The X-67 Adaptor Plate can be added to any current or older Sonic Ice Hopper. All that is required is to drill two small 5/32 (.156) or 11/64 (.172) holes for the two 8-32 screws provided. Simply place the plate on the flat bottom surface of the of the front V shaped bracket and use it as a template for drilling. The Adaptor Plate's hole pattern will fit your X-67 and many other smaller Lowrance graphs that use this same base.
