You can see from the photo above that the Yongnuo RF-603 transceiver unit has a much lower profile than PT-04 Wireless Flash Receiver.
As mentioned earlier in my review, the RF-603 despite having an upgraded metal foot lacks a locking lever to secure it in place when attached to a flash stand / light stand. This is a must have to some people, but for me, it’s not that of a big issue.
Two places where Yongnuo lacks in ergonomics design, here’s one, in the placement of the channel dip switch and the On/Off switch. The channel dip switch is hidden inside the battery compartment making it hard to reach specially when you need to make quick last minute changes.
Above you can see the RF-603 and PT-04 with flash attached. Here’s the second place where the RF-603 lacks in ergonomics, once a flash is attached to the RF-603, there’s no way to reach the On/Off switch. I like how the On/Off switch of the PT-04 is positioned, even if there’s an attached flash, it is still reachable.

So which one will you get? It really depends, they bought work, the RF-603 offers more distance(100m), uses 2 regular AAA batteries, it’s a transceiver type device, each unit can act as a transmitter and / or a receiver, it’s also a wireless remote shutter release. On the other hand, the PT-04 has been here quite a while, works for most application, doesn’t have the ergonomics design flaw of the RF-603 that I have pointed out. I have both, currently I have 2 PT-04 transmitter and 4 receivers and a pair of RF-603 and 1 more pair on the way. I can use them together side by side thanks to the RF-603’s transceiver design, all I need is to attached my PT-04 transmitter on top of the RF-603 hot shoe and it will trigger my PT-04 receivers the same time the rf-603 triggers other rf-603’s. Let me just mention that after using the PT-04’s for almost a year, I’ve seen it misfire a lot of times, and I have to retake the photos because of luck of light. I find the RF-603’s pretty accurate especially in long distance application. But again, I have not tested this. In the end it’s a decision you have to make. If you can get by some of the mentioned weaknesses of both devices then one of them maybe right for your application.
