You can use the built-in transducer on your MinnKota but the down imaging won't work. You have to use the transducer that came with the Hbird to use the DI but on the positive side, when using the MinnKota ducer, everything else will work fine! Hbird makes a box and switch to link everything together so you can swap between ducers also. Check out their website. Good luck and Good fishin' - OH
