No, the one in the snow won't float, but was advertised to manage up to 20" of water safely. The first vid is a generation 2 marsh model, the tub and float ring are one unit. Seems as though the gen 1 models with the detachable ring had a nasty habit of the float ring floating off in deep water.

That's why I will be glassing the ring and tub together.
