High-speed mid-range communication and positioning for depth-to-surface operations
PRO USBL 42/65
The PRO USBL 42/65 transceiver is a PRO modem with a built-in USBL antenna for combined communication, navigation and positioning with our field-proven S2C technology. With the highest bitrate in the PRO product line, it supports fast data links up to 31.2 kbit/s over 1000 m, ensuring reliable performance for depth-to-surface operations.
PRO USBL 42/65
42/65 offers wide-angle coverage with its 100-degree beam pattern. It is suitable for USBL tracking and fast data transfers in slanted and vertical directions, such as from the seafloor to the surface.

Naming and compatibility notice
Before mid-2025, this model was offered as S2C R 42/65 USBL. Our product naming has been streamlined for consistency - the PRO USBL 42/65 modems are acoustically compatible with all existing S2C 42/65 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.
