Rickie, I think the 2D & DI are in the same transducer. I also think you have to add a black box(like Lowrance) to get SI.

This is the supplied transducer with the 70DV. https://buy.garmin.com/en-US/US/shop...-12087-01.html
This is one more picture of the same steel structure in SI mode. Actually the depth is about 20ft only against your 60ft, water is clean and no waves at all. Hope the CHIRP will give us much more opportunities.

great pics and I can't wait to see some form somebody who has the si chirp.
I found a pic of the Garmin SideVu xducer...
If the 2d and DI are in the stock xducer...and the SideVu is added with the additional black box...I wonder why this xducer also has a DI piezo...??
Maybe this xducer CHIRPs the SideVu and the DownVu...while the stock xducer is conventional 2d/DI tone burst...:dono (I'll have to read more to get confirmation)...

The SI ducer has DI, but no 2D. In my case, with a 70DV, I have to keep the 2D/DI transducer in order to have 2D sonar, if I install the black box and SI/DI Chirp.
