I was wondering if the XP 14 20 and the XTM 9 20 T are essentially the same transducer? I have a XTM 9 20 T that I do not plan on using, but have been considering a through hull for when I run on a shallow river with a lot of sandbars. Can I just epoxy the XTM 9 20 T to the hull (it's fiberglass), and be good to go or do I actually need the XP 14 20?
Thanks,
CC
