Sonar Imaging

Using the JW Fishers Side Scan Sonar-100K/600K, we are able to view large search areas quickly and produce high-resolution images of the river bottom up to 40 meters from the sonar head. This model has both low and high frequency transducers in one towfish. The towfish is rated for 500 feet depth and is equipped with 150 feet of cable. The data that is collected is then sent to a laptop computer where it can display a real time color image of the river or ocean bottom.
