this is exactly why. i own a blood python and they are a bit pickier with the temps than an avg bp. I want to make sure my cold side and heat side arnt to extreme. And the current one i own only works ok if its been sitting inside the tank for a bit, other wise if you have the top open (even for a sec) it will not read the correct temp or humidity. I plan on cont. to use my original one to monitor humidity but the temp gun will be wayyyy better to see the different temp ranges in the cage.
