I have a Carbon 12 with AT on bow of my boat. I only have the AT transducer in operation on that unit. It is mounted to TM shaft as that and mapping are all its used for. Does the AT transducer show water temp? My old livescope transducer did. If AT does, how do i get it to show on the Carbon 12 unit? I have looked through the settings and cant see that it reads Water Temp.
