Transducer required with a fishfinder

General

Question

​Do I need a transducer with my fishfinder?

Solution

​Yes, a transducer is a required element that sends the signal down through the water and receives it back again.  It is required for your fishfinder to function. Most fishfinders are priced without a transducer as a standard item, thus allowing you to choose the transducer that best fits your needs.
