thanks for the input, I appreciate it!
don't really care about crystal clear sound. just need to be able to relay that she can make it up an obstacle, to turn when shes not in my mirror, and the big question, is your foot hurting and do we need to go back to camp?
as long as we can communicate is the biggest hurdle.
what kind of range in between you and the other rider does it have? need to be able to see them? work around a corner?
