  • The transducer takes the charge of sending or receiving the sound waves.
  • It sends sound waves under water as a beam and as it strikes any object it reflect which send direct signal to the display.
  • For shallow water wide beam is preferable while for deep water narrow beam will work wonderfully.
  • As the sound waves penetrates to soft under water substance it appears as hard material where as hard objects tends to appear as soft materials. Experience is required to learn its usage.
