Long-distance communication and positioning for deep-water operations
PRO 7/17 dir
The PRO 7/17 dir modem delivers full-duplex underwater communication and simultaneous positioning with our field-proven S2C acoustic technology. These are our farthest-distance models, designed for reliable, long-range data exchange. Rated for deepest waters, these devices are capable of reaching 10000 m at up to 6.9 kbit/s.
PRO 7/17 dir
7/17 dir is the 7/17 version with a directional, 80-degree beam pattern. Its focused coverage reaches the longest range in near-vertical direction - linking the deepest waters to the surface with the optional full ocean depth rating.

Naming and compatibility notice
Before mid-2025, this model was offered as S2C R 7/17D. Our product naming has been streamlined for consistency - the PRO 7/17 dir modems are acoustically compatible with all existing S2C 7/17 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.
