How to transfer dive logs from a Ratio iDive 2 Reb to an iPhone
The Ratio iDive 2 Reb exists in both a wired and a Bluetooth LE generation. Try the wireless download first, and if your unit never appears, the cable route further down brings the same dives across.
Download dives from the Ratio iDive 2 Reb
- Wake the computer and put it in transfer mode
Charge or wake the Ratio iDive 2 Reb 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.
- 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 Ratio iDive 2 Reb from the list. If iOS shows a pairing prompt, accept it. Keep the computer in transfer mode until the download finishes.
- 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.
If it never shows up: the cable route
The wired generation of the iDive 2 Reb has no radio at all, so there is nothing to pair with. It goes through a computer once, and after that you can log straight into SeaLog on the boat.
- Connect the Ratio iDive 2 Reb to a Mac or PC
Use the serial cable made for the Ratio iDive 2 Reb, not a generic charging cable: the data pins differ. An iPhone or iPad cannot open this kind of connection at all, so this step has to happen on a computer.
- Download the dives with desktop software
Read the computer with Ratio DC Manager or Subsurface. Subsurface is free, open source, runs on macOS, Windows and Linux, and supports this model.
- Export the dives as UDDF
Export the whole logbook to a UDDF file. UDDF is the open dive-log exchange format and keeps the full depth profile, not just the summary numbers.
- Get the file onto your phone
AirDrop it, drop it in iCloud Drive, or email it to yourself. Anything that lands the file in the iOS Files app works.
- Import it into SeaLog
In SeaLog, tap the plus button, then Import dives, then UDDF file, and pick it. Every dive arrives with its profile, and duplicates are skipped.
A dive log app for the iDive 2 Reb
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.
Ratio iDive 2 Reb: common questions
Does the Ratio iDive 2 Reb have Bluetooth?
It depends on the generation. This model line was sold in both a wired version and a later Bluetooth LE version, and they look almost identical. The quickest way to find out which one is on your wrist is to try the Bluetooth download first: if the computer never shows up while it is in transfer mode with a fresh battery, yours is the wired one and the cable route below is the way in.
Why will my Ratio iDive 2 Reb 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.
Which cable and drivers do I need on a Mac?
Use the Ratio interface cable made for this model, not a generic charging cable: the data pins differ. Most of these cables are USB-to-serial and need the driver for their chipset on macOS, usually Silicon Labs CP210x or FTDI. Install the driver, reboot, and the port appears to the desktop software.
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.
