Marty, Thanks so much for this website Photostrobe trigger!
WOW , I was using a Vivitar 2800 on my hot shoe and Nikon
costumer service said ok! This speedlite generates only 3.75V
against whatever the 3 photographers said, higher , of course!
anyway, I had a brief on flash topic during my course, but I
will go back in October.
I do not have the manual for the speedlite 300tl, do you know
where I can get it ( for free, please) thanks once
