Well as good as the Elinchrom Ranger RX is, the sync port is a proprietry sync port. Sure the unit came with a 5m pc-sync to elinchrom cable but I have wireless flash triggers (YongNuo RF-602) and being corded to the power pack is not ideal or fun. I cut the last few inches off the included sync cable and put on a 1/4″ (6.35mm) socket to take my triggers. I do have the Skyport RX’s but the Skyport and charger share the same port so if it’s on charge (shooting indoors) then I’d need to use the sync port which is where this cable comes in handy. Paying $70 odd for this same cable from Elinchrom didn’t appeal much to me, especially when the 1/4″ socket was $1.65 from Jaycar.
