DIDSON High Definition Imaging Sonar and High Resolution Imaging Sonar

This film features high flow in turbid water.

DIDSON to be featured on The History Channel’s MonsterQuest!
AIRDATE: July 9, 2008. Check for more information.
The History Channel’s television series, MonsterQuest, used a DIDSON to search for giant snakes in Venezuela. As part of the upcoming episode, Ed Belcher discusses how sonars work and demonstrates a DIDSON imaging in turbid water.

DIDSONTM sets a new standard for high-definition sonar imaging. This ACOUSTIC CAMERA gives near video quality images for inspection and identification of objects underwater. It is a surrogate for optical systems in turbid water. The standard DIDSON operates at two frequencies (1.8 MHz and 1.1 MHz) and provides images of objects from 1 meter to over 30 meters in range. DIDSON LR operates at 0.70 MHz and 1.2 MHz and can image objects out to 80 meters. DIDSON is small and requires only 30 watts of power. Our current models can operate at depths from 100 m to 3000 m.
