How to import dives from a Aqualung dive computer

Worth knowing

• Aqualung does not write its own dive computer software. The hardware is built by Pelagic Pressure Systems, so everything (apps, drivers, guides, compatibility lists) lives at ediverlog.com, while aqualung.com only links the phone app and hosts the manuals.
• Aqua Lung Group was placed under insolvency administration in May 2025 and acquired by HEAD in June 2025. The evidence that the software survived the handover is concrete: the DiverLog+ App Store listing is now published by Head Watersports S.p.A. and was updated on 30 October 2025, and aqualung.com now sits inside the HEAD Group brand family.
• Two generations, two completely different programs. Bluetooth models (i200C, i300C, i330R, i330R Console, i470TC, i550C, i750TC, i770R) use DiverLog+ on a phone. Cable models (i100, i200, i300, i450T, i550) use the old DiverLog desktop program plus a proprietary clip-on USB cable. The i750TC and i770R are the only two that work both ways.
• The desktop side is effectively abandoned. DiverLog for Mac is gone from the Mac App Store (the vendor's own link, id540107482, returns 404), and the vendor's pages mark both the Mac and Windows Full editions as Discontinued. Only the free Windows DiverLog Lite installer still downloads.
• The classic DiverLog mobile apps are dead too. All four store links printed on ediverlog.com return 404: iOS id683518274 and id1091923188, and Google Play com.pelagicnet.diverlog.android and .lite.
• The i450T is the worst-off model in the range. It is not in the DiverLog+ compatibility list, and the classic mobile app that covered Aqualung is delisted, so its only remaining route is a Windows PC running DiverLog Lite with the USB cable and the 2002 Design driver.
• Manuals for several discontinued models (i200, i300, i450T, i550, i750TC) are no longer published on aqualung.com. The Owner's Manuals page lists only Universal, i100, i200C, i300C, i330R, i550C and i770R. The i470TC manual is still reachable on Aqua Lung's own Plytix product CDN, but the others are only on third-party manual sites now.
• Windows needs the right driver per model, and they are not interchangeable: FTDI CDM for the i750TC and i770R, and a 2002 Design USB download-interface driver for the i100, i200, i300, i450T and i550. macOS uses the FTDI driver for all of them, with a separate package for 10.13 and older.
• DiverLog exports single dives as DAN DL7 (.zxu) into Documents/PELAGIC/Export/ZXU, and whole logs as .dlg. UDDF is not offered anywhere in the Aqualung toolchain, so a UDDF-based importer will have to accept DL7 or read the app's own files.
• DiveCloud (divecloud.net) is Pelagic's cloud backup and needs a free account; desktop synchronisation to it was historically tied to the paid Full licence that is now discontinued.
• aqualung.com is served from Vercel behind a bot challenge that answers plain curl with HTTP 429 no matter the headers. The three aqualung.com URLs above were verified by loading them in a real browser and reading Navigation Timing responseStatus, which returned 200 for each. Every other URL in this entry was verified with curl and returned a plain 200.
