Depth matters verse how detailed one wants to see.
83 kHz which is typically a 60 degree wide cone equals the depth in diameter. 200 kHz is typically a 20 degree wide cone which equals 1/3rd of the depth in diameter. (Laymans terms and not the complicated math version.)
In 100 feet of water:
83Khz gives one a 100ft wide "cone" at the very bottom.
200Khz gives one a 33ft wide "cone" at the very bottom.
