A Sonar, DI, or SI model will support the 360. Just choose whatever sonar technology you want with it.
The Helix 12 seems to be the best size for viewing 360.
There are MEGA SI models and MEGA DI models. The MEGA DI model has Dual Spectrum LowQ 2D sonar that has 140-240 kHz CHIRP range.
MEGA (1200 kHz) is another Imaging frequency to go along with 455 kHz and 800 kHz.
Sharper images with less coverage.
As far as a trolling motor is concerned, any motor that has an internal transducer is only for dual frequency 2D sonar. None do any imaging of any kind.
