The Mardis-Dranginis sonar reading was captured on July 4th, 2017, near the southernmost mouth of New York's Ausable River.
The reading was picked up in the evening at roughly the same location that the Bodette film was allegedly shot. The reading shows a "drumstick" shaped object that allegedly swam underneath the men's boat. The reading is only recorded in the form of cell phone photographs, due to a lack of SD card in the equipment at the time.
The reading itself, according to Scott Mardis and the late William Dranginis, swam about fifty feet beneath their boat. The sonar indicates, too, that the object was roughly twelve feet in length.
The object was not picked up after two minutes and remains unidentified.
The Champ Search sonar reading was captured on August 5th, 2019 at a depth of roughly one-hundred and sixty-five feet.
The sonar reading details two objects located underneath the sediment floor of Lake Champlain. The objects are narrow, appear to curve in various places, and are roughly seventy-two feet in length. It is unclear as to exactly when the objects entered the sediment, as no clear entry point can be observed.
A follow-up sonar reading days after the initial contact shows these objects had since moved away and were not relocated. The time gap between these two readings leaves whether or not they moved due to underwater forces, or of their own volition, unknown. Despite attempts to analyze them, the quality of sonar leaves their identity also unknown.
The Tokyo Broadcasting sonar readings were captured by a Japanese expedition team in 1993 near Potash Bay, Vermont. The reading shows a large object that comes up and down in the water several times. At several points the object "dives" close and sometimes even into the sediment of the lake. The identity of the object is still unknown.
It should be regarded that, although the article shown to the left references "Champtany", which is a term that refers to the tanystropheus theory, the LCZI does not necessarily reflect any views posited by listed articles.
