Its makers say the Volcano Digit is accurate, bringing that herb to ± 1.5°C of the perfect vaporization temperature. No more confusing switches and dials, the new and improved Volcano shows its progress to you in big bright LEDs, so you’ll be able to read no matter how toasted you are. Thanks again to the clever engeneering and application of the LED lighting system. Even though this Volcano Digit costs $669, we like the idea of reducing the most harmful aspect of pot smoking: It’s a gateway drug … to massive fast food consumption.
