All R2Sonic Multibeam Echosounders support TruePix™. TruePix™ is a unique functionality developed by R2Sonic that has the benefit of simultaneously reporting backscatter and water column data. The exclusive TruePix™ format delivers highly compressed water column imagery data (1% of traditional water column files), which enables real time water column data processing. In addition, TruePix™ returns amplitude, range, and angle for each target, which ensures unmatched accuracy. 

Multispectral TruePix™ consists of combining the capabilities of TruePix™ with R2Sonic’s proprietary multifrequency mode. In multifrequency mode, surveyors can ping at up to 5 different frequencies in a single pass. The intensity of the acoustic response for each frequency is different depending on the type of target in the water column. 

Being able to survey at up to 5 frequencies in one pass and with a single MBES presents several advantages:

• It increases productivity
• It reduces the costs associated with traditional multi-frequency surveys that require either multiple MBES or multiple passes
• All 5 frequencies have the same grazing angle, which increases uniformity, accuracy, and precision.

With Multispectral TruePix™, scientists can compare responses and discriminate between the different elements in the water column. This is a new area of research.
