Define Fathometer with the odolite - Sounding/Sensing Devices?
The horizontal scale problem in use of Fathometer can be solved by using equipment, which combines a Fathometer with a total station theodolite. The theodolite is set up on shore, it tracks and records the coordinates of the transducer, and automatically records depths at specified increments using a microprocessor. The data can be plotted on a topographic map.
