Looking to get a trolling motor transducer for my cable steer motor. Question is what is the difference between the XTM 9 DI 25 T and the XTM 9 WIDE DI 20 T? Which is better? Pros and cons??

Reason for this is... I use a Terrova when spideringing and the transducer don't really face any dangers....but I swap over to a cable steer when jig fishing and learned to buy the transducer made for a trolling motor mount application after breaking them off on stumps a few times.
