Just something I thought I would share that I have not seen commented on before. I have been using the new 5.3 coil the last couple of days and I when I tried to use the sensitivity probe it simply was not there. I thought it might have had something to do with the coil since I had never had a problem before. I finally figured out that when you push the view button with sensitivity selected from the live control bar, the rx gain slider must be highlighted for the sensitivity probe to appear. If am or disc sensitivity is highlighted the probe will not show. A year and a half and I am still learning.
