MINI 48/78
High-speed mid-range communication and positioning for shallow-water operations
High-speed mid-range communication and positioning for shallow-water operations
MINI 48/78
The MINI 48/78 modem delivers full-duplex underwater communication and simultaneous positioning with our field-proven S2C acoustic technology. It supports fast data links up to 31.2 kbit/s over 1000 m, ensuring reliable performance in shallow and noisy environments.
MINI 48/78
With its horizontally omnidirectional, donut-shaped beam pattern, the 48/78 is optimal for fast data transfers in shallow waters and between devices operating at similar depths.

Naming and compatibility notice
Before mid-2025, this model was offered as S2C M 48/78. Our product naming has been streamlined for consistency - the MINI 48/78 modems are acoustically compatible with all existing S2C 48/78 devices.
Acoustic Performance Factors
Please note, that listed bitrate and operating range values refer to performance under optimal acoustic conditions and may vary with the environment. These figures indicate the upper limits of modem performance rather than guaranteed real-world results. Acoustic performance - including achievable range and data rate - depends on both environmental factors and the installation setup. It can be influenced by multipath propagation, variations in the sound velocity profile, ambient noise levels, and interference from vessel systems or nearby machinery. Optimal conditions typically include a calm sea state, low background noise, a uniform sound velocity profile, line-of-sight geometry, minimal multipath, and proper transducer placement.
