I have Yongnuo RF 603NII N3 transceiver (2 pieces). I would like to know whether we can use it without connecting one piece to YN-565EX II Flash Unit i.e. one piece of transceiver will be in my camera hot-shoe, do I need to attach the other piece in the flash unit if the flash unit is YN 565EX II? Or I can use other transceiver as remote trigger in my hand?
I am asking this because both my transceiver and flash unit are Yongnuo
PS: I am yet to buy flash unit.
Thanks in Advance !!
