Leaders In Underwater Inspection , Survey & Rescue
Our new sonar technology uses live sonar imagery to find underwater sunken vehicles, vessels and many other lost assets. The sonar system allows constant monitoring of any underwater object from any angle and depth. This unique system provides high resolution sonar video with exceptional detail and accuracy for later viewing. The sonar is perfect for viewing fixed structures where the water quality and visibility is poor allowing for a comprehensive visual understanding of what is happening beneath the water surface. The sonar scans assets such as bridges and culverts, dock walls and pilings, piles and sheet pile walls, pontoons, aqueducts and viaducts. Deliverables are in the form of a video file and can be linked to GPS.
