S2C Beacons

Underwater Acoustic Modem

Any S2C R underwater acoustic modem can be configured as an S2C beacon - a compact battery-powered device with built-in acoustic release mechanism and floatation collar.

With EvoLogics' patented S2C technology, the beacon is a great communication and positioning performer, optimized for short- and mid- term deployment and easy recovery back to the surface. As a transponder for LBL or USBL positioning, an underwater communication network or relay chain node, the S2C beacon can benefit multiple marine applications.


Applications include

  • Transponder for LBL and USBL positioning

  • Autonomous relay station

  • Autonomous underwater network node
