JW FISHERS Scan - 650 Scanning Sonar Search System uig so their resistivity value isJW FISHERS Scan 650 Scanning Sonar Metal Detector Scanning sonar is an ideal tool for underwater search because it produces a picture of the underwater environment regardless of the water visibility. It does this by sending out a sound wave that reflects off objects on the bottom or in the water column. The reflected wave returns to the sonar head where it is received and sent to the surface for display. The reflected sonar image is displayed on a
