This is the only place showing a pic of the new probe. It's possible other places haven't updated their websites. Since BRS and Neptune are kind of one in the same, I can't imagine that they don't have it, unless they are still trying to clear out the old version.
Buy this probe if you are: - Replacing an old probe- Adding another tank to your system via a PM1 - Want to have more accurate readings on your PM2/PM3 modules by adding temperature compensation
