Rr your a smart guy. Can you explain the temperature thing in the delay setting area? I do love the delay setting. Even though I have never needed a delay it's nice to see the feedback in terms of milliseconds, meters, and feet. It's nice to that you can manually enter the distance and then the rest is set for you.
If the temp thing deals with delay I am very confused. I understand that certain temps can affect the speed of sound but humidity levels play a big part in that. I have two homes now. One in the freezing north, and one in south Florida. Humidity levels, even at the same temp, are very different.
