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.

Make sure you are running the latest software version and you have selected 'Network Sonar'.

There is no Ch1 and CH2 on a Gen-3
You choose the source in the sonar menu under source
