ABSTRACT:
A channel marker includes signals which are unique so that the identity of a marker is readily apparent even against background lighting. The signals may include lights, prisms, lenses, luminescent strips and reflectors. The number and disposition of the signals further identify a marker. Photo-voltaic means can recharge batteries.
