1st post and 1st Bp I’m getting her next week. I just put my tub together and it’s ready except I have a T-Rex UTH and foil taped the probe of a ESU 1000 to the T-rex and them taped the mat to the bottom of the tub,but now there is a area of space where the mat doesn’t touch the bottom of the tub. It’s like pooched up in the middle where the probe is. Is this ok and will I get a ture reading? I’ve been to alot of forums on BPs and have never seeen the bottom of a tub with the UTH on it already to go. If anybody knows of a pic please let me have it.
