yeah every snake keeper has their preferences and husbandry techniques. i myself hold firm to the need for a digital thermometer/hygrometer. even if you put the analog thermometer on the cage floor or substrate it still isnt going to be as accurate as a digital one. my analog gauges were 15 degrees off on temperature and 10% off on humidity. i was heating the tank floor up too hot and trying to acheive too high of a humidity level because i thought it was really low. i spent the extra money on the nicer analog gauges too because i thought they would be better. that's why i'm all in favor of the accurite.
