I used to use the FRS (family radio service) stuff a lot. The motorola, uniden, some others have ear pieces that also have microphones. They can be set to voice activated but wind or other ambient noise might key them up when not intended. I used to clip a receiver to each kid's handlebars. When they got too far ahead (I was pulling a burley) I would key up and shout, "tighten up." They would also call back ocasionally and ask for directions.
