There is benefit to either TM puck ...

*XTM 9 Di 25 T has 455kHz 16°/200kHz 28° 2d cone shaped beams = narrower cones for better target separation ... especially separating fish from bottom detail ...

*XTM 9 WIDE DI 20 T has 200kHz 20°/83kHz 60° 2d cone shaped beams = wider cones for more coverage area ...

The DI is identical in all 3 HB dedicated DI xducers ...
