I'm not sure what heat source you are using, but if it's an UTH you need it to be outside the cage like Craig mentioned, sandwiched between the UTH and bottom of the cage/tub.
Ok thanks. It is only a 10gal tank at the moment with UTH as it is a baby. i will move the probe to underneath the tank below the UTH and see how it reads than. Curious though would that not show a higher reading as it is below the UTH between tank and surface trapping the heat?
