The FSI ACM-PLUS is the next generation of single-point Acoustic Current Meter (ACM) technology, offering new features, functionality, and benefits that will enhance your ability to measure current speed and direction. Key advantages are the ability to make accurate measurements in very clear and/or very shallow water, as well as right at the surface and sea-floor boundary areas. Data can be acquired in real-time or captured and logged in internal memory. FSI offers shallow (200m) and deep (7,000m) versions as well as options to add an integrated CTD and one or two external sensors.

FSI also offers instruments to measure waves, tides, and other environmental parameters such as structural vibration and stress.


The HMS-620 Bubble Gun (tm) low-frequency, ultra-portable seismic system makes it possible to capture high-quality survey data from a small boat without the need for support equipment, deployment infrastructure, or heavy machinery. We even offer a 24 VDC battery power option so you can leave your generator at home.

FSI also offers sidescan sonar systems, hull mount arrays, and other specialized transducer systems.


FSI’s service areas include custom design, development, integration, and production of marine systems and acoustic transducers; and manufacturing services such as prototyping, product assembly, encapsulation (potting), calibration, and pressure testing. FSI excels in rapid prototype fabrication of acoustic transducers and subsystems.
