Halcyon Symbios Silver Handset Computer

Overview

The Halcyon Symbios Silver Handset Computer is a wireless, slim, glove-friendly dive computer for advanced diving. It handles open circuit and rebreather diving alike, and keeps you up to date in real time on your dive, your team and your decompression. It is sold on its own or packaged with the Symbios Tank-Pod, the Symbios HUD, or both.

Key Features

• Open circuit and rebreather support: Works for open circuit and rebreather diving. A CCR pod links it wirelessly to supported rebreathers.
• Full-colour transflective display: Readable even in direct sunlight without a backlight, with large, easy-to-read numbers. The power-efficient screen extends battery life.
• Simplified, customizable screens: The main screen is kept simple, additional data sits on dedicated pages, and display fields can be customized to your preferences and requirements.
• Team awareness: A dedicated buddy screen shows key data from your dive partner (PO?, oxygen pressure), and in open circuit mode you can watch a buddy's gas supply.
• Bailout handling: Calculates time-to-surface (TTS) for both CCR and bailout. Bailout options are flexible and include switching between CCR and open circuit modes, and single-action bailout control cuts task load.
• Decompression insight: A Gradient Factor chart pictures your decompression, and the computer shows which tissue compartment is leading and how the compartments progress during the dive.
• Training and simulation: On land you can learn every function and run simulated dives with variables such as depth, time, pressure and O2 cells. In the water you can simulate dives and decompression scenarios, so you can practice in shallow environments before real dives.
• Connectivity and profiles: Halcyon lists connectivity with GPS, buoys, DPVs, primary lights, gas analyzers and more. Screen layouts, features and gas configurations are set up before the dive, and profile management adjusts all settings with one press.
