EdgeTech is a leading manufacturer of underwater technology solutions. The company is known worldwide for its high quality products which include: side scan sonars, sub-bottom profilers, bathymetry systems, AUV and ROV-based sonar systems, combined and customized solutions. In addition to the full line of underwater survey products, EdgeTech provides reliable USBL systems, transponder beacons, deep sea acoustic releases, shallow water and long life acoustic releases, MRUs and customized underwater acoustic command and control systems.

The company traces its history back to 1965 when it started out as a division of EG&G Marine Instruments. In 1995, EdgeTech became a private company and selected its name in part to honor the late Dr. Edgerton, an MIT professor, marine instrumentation pioneer and a founder of EG&G. In 2012 ORE Offshore, a leading provider of acoustic releases, transponders and USBL systems, adopted the EdgeTech name after over ten years operating as an affiliate organization within the company.

The company has a comprehensive suite of in-house testing facilities including test pools, acoustic test tanks, pressure test chambers and two company research vessels used for testing and sea trials. These facilities allow the companies to fully test and calibrate every system to ensure the delivery of the most reliable and highest quality products and systems.

From ship hull inspection and underwater mapping to nautical charting and oil and gas surveys, for more than 40 years EdgeTech has been the industry leader in providing underwater imaging systems to commercial, government, research and military institutions worldwide.

CAT Coastal Acoustic Transponder

The Coastal Acoustic Transponder (CAT) is ideal for deployments in coastal environments. The acoustic command structure is the same as that used in all of our underwater acoustic releases and transponders and is unsurpassed in multi-path environments.
The CAT has been designed for use as an underwater instrument location and positioning aid. They have applications as part of the recovery system on oceanographic moorings and platforms. The precision, high output power and commandable transponder feature make these instruments ideal for use with positioning systems in difficult acoustic environments.

The CAT utilizes EdgeTech’s field proven Binary Acoustic Command System (BACS) code structure. The BACS coding structure provides 12,000 possible secure command codes. Each transponder is factory programmed with its own unique command set which includes transponder ENABLE, DISABLE. Whenever the instrument receives a command it responds with a status reply message which indicates the orientation of the instrument (tilted or not tilted).

The transponder function can be turned on or off with the ENABLE and DISABLE commands. When disabled the transponder will not reply when interrogated. This ensures that the unit will not interfere with nearby instruments and that no battery energy is wasted replying to interrogate signals meant for other systems.

Key features:
 - Easy maintenance
 - Small lightweight package
 - Full transponder capability
 - Two year life on alkaline batteries
