A couple people sent me PM's asking about how I place my Temperature Probe for my Helix's onto the heat tape, so hear is a pic. The piece of plastic I use is actually just a piece of plastic that I cut off of one of the lids for a CB-70, but I guess you could use the lid from whatever kind of tub you have. Then I place the probe on the plastic piece, and cover it with some folded up paper towel. Tape all of that together with 2" packing tape. Then I tape the whole assembly to the heat tape using 2" packing tape. My theory in doing this is that I get readings in the tub that are closer to the temperature displayed on my Helix, because the probe is measuring temperature through the same plastic that my tubs are made of. In theory it's like putting the probe in a tub without having to put the probe in the tub.
