I found it easier to have my Magicband on my right wrist. Seemed like, since I am right-handed, I was able to make better contact with the Mickey Head that way. But what I mostly did during the trip was take off the Magicband and keep it on the
ECV handlebar. When I needed to use it, I removed it from the handlebar and just held it in my fingers. That worked best for successful contact on the first try.
