The default frequency is 200 kHz, which is best for use in shallow wa-

ter (about 300 feet or less). This frequency is the best choice for about 

80 percent of the fresh and salt water sport fishing applications. When 

you get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz 

frequency is the best choice. 
The 200 kHz transducer will give you better detail and definition, but 

less depth penetration. The 50 kHz transducer will give you greater 

depth penetration, but a little less detail and less definition. (Remember, 

all sonar units typically read deeper in fresh water than in salt water.) 
There is a common exception to these rules of thumb. Some fishermen 

on freshwater lakes (or the ocean) using downriggers like to see them 

on the sonar. In many of those cases, you'll see a 50 kHz transducer 

frequency in use because the wider cone angle lets them watch the bait.
