Blowers

Can someone explain to me how the blowers work I have been seeing on the boats? Totally Rookie

aquacop911,
The blowers on the back of treasure boats pivot down and locks down over the props. With the props turning, this propels fresh water down on the sand floor and flushes the loose sand leaving "blow holes" and, hopefully, items left behind. Usually works best in 50' or less. We have extentions we can add for deeper depths.
