    Anything new in downscan?

    Seems like this technology has fallen behind SI. Other than the gt56 all the transducers stuck at 800khz. Id really like to see a COMPACT Mhz transducer with downscan only or downscan and 2D.

    Or is there not much to be gained from 800khz to 1.2mhz?

    As frequency increases, power has to increase too because signal loss increases rapidly.

    ETA: Just recalling numbers when I worked with seawater transducers, maybe something like a few thousand times more losses at 1200 vs. 800KHz

    If you have integrity, nothing else matters. If you don't have integrity,
