DiveNET: Sealink acoustic modems offer industry leading performance in a compact, low power demand and affordable solution. DiveNET: Sealink is designed to enable subsea wireless data networking capabilities with cost-effective, long range digital communication.

Sealink-C (Command) is a coded message modem with a fixed signal frequency and subscriber code division supporting up to 40 individual commands to create a point-to-point subsea network of up to 25 devices in a working area of 8,000 m x 8,000 m. Small size, low power consumption and easy integration make Sealink-C an ideal solution for remote operation of target control channels and various actuators, circuit breakers, and other system elements.

Sealink-S (Streaming) provides a transparent transmission channel with speeds of 80 bps to a range of up to 8,000 m (Sealink S) and 560/1200 bps.

Sealink-M (Microlink) is a minuature form factor, multi-mode acoustic modem featuring code command and streaming modes of operation and built-in speed of sound measurement. Microlink modems can also be upgraded to work as a pinger or navigation base station as part of an OEM/DIY acoustic positioning system.

Sealink modems feature an optional built-in depth sensor.

Sealink modems are rated to depth of 300-400 m.
