It is a hub with 3 ports that has chirp. It adds chirp to the touch. yes.

I talked to Airmar. They said it helps with target seperation in shallow water.

I am currently using LSS1 as a 3 port hub only for the 2 touches and a gen1 hds. Just got another Touch, so I will ad the hub at a later date. I now have 4 hds on my pondtoon. Plus, I have 1 HDS 2d only unit to put somewhere. You will see it sooner or later.
