Yes I am using the TD from my Elite 7HDI. I swapped it out with Lowrance after I had problems with it. The HDS7 touch was a compatible swap, so I still have the TD along with the LSS2. I was so afraid on knocking the LSS2 off fishing some of our stump infested waters that I bought one of the clamp on transducer mounts from BPS to mount it on. I can raise and lower it to get it out of the water when needed.
