I presently have my GT mounted under the handle of a straight shaft that I purchased. I saw a picture where the person had mounted the sovereign meter on top of the inline probe box. I can't make out in the picture just how it was done. Obviously, my probe box will mount on the straight shaft via the "V" clip. Just how does the meter mount on the top of the inline?? Do I need to put another "V" clip on top of the inline box?? Can someone enlighten me??
