I am trying to find a mega DI only trolling motor transducer for my Solix 10 G1. Is the XTM 14 20 MSI T the only one for the G1's that has mega DI? I show the XTM HW MDI T is only for the G2's. Am I right that the XTM 14 20 MSI T is the only option for DI on the trolling motor? I really don't need the SI, but this is the only one I show.
