The logbook built for technical divers — rebreather and trimix dives from your computer, gradient factor analysis, and live sea conditions at your favourite sites.
Dive more. Paperwork less.
QG Diving is the logbook built for technical divers — and just as good for your holiday reef dives. From open circuit on air to staged decompression on a rebreather, it keeps up with the way you actually dive.
BUILT FOR TECHNICAL DIVERS
Closed-circuit dives keep their setpoints, pO2 readings and diluent. Trimix and nitrox mixes, gas switches, ceilings, time to surface and decompression time come straight from your dive computer. Dive with two computers? Every recording stays attached to the same dive, and a dive your computer split in two can be merged back.
SEE WHAT YOUR BODY DID DOWN THERE
Bühlmann ZHL-16C tissue loading and gradient factor analysis for every imported dive, all 16 compartments, with your own GF low/high to replay the dive. Open circuit and rebreather alike. For analysis only: always dive with your own computer and your training.
A LOGBOOK THAT FILLS ITSELF
Connect your dive computer over Bluetooth and your dives import in seconds, or import files from other apps. Every dive becomes a story: site, buddies, photos, a video link and the conditions.
KNOW BEFORE YOU GO
Live weather and sea conditions at your favourite dive sites — wind, waves, swell, tides and water temperature at a glance, with a daily rating so you know it's diveable before you load the car.
YOUR GEAR, CERTIFICATIONS AND INSURANCE — ORGANIZED
Service reminders before your regulator is due, not after. Certification cards read from a photo, with your permission. Pre-dive checklists ready when you kit up.
YOUR DIVING LIFE IN NUMBERS
Depth records, hours underwater, decompression time and TTS, open and closed circuit, air, nitrox and trimix — for a single year or your whole diving life.
