I just used an IP68 rated reverse camera with a 7” colour screen.
To give the camera the best chance I used sikaflex on the whole thing except the glass screen on the camera and for the most part I troll it ahead of my dredge and watch my spread. I didn’t use it this last season but I did the year before.
This is a screenshot taken from my phone of a video shot in full sunlight. When I’m watching it on the boat I can see lures working above it on the surface that are 20ish meters behind the camera and when a fish comes into the spread I see them a long ways away underwater. The dredge in this photo is 24” diameter. Prop wash on the left and chine wash on surface above and to the right.
That’s a completely different situation to what your doing though.
I have 40 meters of cable on this camera and have dropped it down to see things that interest me. No different to an aqua view like I used in Alberta.
