your sechi dish looks like mine. I made mine. If anybody wants to make their own... The bottom of a 5 gallon plastic bucket is the exact size you need. Tape it off and paint,drill a hole in center and install a I-Bolt. Tie a white cord to it and mark each inch with a majic marker. At the 1,2,3,4, ect. marks I put a easy to see yellow zip tie on the line. Works great for me.
