Yeah, I think it's the on/off types. It's the ZooMed RepitiTemp RT-600. They're the "cheapest" I'd go with. Is an upgrade to something like a Herpstat 1 Basic worth it?

I've also seen different temp positions such as hanging it secured w/ some hot glue. The probes are pretty fat plastic ones where I'd need to drill a new hole if I wanted to run it through the wall. I wouldn't be able to pass it through the LED or RHP hole already drilled.

I've been running it for about 16 hours now.
Temps in F.

95-97 on top of rock hide
88-92 on substrate around hide and in hide
85-80 to about the middle
Then it's 75 on the opposite side near the wall I understand that the 75 if LOWEST you should really have. But then again my BP only goes out at night to explore and usually ends up coming back to her warm hide always. On my old/current setup I was able to get 90-92F belly heat 24/7 with a UTH.
83F in the air ambient.

Is this fine or should I play with a different temp probe position? It's currently set to 85F
