No, the 800 series and up come with the HDSI (Hi-Def) transducer. It has the addition of 800khz which has a thinner beam angle and gives better detail on the SI Images. However, the downsaide of the higher frequency is a reduction in range.
Also the transducer is largeer and the 455khz images on the HDSI transducers are just a little better than the 455khz on the Compact SI with the 700 series.
Hope that helps.
