yes I know they are not exactly very accurate I put it against the heat mat above the glass to get an idea about the heat since if I put it against the glass it shows the degree against the glass and not the area surrounding it, but again thank you that was extremely helpful!
I ordered a temp gun from amazon so it should get here soon, and my snake is 5 months old, the enclosure is bigger than him by a few inches but I will check his exact size in a while as well as post more pictures of the enclosure.
he has a heat lamp that I turn on in the mornings and close at night.
