I am in the process of installing a Lowrance HDS 7 Gen3 on the bow of my new boat. With Lowrance I understand that in order to have 2D sonar and structure scan down scan and side imaging it requires two separate transducers. I have done some research to find a transducer that has both structure scan and 2D sonar built into one transducer that I could use to mount to my trolling motor. My question is will this work and if so what are some products that would do the job? Also I have one HDS 7 Gen3 mounted in my dash already for the back. I don't mind having two transducers for the transom. Will buy the hub to network the two units together.

I'm pretty sure that the Elite transducers have 2d sonar and down scan on them.  I have an lss 2 and 2d sonar puck mounted on my trolling motor.  Ethernet connection should be all you need for networking.

If you just want 2d and down scan, you can get the HDI transducer which has both. Then you can network with the dash locator and get side scan from your rear transducer. 

The Elite Ti with Totalscan transducer is an all-in-one transducer. Like a Garmin SV or Humminbird ONIX SI.

The HDS Gen3 has software that supports that transducer:

You do not have to settle for less than you want.

 

Thanks for all the help on the post guys!! I believe I will go with the TotalScan transducer on the trolling motor. Not overly worried about having side imaging on the trolling motor due to the fact that you have to be going a certain speed for it to work correctly. I'm used to hummingbird having an all in one transducer for my previous hummingbird 997. I am also under the impression that with the Gen3, the hub is not required to network between the two units due to wireless connection? Feel free to correct me if i am wrong.
