I have a Helix 10 G2N.
If I use transducer XTM 9 MDI T on my TM, and hook it up to my Control head with Y cable 9 MDI SIDBY, will I be able to get Mega down from the TM by selecting the transducer from the sonar menu?
Will the Y cable throttle the Mega signal down to regular 2d ?
If so, how do I use the mega on the TM to get Mega Down?
Thanks
