Why Marine Sonic Technology?

Marine Sonic Technology (MST) is a leading provider of ultra-high-resolution side-scan sonar systems for any application. Our Sea Scan® product line is one of the most advanced in the world for underwater imaging.

Our systems are suitable for applications in a variety of fields, such as:

Based in Yorktown, Virginia, USA, Marine Sonic Technology has been in business since the early 1990s, and prides itself on having the best relationships with customers of any underwater imaging company.

Ultra high-resolution side-scan sonar

Offering high-definition digital and adaptive compressed high-intensity radar pulse (CHIRP) models, our systems can be configured for standalone, towed and deep-tow systems, along with autonomous underwater vehicle (AUV) and remotely-operated underwater vehicle (ROV) applications.

In addition to various transducer packages with frequencies starting from 150kHz, MST has the highest resolution transducer currently on the market at 1,800kHz.

Our systems are shipped with standard dual frequencies and typical setups of 300kHz to 900kHz, 600kHz to 1,200kHz and 900kHz to 1,800kHz.

Side-scan sonar systems and adaptive CHIRP-towed systems

The Sea Scan® HDS was our first, fully digital, entry-level towed system and was one of the most powerful, yet easy to use, systems in the industry.

  • It is suitable for the harsh environments of commercial work.
  • Although we no longer manufacture the HDS, many remain in the field and are still used in maritime missions.

Our more advanced adaptive CHIRP-towed system is the Sea Scan® ARC Explorer.

  • With more flexibility than any other system, the ARC Explorer allows clients to change between standard dual frequencies, as offered in the HDS, as well as change out the entire transducer in less than 5 min on the boat deck.
  • It is fully ruggedized and milled from a single piece of billet aluminum with expansion ports for later upgrades.

The Sea Scan® ARC Scout Mk II is our adaptive CHIRP embedded system for the AUV and ROV markets.  The ARC Scout Mk II is the smallest, dual-simultaneous transmission, embedded side-scan on the market.  Its compact design allows it to fit in almost any AUV or ROV currently in use.

  • Its all-inclusive, ultra-compact package measures 12.7cm x 5.9cm x 2.6cm, in single frequency (with two packages required for dual frequency).
  • Virtually ‘plug-and-play’ installation and minimal power usage make it the perfect choice for AUVs and ROVs that don’t have room or power to spare.
  • It brings NATO caliber imaging in class-leading space, weight, & power (SWAP).

Sea Scan® Ranger is the most recent addition to our imaging sonar line up.  This high-performance Synthetic Aperture Sonar (SAS) is designed to fit in small to medium-sized AUVs.  Its class-leading technology is offered at an untouchable price point.  Ranger delivers 300 meters of swath coverage and an amazing 3 cm of resolution while consuming on only 30 watts of power.

  • Ranger’s electronics require minimal dryspace (about the area of a modern smartphone) with SWAP-leading packaging of 12.7cm x 5.9cm x 2.6cm and a mass of 195 grams.
  • Ranger’s transducers are customized for a perfect fit on any AUV with a small envelope of 94.5 cm X 7 cm X 4.5 cm
  • Ranger delivers fast, consistent coverage, top-of-the-line resolution, and easy integration.


Customisable data collection software packages

The Sea Scan® Survey by MSTL is the most intuitive and powerful software package available. With its extremely powerful tools and ease of use, it handles almost any task without the need for extensive training.

An operator can be up and running within a few hours without the fear of pushing the wrong button. Sea Scan® Survey collects and saves raw data, allowing for manipulation without destruction.

The package can be integrated with most third party mosaic software packages, such as SonarWiz, and is fully adaptable, giving end users the ability to design their own software to fit a specific and unique need to their application by offering a software development kit.

We are constantly improving our software, which is driven by our end users. Upgrades are available for free for the life of the system and can be downloaded and installed from our website.
