HDS 9 Gen 3 Transducer Ch 1 and Ch 2

[procraftpaul]

I have a fishing friend that recently purchased a HDS 9 Gen 3. I am trying to select multiple transducers so he can select the shoot thru hull transducer when he is on pad. I currently have a HDS Carbon 9 and have channel 1 and 2. Channel 2 is default for Totalscan. When I go into the Gen 3 I don't see a Channel 1 and 2. I can only select one or the other not multiple.
