Yes the Hbird transducers do have a kick up bracket on the transducer mounting plate. Depending how you want to set up your ducers the larger SI transducer can work at high speed at least on mine in 2D it will read up to 50 mph GPS. This year I switched up and went to the Y cable and a separate 2D transducer that way I raised up my SI transducer to keep it out of harms way, as stated can be set up either way.
SI transducer has to have a clear view with no obstructions to both sides of the boat, I do have to tilt my big motor up a tad to get my left side SI to read properly.
