I just purchased a Humminbird HELIX 9 CHIRP DI GPS G2N. I will need to swap out the transducer with Humminbird to a trolling motor version and I noticed there are 2 to choose from. One is a XTM 9 DI 25 T and the other is a XTM 9 WIDE DI 20 T. It will be used while spider rigging for crappie and I won't be in extremely deep water. Any info I need to make this decision easier would be greatly appreciated.
XTM 9 WIDE DI 20 T ...:
*200kHz 20°/83kHz 60° 2d conical beams
*800kHz 45°/455kHz 75° DI fan beams
-----
XTM 9 DI 25 T ...:
*200kHz 28°/455kHz 16° 2d conical beams
*800kHz 45°/455kHz 75° DI fan beams
------
The wider 2d beams in the XTM 9 WIDE DI 20 T will give more coverage under your boat ...

I think I'm leaning towards the WIDE transducer. Plus there is no extra charge to swap to it.
