The Escort makes a great motorcycle detector because it has a built in ear phone jack. Get a set of ear buds that also double as hearing protectors and will stay in while putting the helmet on. I use the Etymotic 6i.I have an Escort 8500 in my car and it is great. Maybe i can go that route.
Do you have any type of alert in your helmet or do you have to constantly look down at the unit?
