bay in british colombia. i'm with phil nuytten. he's a internationally known as a deep water dive expert. you actually develop vehicles like this so people can go deep in the water, places they never have before. and something i have been learning from you as we have been down here is how difficult, even the simplest move seems to be. >> yes. it tends to be quite a chore. no question about it. the biggest attribute you need for this kind of work is patience. >> show us. we have a mock up of a black box. of what a black box would look like down here. it is already in the claw n the device on the outside of the vehicle here. it takes more than ten minutes under the best circumstances for that claw to grab the handle. now, watch what happens when we try to put it in to the basket that we'd need to take it back up to the surface. go ahead. this isn't something you think would be difficult, but you have to move by inches here.
