I've followed the various messages on the Lowrance X-15 MT dual freq. transducer, but I've never noticed anyone compare the virtues of the dual freq/cone angles to the advertised advantages obtained with the Vexilar Edge (Lowrance 12 degree 200 khz/37 degree 50 khz and Edge 10 degree 400 khz/38 degree 100 khz). Now granted, I believe all things being equal the 100/400 khz combo should provide better discrimation than the 50/200, and perhaps moreso in shallow water, given the significantly lower power output of the Edge. Perhaps the 4000/8000 watts of the X-15 200/50 khz is too powerful for shallow water use as per the Edge ie. localizing/coarse tracking of countours with the 100 khz beam, and fine tracking with the 400 khz beam.
Vexilar recommends colocation of the two transducers included with the Edge to provide just such a wide/narrow view of the same patch of water; as for the Lowrance transducer, ya can't really get more colocated, so the theory should be just as valid. Unless operating this way is undermined somehow by the frequency and power output design decisions of the X-15?
Anyway, does anyone have an opinion on this? Thanks,
Joe
