A modern diver's telephone station built using the latest technical solutions. Besides two-way voice communication, the station determines the diver's position underwater (using RWLT buoys as the navigation base)

  • Autonomous operation of up to 8 hours (mixed mode) / up to 20 hours (receive only)
  • Compatible with most analogous systems (OTS, Ocean Reef, etc.)
  • Compact: 106×95×55 mm, weight 0.6 kg
  • Built-in voice activity detector
  • Acoustic communication range of up to 1000 m
  • Built-in diver location function

An extremely reliable solution

The device has no openable parts that could leak: there is no way to forget to latch the housing, damage a switch, or fail to tighten a connector — our device simply has none of these. Battery charging and device configuration are performed wirelessly.

01

The simplest possible control

RedPhone switches on automatically when immersed and operates in Push-to-Talk (PTT) mode — reception runs continuously, while transmission is active only while the RedButton is pressed. After each voice message, the station transmits a navigation signal that determines the diver's position underwater.

02

High-quality acoustic communication and accurate object positioning

We apply broadband hydroacoustic communication technology and digital signal processing across all of our systems. This provides reliable protection against interference even in poor conditions (for example, in shallow water), and enables features unavailable in other systems — in particular, underwater diver positioning.

Order RedPhone-DX

RedPhone-DX is supplied as part of the RedPhone system. RedPhone system users can purchase RedPhone-DX separately, as a spare part, to extend their kit, or to replace a malfunctioning station
