Hey I just got a boa masters rack at the white plains show and am having issues with heating. They gave me back heat an I hadn't noticed so I've been working with it. I got a ve-100 with the probe in the middle of the length of heat tape with the stat set at 90 all of my Acu-Rites were reading 100-113!!! So I bought some 3" belly heat now. Plugged it in, probe in the middle of the length and now I have temps of 95-105! Help! What's wrong?!
