Temperature guns (infrared temp devices) vary in precision and accuracy, although they have all gotten better in the last 5 years. The best ones have a setting that allows you to compensate for the material being measured. For example, when you read the temperature of a metal using this device, the reading may be slightly different than measuring the temp of wood at exactly the same temperature. That is because these two materials radiate heat differently.
In general, for snakes and wood and plastic, any general temp gun is fine, but you will be happier if you get one with a laser sight so you know where you are reading the temp.
