Since its introduction, the new wideband and versatile EM 710 multibeam echo
sounder has gained considerable popularity among many different user categories.
Up until now, approximately 40 systems have been sold. Quite surprisingly, the model
with the highest specification of 0.5°x1° beam widths has become the most popular
model, making up about 50% of the units sold.
The extremely narrow transmit beam of 0.5° is a feature that results in very
high resolution of the survey results, and is required for detection of objects
according to IHO S-44 special order. Many users are waiting for the dual swath functionality,
in order to have the full system performance of their EM 710. This functionality
is expected to be distributed from May 2008 and will include new and more powerful
boards for signal processing.
