An underwater monitor--but why?

You've got to wonder what DHS investigators think of stuff like this. After all, it's not as if there are an overwhelming number of practical consumer applications for an underwater monitor kit like this one, which we saw on Red Ferret.

Manufactured in China, the "full-set" kit apparently includes a 7-inch LCD, a five-hour battery and a diving camera with night-vision range of 9 to 15 feet. The equipment can all be conveniently stored in a metal carrying case that--we hope--would be subject to careful inspection near ports, bridges or any other appropriate locations.
