With 128 beams operating at 3 MHz, the ARIS Explorer 3000 collects more data than any other imaging sonar in its class. Users get unmatched image clarity, even in the most turbid waters. For longer-range applications, Explorer 1800 (1.8 and 1.1 MHz dual frequency) and 1200 (1.2 and 0.7 MHz) models are available as well. The entire ARIS line is built to deliver in the most challenging situations. The small size and efficient power use makes the ARIS Explorer ideal for ROV/AUV integration. The ARIS Explorer models work in zero visibility and operates in waters from the artic to the equator. The ARIS Explorer sonars are manufactured by Sound Metrics Corporation, innovative leaders in underwater imaging equipment.
