How to import dives from a Deepblu Cosmiq+
The Deepblu Cosmiq+ talks Bluetooth LE, so SeaLog downloads it straight to your phone. No cable, no desktop, no manufacturer account.
Download dives from the Deepblu Cosmiq+
- Wake the computer and put it in transfer mode
Charge or wake the Deepblu Cosmiq+ and open its Bluetooth or PC/upload mode. Most models only advertise for a minute or two, so do this last, right before you pair.
Most units only hold this mode for a minute or two, so do it last, right before you connect. - Open the import hub in SeaLog
In SeaLog, tap the plus button, then Import dives, then Dive computer. Allow Bluetooth when iOS asks. SeaLog never asks for a manufacturer account.
- Pick your model and pair
Choose Deepblu Cosmiq+ from the list. If iOS shows a pairing prompt, accept it. Keep the computer in transfer mode until the download finishes.
The unit only advertises for a short window. If it never appears, put it back into transfer mode and try again straight away. - Download the dives
SeaLog pulls every dive still in the computer's memory, with depth profile, water temperature, gas and surface interval, and skips the ones you already have.
- Check and keep
New dives land in your logbook ready to name, place on a site and tag with the species you saw. Nothing was retyped.
A dive log app for the Cosmiq+
Once the dives are in, SeaLog treats them like its own: a scrubbable depth profile, the site pinned on a map, water temperature, gas and tank, buddies, and the photos from your camera roll matched to the minutes you were underwater. Tag the animals you saw and they go into your species life list. It works offline on the boat and syncs when you are back, and your whole logbook exports to UDDF, CSV or PDF whenever you ask, so nothing is locked in here either.
Deepblu’s own software and drivers
Effectively dead. Deepblu announced in December 2023 that it was pulling its dive-log and media servers offline for lack of paying subscribers, the official app stopped working for users through 2024, and no Deepblu-published app is findable on the App Store today. The COSMIQ+ hardware itself still records dives normally.

Deepblu Cosmiq+: common questions
Why will my Deepblu Cosmiq+ not connect over Bluetooth?
Nine times out of ten the computer has dropped out of transfer mode: it only advertises for a short window, so put it back into Bluetooth or upload mode and try again immediately. After that, check that the battery is not low, that no other app or desktop is already holding the connection, and that Bluetooth permission is granted to SeaLog in iOS Settings. Toggling iOS Bluetooth off and on clears a stale pairing more often than it should.
Do I need Deepblu as well?
No. SeaLog reads the Deepblu Cosmiq+ itself, so you do not need a manufacturer account or a second app in the middle. If you already have years of dives in Deepblu, export them to UDDF once and import that file so your history and your new dives live together.
Does the depth profile come across, or just the numbers?
The full profile. SeaLog stores the sample-by-sample depth, temperature and ascent data, draws it as a graph you can scrub, and can export the whole thing back out to UDDF at any time.
