Forward-looking Sonar Upgrade

FarSounder will be launching a software upgrade for its FarSounder-500 and FarSounder-1000 forward-looking navigation sonars. The upgrade will increase the intuitive nature of the information and enhance users' understanding of the obstacles and sea bed ahead of their ship. The full release will be announced at SMM Hamburg and the Monaco Yacht Show later this year. At FarSounder’s recent customer demonstrations and technical training class, participants were introduced to a few of the upcoming new capabilities. A sampling of these features included Ping-to-Ping Sea Floor Stabilisation, Improved Sea Floor Imaging and Sea Floor Chart Overlay. FarSounder’s guests saw a demonstration... (read more)

SeaKing Hammerhead DST Sonar

Tritech International has launched its new addition to the SeaKing family of imaging scanning sonar products - the Hammerhead scanning sonar. The unit can create higher resolution imagery than comparative mechanical scanning imaging sonars by utilising a large transducer aperture, very fine mechanical step size and proven Digital Sonar Technology. As standard the SeaKing Hammerhead sonar has two frequencies of operation: a high chirped 935 kHz frequency to enable high resolution imagery, and a second chirped frequency, 675 kHz, to allow for long range capability. The wide transducer allows for a very narrow horizontal beam to be created on both... (read more)

Side-scan Sonar Demonstration

GeoAcoustics has launched Sonar 2094 Digital. A series of seminars and demonstrations were held by Simrad Spain, the local Kongsberg office, in November and December of the past year for their naval, scientific and industry customers. The capabilities of this technology for environmental mapping, engineering and archaeology surveys as well as object detection and classification were shown in various places along the Mediterranean coast.   Sonar 2094 Digital is the successor of the Dual Frequency Side-scan sonar, which was first launched in 1996 and developed into an industry standard, with over 1,000 units sold worldwide. Sonar 2094 Digital combines the... (read more)

3D Sonar Technology

The journey from oil and gas to homeland security and back again
Since its introduction many years ago, survey sonar has evolved steadily, but is still a difficult and non-intuitive survey tool, requiring large amounts of processing to arrive at the most basic end product. Initially, anyone wanting to survey or inspect the underwater environment was limited to single beam echo-sounders, in simple terms one-dimensional sonar, yielding very little quantifiable data. These in turn were developed into mechanically scanned sonars, and subsequently into today’s high performance multi-beam and forward looking sonars which are the back-bone of the survey industry. Even the very best commercially available multi-beam sonar delivers only 2 dimensional data... (read more)

Side-scan Sonar Seminar

A Side-scan Sonar Operations and Maintenance Training Seminar is to take place from 17th to 19th May, 2011. The seminar will be conducted at L-3 Klein's Facility in Salem, NH, USA. The training will include two days of classroom instruction and 1 day of on the water training; lunch will be provided daily. This seminar is geared to the operator, as well as to the manager, who wants a better understanding of Side Scan Sonar techniques. The course is open to any user of side-scan sonar regardless of brand, experience, or occupation. The instructor for the course will be Garry... (read more)

Sonar Interface Unit

The Octopus 160 sonar interface unit's design and is compact, rugged and weather-proof. Compatible with EdgeTech's work-horse 272TD dual-frequency side-scan sonar, it is simple to operate and is suitable for small boat use in many types of underwater survey. Housed in a rugged custom Pelicase, the 160 is highly portable and it can be operated with the lid closed allowing uninterrupted operation in harsh environments.   Another popular feature is the new user interface for all controls and once configured for a specific towfish, this needs no further adjustment. With direct connection to standard EdgeTech 272TD tow cables and full... (read more)

Versatile Side-scan Sonar

JW Fishers developed a side-scan towfish with adjustable transducers. The angle of the transducers can be changed by rotating the tail section of the towfish. This allows the sonar to scan the hull of a ship for attached contraband compartments and inspect the face of a dam, bridge, or oil platform for explosive devices. Already several departments have purchased these side scans with the new adjustable transducers including the Escambia Sheriff’s Office in Pensacola (FL, USA) and the Washington County Sheriff’s Office in Stillwater (MI, USA).  Jim Anderson of Washington County’s Water Recovery Unit says to be impressed with the...

‘Killer’ AUV Sonar System

In January 2001, C&C Technologies (C&C), a company based in Lafayette (Louisiana, USA), introduced the first commercially successful autonomous underwater vehicle (AUV) to the offshore industry. The AUV’s survey sensor suite, which included an EdgeTech side-scan sonar and sub-bottom profiler, performed well in the Gulf of Mexico and Brazilian offshore environments. However, West Africa proved more challenging – particularly for the sub-bottom profiler. C&C soon began searching for alternative technologies to provide better sub-bottom profiler penetration and higher resolution side-scan sonar imaging.Jim Chance, C&C Technologies (USA) Art Kleiner, EdgeTech (USA)<P> Narrator: Fast forward to the early autumn of 2004… C&C...
