Aye yi yie, if he buys a SONAR HUB he can get chirp sonar. He has no reason for that lss module, side imaging is already built into his graph head.
Do not buy that structure scan module and think that you’re going to get chirp, the guy above is giving you wrong info.
This is what you’d have to have for chirp on a gen 2. But it will not give you side imaging and chirp, it only does one or the other! Again, if you want chirp you are better off getting a gen3.http://www.lowrance.com/en-US/m/Products/Sonar/SonarHub-Sounder-Module-en-us.aspx
