I am using this to digitally scan books, so the "reach" I need is only 4 or 5 feet. I use one transmitter and two receivers (so I had to buy two products - couldn't find just a receiver). I set transmitter and the two receiver to channel 01, and when I push the transmitter button, both receivers cause the two digital Nikon SLR's to fire. That's all I need, and it works reliably.
