Many competitive sonar products commonly use post processing software
to “enhance” the arching effect produced when suspended targets enter
and leave a sonar beam. This additional processing can slow down
performance and exaggerate the information displayed. Humminbird’s
TrueArch™ Technology utilizes parallel processing of sonar data to
eliminate unwanted interference and noise and reveal unaltered sonar
echoes resulting in true arches of fish targets. This helps anglers more
quickly discern the size and depth of fish targets.
