Which Humminbirds have dedicated down imageing crystals?

Could someone please tell me which units have the dedicated crystals for down imaging.

The simple answer would be any of the HB units that actually have "DI" in the model name....

Rickie

345c DI
385ci DI Combo
570 DI
596c HD DI
597ci HD DI Combo
788ci HD DI Combo

The Combo units mean that they come with a GPS Receiver, all of which are internal.
Those with a “c” after the numbers mean that they have a color display.

All of the SI units will do Down Imaging also :)

The SI units do not have a dedicated crystal though, but yes they do DI also.

Thanks for the info.
