It eliminates the water surface glare and allows viewing as far as water clarity and light permit. The underwater viewer can be used for observing reefs, checking boat moorings, secchi disks and other survey work. It is also used as educational tool to watch plants, creatures and habitats underneath the surface of rivers, lakes and seas.A more advanced version, an underwater telescope was patented by Sarah Mather in 1845 and permitted sea-going vessels to survey the depths of the ocean. It used a camphine lamp in a glass globe that was sunk in the water. The device allowed to examine the hull and other details from a person on the deck of a boat. In 1864 Sarah Mather added an improvement to her previous invention to detect Southern underwater warships."@en }
