- mance by up to 75%.

In addition, the EM 304 MKII deliv- ers 0.3° x 0.5° resolution. Meanwhile, the system’s modular construction and ? exible transducer design make instal-
