Having lived in Honduras from 1979 to 1982 and spent several years later on in the country, I can attest to the slave-like conditions that the lobster divers lived along the Mosquito Coastal area. It hasn't changed much since those days. No equipment to speak of, doing ten to twenty dives a day, most of the divers were crippled up by the time the got to their thirties. They had no, and have no choice in the matter. It's dive for the rich guy who owns the boat or their children starve or die from malnutrition. If you boycott their products the same thing will happen. It's a sad situation. As far as a depth guage, SPG or pressure guage is concerned, that's a waste of time. These divers already damn well know the depth and the pressure.
