Your company has several surplus navy work vessels, essentially old tuna/salmon boats, which work out of both the east and west coasts. Each has with it a small Bathescope and Hydrolabs which can carry and help divers and go beneath the water's surface several hundred feet to view wreckage of older ships in order to gauge their worth and possible treasure. An example designed by a Standford group, called the "Otter", is seen below. You started this business as an outgrowth of a dive shop you managed some years back. The last few years you have found three ships from the time of the American revolution which were sunk and carried items of worth to museums and collectors.
