The "Sync Cord", your only link between camera and flash, is essential to your success. If it fails during a shoot, it can destroy the job along with your reputation! The sync cord is a vital piece of equipment, not to be taken for granted. Why risk connecting a high-end camera to a professional flash with an unreliable or inferior cord?Household (Gold Plated) fits Lumedyne, Norman, Braun and Dynalite, and most professional flashes with dual blade receptacle. Gold plated contacts gives better contact for all applications. Units with 3-prong plug can also use this plug. Examples of the 3-prong plug are Dynalite (3 flat blades), Sunpak and Quantum Radio 4i (2 flat blades with 1 round blade in center). Third prongs prevent plugging these cords into wall sockets!Long Tip PC (Gold Plated) is recommended for all 35MM cameras with PC fittings and a must for the newer Hasselblad lenses. Fits Hasselblad CF, T-Star and Bronica cameras. Not as tight as Paramount standard PC, the extended, tapered tip allows for easy insertion and removal. The PC Long Tip and PC Long Tip (Gold Plated) are identical except for the gold finish.
