An economical, basic infrared remote control system with great performance.
Wein PST-500-1 Pro-Sync 1-Channel Transmitter
This infrared transmitter can be mounted on, and fired by any standard camera hot shoe (or connected to a PC terminal for off-shoe use). Just slide the compact transmitter onto your camera; no cords, no antenna, nothing to clip to your belt. A pair of "AA" batteries in the transmitter powers up to 5,000 shots, with recycle times averaging less than a second - faster than most any flash.
Each time you shoot, the transmitter fires, and an "explosion" of coded infrared light fills the room, bouncing off walls and around corners. You can't see the signal (neither can your film), but the Pro-Sync receiver does.
Wein PSR-500-1 Pro-Sync (Household)
Plugged into your remote flash, the Pro-Sync receiver is in a "standby" mode. Pro-Sync receivers can easily pick up the signal from behind backdrops, soft boxes, even around a roomful of wedding guests. Nothing else can trigger the receiver, not even a full-power flash fired inches away. They work indoors or out, with a maximum range of 600 feet (indoors).
The receiver draws power from the flash to which it is connected; there are no batteries to change on the receiver. This receiver is a Male Household (2 prong) type. Receivers are also available with phono plug sync connectors, so they connect directly, cordlessly, to most professional flash units or power packs. For additional versatility, each receiver also has a standard PC terminal.
