According to their website the original course is 80 feet above ground. The extreme course is 200 feet above ground. The monster is 300 ft above. Depending on the course you choose the lines are different lengths. I did the extreme and yes, the lines were about 20-30 seconds but we did five of them. Totally worth the cost.
About 20-30 feet up and the main one lasts about 20 seconds.
