After about 1 1/2 years my probes started reading via the ice water test +5 in port 1 and +7 in port 2. For consistency I always place my probes in the same ports although not always using both of them.
I found these waterproof probes on Amazon

After I received them I checked them again using Ice Water. They were outside of the accuracy range for the ET-733. Thinking that I may have a problem with the transmitter I called Maverick and explained what I was experiencing and the first thing that the Customer Rep. told me was that the Ice Water test was not the most accurate method for checking the probes. Maverick uses boiling water preferably adjusted using Barometric pressure and or Altitude. I found the following calculator on line.

Using both pressure and altitude I ran the tests and both of the new probes read 112 degrees. I then used this method to check the old probes and they both were with in the accuracy range for the 733. (port 1 was 111 and port 2 was 113) close enough for what we do. As the saying goes....your never too old to learn some thing new.
This may be old news for some but I thought I'd share it.
As an aside Maverick will sell just a transmitter.
