BTech has production capabilities and currently manufactures a line of broadband underwater acoustic modem transducers including single crystal transducers for unmanned underwater vehicles, gateway buoys and fixed platforms. We have produced single high sensitivity hydrophones, pressure gradient sensors and accelerometers.

BTech provides a large variety of services including transducer testing and calibration, transducer and system design consulting,  measurement system development, processing, performance modeling, and software development. We develop and produce underwater acoustic modem transducers and indepth technical reports about the design and operation of sonar transducers and arrays. We are currently developing a new line of measurement systems and software for acoustic and non-acoustic sensors as well as the development of low frequency (<1kHz) projectors. We also support instrumentation and measurements of marine mammal studies.
