This was a long time coming (6.5 seasons since rigging my 2013 Fishmaster) due to the space requirements and desiring nothing blocking my view straight ahead for the driver. I tried a standard size I-Pad that was my son's when he upgraded to the big I-pad a year ago and just didn't like the weight of it and it's size and no place to mount it.
This Samsung Galaxy 8" 2018 version is light and fits the bill. I ordered off Amazon a flexible arm to hold it that screws by bracket into the side. So I can now go full screen on my HDS-7 Lowrance for sonar.
The last photo is where my probe and weight was located 10 days ago and recovered off Split Rock:
