Trying to understand my beamwidths. Below is the descriptions from HB for the same transducer.
(XT 14 20 HDSI T) HD SI, HD DI, Dual Beam, 20/60/90/180 degrees- 200/83/455/800khz
(ONIX) HD SI, HD DI, Dual Beam, 20/60/75/45/(2)86/(2)55 degrees- 200/83/455/800khz
What degrees corresponds with which khz?
