    Can I change out the built in ultrex from di to si?

    My ultrex has mega di+, ide like to add 360 and change out the ultrex transducer to si. Is this possible? Also, can I set the graph to turn on automatically when the ultrex is deployed, kind of bugging me every time I stop/deploy the unit.

    thanks,
    Jeff

    If you get the MEGA 360 and connect it to the same unit that a SI transducer is connected to, you loose the SI function in the SI transducer.
    MEGA 360 replaces SI. The Minnkota MDI is a better choice and it is not +. The Humminbird G3N transducers are +.

    No you cannot set the Humminbird to automatically turn on or off.

    It is not recommended to change Mega DI to Mega SI. It is not cost effective if you are talking about doing the built in. External should be pretty easy.
