Elite 9 touch screen
Boat, Lund deep V
Outboard Merc 115 4 Stroke
Problem— graph on, outboard on or off, not moving— all good.
Boat underway, screen clouded over with vertical lines, faster speed, closer the lines until graph is unreadable.
Problem—- it doesn’t do it all the time. One day he ran boat WOT and the graph was fine, an hour later it acted up again.
My thought is it is turbulence from the prop, cavitation from the boat. But why wouldn’t it be consistent?
Your thoughts?

All aluminum hulls produce too much cavitation and sonar cannot read through any kind of air bubbles aka cavitation (science not product malfunction).
Transducers should be mounted on the starboard side of any boat too.
The amount of weight in the boat will also make a huge difference on these hulls.
Lots of gas and lots of weight? Transducer is too low.
Light load, the transducer may be too high.
No load it may be too high.

Transducer is on starboard side.
Like I mentioned, it will work fine under power, 10 minutes later it won’t. The load didn’t change. Same guys, same gallons of gas ect. This is the mystery

Check the VOLTAGE with EDIT OVERLAY on a screen.
Let's see what the machine gets from the battery when the boat is on plane.

I know this reply doesn't address the question, but I just wanted to point out that my transducer is mounted portside-factory mounted by Tracker Marine-and does fine even at speed. I'm not sure sure why, but why would I fix what ain't broke? Sorry for the tangent.
