When you use any of the Pro Series equipment with the original Modules or Receivers, you WILL get an improvement in your latency. The original system's total latency was 5.6milliseconds. When you upgrade to the Pro Series Module and Receiver, the total latency is cut nearly in half to only 3ms. If you run an Original Module with a Pro Series Reciever or a Pro Series Module with an original receier, you will get half the gain in latency for a total of 4.3ms.
