Buddy has it on his bike ans swears by. We are currently tryign to figure out how to adapt to snowboarding on the mountains for communication while still listening to music. Can apply to being at the track with the 5 mile range one or the cheaper 2 mile one for around $240. Nothing to push to talk. Just start talking and it relays it automatically. All you need and fits the budget and long *** range. You would have to be on the nurburgring to loose coms.
