I’m shopping for a new TM and have not decided which model to get. Is the transducer that’s built into the Terrova good enough to use with a Helix? I have a Mega unit at the console and don’t currently have a unit at the bow but I will get one soon. If the TM trans isn’t good enough for the Helix is there a slot on the Terrova to run the cable in for the transducer? If not on the Terrova, how about on the Ulterra?
