i770R Computer — Advanced 4-gas dive computer with Bluetooth connectivity, a bright TFT color display, and hoseless air integration for real-time gas monitoring.

Key features

• Bluetooth connectivity: Share dive stats, location, memories, and photos via the Diver Log+ app for iOS and Android.
• Ultra-bright color screen: Thin-Film Transistor (TFT) display with an intuitive interface for clear readability in varied conditions.
• 3-axis full-tilt compass: Easy-to-read compass graphics with bearing lock, reciprocal heading, and optional compass bar on the primary dive screen.
• Rechargeable lithium battery: Long-lasting and user-rechargeable.
• Hoseless air integration: Real-time gas calculations using a Gas Time Remaining algorithm.
• One-time transmitter pairing: Pair a transmitter once; it remains paired for life.
• Transmitter and gas support: Compatible with up to four transmitters and gas mixes on a single dive; supports Nitrox mixes and up to 3 gases for switching underwater.
• Four operating modes: Air, Nitrox, Gauge, and Free Dive (allows switching between dive modes and free dive).
• Safety and alerts: Audible alarms and a high-visibility LED warning light.
• Updatable software: User-updatable via Bluetooth to receive feature upgrades.
• Water activation and rugged finish: Water-activated start and durable, abrasion-resistant construction.

Functions and data

• Memory and history: Retains settings during battery changes and records up to 24 dives; view total dives, maximum depth, total dive hours, and lowest temperature.
• Navigation: Single-button access to last dive data (maximum depth and bottom time).
• Advanced dive features: Optional deep stop with countdown timer, automatic altitude adjustment, and salt/freshwater selection.
• Watch functions: Alternate time zone, stopwatch, lap timer, daily alarm, and countdown timer.
• Nitrox capability: Supports up to 100% O2 and mixing of up to 3 Nitrox gases (transmitter-dependent).

Transmitter

• Hoseless gas pressure transmission: Transmits tank pressure without hoses.
• Permanently paired: Once set, the transmitter remains paired and will not accidentally pair with other computers.
• User-replaceable battery: Uses a commercially available battery that is user-changeable.
• Available versions: Two transmitter versions are available: Nitrox compatible up to 40% or up to 100% O2.
