The 859ci HD DI stock xducer (XNT 9 DI T transom mount) can be exchanged for the XTM 9 WIDE DI 20 T trolling motor mount ...

*XNT 9 DI T = 200kHz 16°/455kHz 25° 2d and 455kHz 75°/800kHz 45° DI
*XTM 9 WIDE DI 20 T = 200kHz 20°/83kHz 60° 2d and 455kHz 75°/800kHz 45° DI

Same DI piezo in both ... Different 2d piezos ...
