Last night I took one of those plastic easter eggs that snaps together and filled it with bb's from my sons bb guns. Had to cut a little notch in the side for the wire and put the end of the indoor/outdoor temp probe in the center of the bb's. Then I taped the outside with electrical tape so it can't accidentally open and placed it in the turner. Took almost 2 hours for it to come up to temp and now the internal temp of my "probe egg" holds within .8 degrees. It ranges from 99.5 to 100.3. And it was free!
