ABSTRACT:
An under ice crawler lowerable into a body of water through a hole in a layer of ice overtop is operable to extend a flexible line within the body of water between two points spaced along the ice. The crawler features a floating body having sliding surfaces defined at an upper limit thereof, a motor carried on the floating body to selectively drive a propeller, a connector carried on the floating body to facilitate the connection of the line thereto and a starting device carried on the floating body and actuable from thereabove. A termination device is carried on the floating body at a position distinct from that of the starting device to provide easy access. The starter device is actuable by lowering a starting-signal generator through the hole in the ice into proximity with a starting-signal sensor carried on the float body without requiring physical contact with the receiver.
