At one end of the Pro-Series Tools Temp-Driver is an accurate infra-red temperature sensor, and at the other is a flat blade screwdriver for tuning all three needles of your nitro or gas engine. Use the Pro-Series Tools Temp-Driver to check the temperature of your Nitro engine and tune it properly. Use the cone protector to accurately aim your sensor at the plug to obtain the correct temperature reading, then spin the tool in the palm of your hand and tune your engine to perfection.
