WOW !!! this just may be the answer to my question. From the photo I just can't work out how if I want to move my strobe arm that it won't affect the position of the focus light. It would seem that if I loosen the strobe arm to move it the focus light arm will drop & then have to be readjusted. I can say that if even if that's the case it still looks better than what I am currently doing.
PS. How have you found the flotation works around the port? I have the same flotation on all 4 of my strobe arms and find they hit each other restricting my strobe arm placement when shooting macro.
Once again many thanks to jimswims,diverdave & Vondo no doubt we all have friends who just don't resonate with our desire to drag a camera around UW
