Uth not sticking properly

[tttaylorrr]

So looking at the ultra therm uth they range between 65-95 degrees so you don't need a tempstat? And will I have the same issue of a bubble where the probe goes?

they do not get as hot as other UTHs and they say you don't need a thermostat, but i still use thermostats with mine. yes there is still the bump issue with the probe, but i've never had issues with it. i've aluminum taped the UTH tight enough to the enclosures and placed the probe off center from where the snake will be spending its time so it's not really an issue (3/4 of my enclosures have the bump; T8 has a probe channel for it to sit in).
there's ways to remedy the bump issue if you're still concerned, however. is your enclosure raised off of whatever it's on? you could get two blocks of styrofoam for the enclosure to sit on and cut a channel into the one on the hot side for the probe to rest in. you could also tape the probe wire to the underside of the UTH (facing the floor), but you can't tape the probe head itself.
