Submertec has developed products which are in use on a number of passenger carrying submarines including the following:

The colour Spyball pan and tilt camera would be well suited for use as a periscope or masthead camera and could provide an economic alternative to multiple camera systems.

Care has been taken to ensure that they are easy to maintain and impervious to corrosion.

Four external cameras controlled from a panel mounted unit allowing easy selection of any camera or VCR input to any of four separate display groups.

Stainless Steel probes installed in external seawater hard ballast tanks allow the contents to be displayed for compensation of changing passenger weight between dives.

Bar graphs for each tank show ballast distribution and a digital readout displays contents in litres.
