The chirp on sidescan makes this a really interesting product and it have the potential to get really good details even at longer ranges using 450kHz.
I've tried to find dimensions on the transducer XM 9 20 MSI T but failed so far.
If it has the same length as the LSS2 it would match the lobe width of the Lowrance at 450kHz.

The Lowrance suffer from not having chirp, as soon as you increase the range beyond 30? meters you lose a lot of detail probably due to increased pulse length.

Some screenshots made by a French fishing guide show the details you can get with this technology!











As the holidays approach if some want to be initiated or to try to fish in France I leave the link to his site:
