The sealed no leaks construction of this hand powered Dry Vac has enormous vacuuming power. No need to leave gold just laying there at the dig anymore because you didn't bring all of the right tools. Here it is, a hand powered "Convoluted Cylinder Bellows" dry vac that holds up under the threat of abrasive wear and won't loose vacuum or any values 
being retrieved.
Without a rod and piston like a bicycle pumps has, the white handle can be pulled in just about any direction, stretching the bellows to create vacuum! This makes it easier to operate from many angles without having to adjust your position.
Since the bellows is a memory plastic, it re-coils back down to it's original shape if the handle is released!
