YSI Profiler System USER Manual
There are three bottom depth options: 1) user-defined; 2) using a depth sounder sensor; and 3)
using a fixed reference sonde. The descriptions and the table below should help you choose the
appropriate setup for your application.
User defined applications are typically employed when the winch and electronics can be
mounted to a fixed structure. The water level should not change significantly in depth and
extreme bottom monitoring is not important.
Depth sounder applications are often used to track the bottom of a body of water and adjust the
program to get within a specified distance from the bottom.
Fixed reference sonde applications are used to track water level and adjust the program to a
specified distance from the bottom, but it is always used with fixed mount winch and electronics.
