This will probably be a little out there for most but its worth a shot as I got confused.

I just bought two new HB 587 ci HD di units. I am wanting to be able to use them this winter with an ice ducer that will let me use both 2d sonar and the built in flasher. My question is that I already have a HB ice35. Can I use the transducer from the ice35 on the 587 and still retain regular chart 2d sonar?
