ABSTRACT:
A portable marker and retriever assembly is designed to be attached to a snowmobile or some similar vehicle. In one application, the assembly releases a tethered float in that situation when the snow mobile breaks through ice and sinks below the surface of a body of water. In another situation, the tether can be attached from one snowmobile to another to facilitate a towing operation.
