Thoughts?

Tilting the pole slowly back under the boat is a good idea: it will show everything what is in front of you in water column, and it will show bottom structure in front/below you in curved form though, but quite readable. I like this mode the most, but tilting the pole you will be limited in angle of tilting – if to tilt or better to rotate just a transducer you will be able to point it in front-down-back from +90 till -90 or for 180 degree. Then you will get pictures like I got on Humm 570 DI and Humm 385 DI units, which will show you what is directly under you and several depths ahead and behind.
These are pictures that I got three weeks ago without using a rotating mechanism, just slowly pulling the transducer cable up and down with hand, the SI transducer was suspended on white cable (rope):
