Helix 7 transducer question

Does anyone know is the XHS 9 HDSI 180 T an upgrade from the transducer that comes in the box with the Helix 7 Chirp SI GPS G2N? Thinking about buying one if its worth it??? I'm going to keep the transducer that came with the unit mounted on the trolling motor (because it was a pain in the butt installing it on a Terrova) and install a second transducer on a BowDucer outrigger from Fishing Specialties. To help reduce "swipe" when turning trolling motor. Any help would be greatly appreciated Thanks

I should also mention that I'm also looking at the Da-Ducer apparatus from Podunk from the second transducer

The Helix 7 SI models come with the compact version transducer. The HDSI transducer has longer crystals and can provide some improvement only in 455khz frequency. It is the same TD that comes with the non-MEGA Helix 10/12 SI models. BTW, the XHS and XTM versions are identical transducers but come with different mounting hardware and the TM version has a 15' cable vs 20' for transom.

Thanks ezfishin! You seem very knowledgeable on the subject of TD’s. What would you recommend to get the most out of my HB unit?

If you didn't want to replace the TD on the TM, then probably would do as you're planning assuming no install issues with the apparatus.

Here's a link from another forum showing the difference in the imaging:
