Here is a great system for the price! This durable cousin to the popular electronic race system gets the job done for your CO2 racing. Both vehicles are fired simultaneously from the metal start gate with the “push” of a lever and features the same “car saving” brake gate as the electronic version. No timers or starting lights, but this system does indicate the winning lane with a red light on the brake gate. It is made of solid metal with enough weight to keep the fishing line guide tight, which keeps CO2 dragsters racing in a straight line.
