FDS DigiAlti 3: Digital Display Meets LED Light Technology
The Freefall Data Systems DigiAlti 3 (US Patent No. 10,267,630 B2) combines a high-resolution Sharp Memory LCD with a powerful 10-LED LightBar in a single wrist-mounted altimeter. This unique combination delivers both numeric altitude display AND the attention-getting visual alerts of ColorAlti technology—the most powerful digital altimeter ever created for skydiving altitude awareness.
Key Features:
- Sharp Memory LCD: High-resolution digital display, easily readable in direct sunlight
- 10-LED LightBar: Same powerful signaling capabilities as ColorAlti 3
- Bluetooth App Control: FDS Altis app for iOS/Android configuration
- FDS Logbook Integration: Cloud-based jump logging with altitude/speed/temperature graphs
- Robust Aluminum Case: Anodized construction with durable acrylic lens
Who Should Use the DigiAlti 3: Ideal for skydivers wanting both numeric altitude AND visual LED alerts, pilots who prefer wrist-mounted altimeters, jumpers building altitude awareness through multiple feedback methods, or anyone wanting the power of ColorAlti in a digital format.
The LightBar Advantage: The 10-LED LightBar at the top of the display provides ColorAlti’s proven peripheral vision technology. LEDs can display countdowns, color changes, flashing effects, and 33+ different alert combinations—all while the LCD shows your exact numeric altitude.
Configuration & Customization: Five user presets with unlimited alerts per preset. Customize LED colors, effects, flash patterns. Set freefall threshold (default 80mph, adjustable for wingsuit/swoop). Disable freefall alerts below specified altitude for swooping. Landing zone elevation adjustments. All configured via Bluetooth app.
Jump Logging: Syncs approximately 1,000 jumps to FDS Logbook before synchronization required (sync regularly recommended). Records altitude, vertical descent speed, and temperature data. View detailed graphs in cloud-based logbook. Jump data preserved even when battery fully discharged.
Battery & Power: Rechargeable lithium polymer battery: ~100 jumps or 8 weeks per charge. Approximately 2 hours to full charge. Battery life varies based on LED usage (more LEDs lit = more power consumption). Travel mode disables logging for battery conservation.
Mounting Options: Included robust nylon wrist mount. Optional hand mount and elastic mount available separately. Wedge mount + DigiPouch recommended for wingsuit flying.
Technical Specifications:
- Display: Sharp Memory LCD, large numeric altitude readout
- LEDs: 10 individually addressable LEDs (3800mcd peak brightness each)
- Presets: 5 presets, selectable on device during climb
- Altitude Range: -500 to 9,000m MSL (-1,640 to 29,528 ft)
- Resolution: 1m (3.3 ft)
- Sample Rate: 12.5 Hz
DigiAlti vs Traditional Digital Altimeters: Most digital altimeters show only numeric altitude. DigiAlti 3 adds powerful LED visual alerts that work in peripheral vision—combining the precision of numbers with the attention-getting power of lights.
The most powerful digital altimeter ever created. Numbers meet lights.
