What is the speed needed for the Helix DI and or SI to work correctly?
The chart speed should match the speed your boat is moving. I normally have mine set at 3
In my boat, I get the best images at 4-5mph and my chart speed set to match my speed (4 or 5). I also have si at the bow and a chart speed of 1 to 2 produces good images while easing around with the trolling motor.
I asked the folks at Humminbird this same question. They said that at least 1.5 mph and faster to get good picture.
If I mount DI on trolling motor what is the lowest speed that will produce a good picture?
I have had DI on the bow for a long time and it has always worked well even when going at slow speeds. I now have SI up front as well, only had it out once but I was getting good SI images last weekend spider rigging at .6 to .8. I think you will be happy with the performance at low speeds. My unit is Mega Humminbird

I snicker to myself everytime I hear HB'S recommendation of imaging only works at faster speeds ...

I have di and 2 d at front and fish bp much,I can see the fish on di while I got TM on spot lock,it's always s mater of learning what your unit is telling you

I run mine on lowest speed on trolling motor and like 5 mph with 5 on unit for side scanning on main unit .
Mine works well enough at .4 MPH to show me shell cracker in the beds.

Nice pic.! The Megas really rock!
I am different when I run SI as I always am looking for fish and not structure, so I will run my SI scroll speed at 10 much of the time. For me this elongates fish marks and shadows, makes them easier to pick out. Once I find fish I may go back to match boat speed to scroll speed to better understand how and what they are relating to.
