How to import dives from a Crest dive computer
1 of the 1 Crest models in the catalog download straight to an iPhone over Bluetooth. Pick your exact model below for the steps that apply to it.
Crest models that sync over Bluetooth
SeaLog pairs with these directly. No cable, no desktop software, no manufacturer account. Where a model line was sold in both a wired and a wireless generation, its page covers both routes.
Crest downloads, drivers and manuals
Alive and actively shipping: CREST still sells dive computers, still publishes manuals per model, and has migrated everyone onto a current app (Dive Story Pro) after retiring the two older ones.

Worth knowing
- CREST retired both older apps: the plain Dive Story app was wound down around April 2025 and DiveStory+ has not been updated since 2023. Dive Story Pro is the only one still receiving releases.
- Dive Story Pro is quietly the app for three brands on this list at once. It reads the CREST computers, the Deep 6 Excursion and the Scorpena Alpha, because in libdivecomputer all three share the same protocol family.
- The firmware-update blog posts CREST used to publish have been removed; those URLs now redirect to the general support page, so there is no public per-version firmware archive any more.
- Firmware updates are applied through the app over Bluetooth, not by downloading a file to a computer, so there is nothing to install on a PC or Mac.
- Warranty handling is routed through a third-party request form and CREST's Facebook page rather than an email support desk, which is worth knowing before you count on written support.
One logbook for all of it
SeaLog keeps every dive in one place whichever computer it came from, with the depth profile intact, and exports back out to UDDF whenever you want it.
