Need pics of how you have your probe placement

[L.West]

For back heat, I place my probe on the middle shelf between the tub and flexwatt. I wanted the reading to be closer to the tub temp than the flexwatt. My thermostat is set to 100 and getting a 88-90 hot spot and 80-82 cool side. The actual flex is like 115 tho....

For belly heat, my probe is on the flexwatt as it isn't as hot as the back heat flexwatt.

So, what you are saying is to tape the probe to the shelf just behind the tub but directly in front of the heattape - but not touching it - is this correct.

The only problem I see is - I thought running the heattape at 115 wasn't recommended.
