This is our ultra heavy duty fish finder control screen mount.  However rough things get and however large and heavy your fish finder conrol screens are, this will handle it as long (as you mount everything correctly of course).  Put on as many screens as you can fit.  Fish Finder Screens need to be 9 inches and above.
 
We recommend no more than 2 screens per every 2 feet of height due to size of screen constraints.
