I have been getting some variable temperature readings in my mash tun with a type K thermocouple probe.

I mash in, stir the holy hell out of the the mash and then take a reading
and often times I get about about 10 degrees of variability with my thermocouple. Never do I get that sort of variability in say, my hot liquor tank.
My mash tun is a big 60 qt Igloo ultratherme cooler, so it shouldn't be leaking that much heat.
Anyone know if there is some sort of interaction going on with the probe? Could I really still have heat gradation that big even after a good stirring?
If I put in a dial thermometer, of course I get a less jumpy reading.. but I'm not sure if that's because it's so slow...
I am thinking somehow, there is some sort of interference going on with the type K probe..
Ideas? This has been frustrating, because it seems I cannot trust my K probe to give me a good read, and sometimes I get pretty nervous that I might have overshot my temp and decreased my fermentability.
Maybe I just need to dump the thermocouple and get something like this:
