Do you think the PE-2 was a bad purchase? Also, what about feeding Live? Did i scar him for life? LoL..
Personally I'm not a big fan of the cheaper temp guns. I don't think the PE-2 was a bad purchase, but you have to keep its limitations in mind when using it.

Try measuring the temperature of the top of the substrate over the hot spot with it. This is probably the best way to use a temp gun in a tub. They only measure surface temperatures, and have difficulty reading anything reflective.
