837B multi-beam echo sounder is IMAGENEX introduced a new generation of electronic multi-beam echo sounder, specifically for use in shallow water depth of 60m water depth measured multi-beam echo sounder transducer is small, portable applications, no large-scale multi-as complex beam echo sounder bulky deck unit, ideal for customers aquatic reef fisheries sector do put in place the site investigation, after laying reef topography measurements. 

Multi-beam technology has the advantage now widely used in the field of surveying and mapping, as opposed to the past, large and expensive multi-beam echo sounder, 837B with a compact multi-beam echo sounder transducer to be small, portable installation, convenient transportation and low cost very suitable for small survey vessel, to meet domestic ports, terminals, inland waterways and bathymetry dredging measurement requirements, is the world's most cost-effective electron multi-beam echo sounder.
