How to import dives from a Hollis dive computer
No Hollis model in the catalog has a radio, so every transfer goes through a cable and a file. Pick your exact model below for the steps that apply to it.
Hollis models that need a cable
An iPhone cannot open a serial or USB connection to a dive computer. These go through a Mac or PC once, then into SeaLog as a UDDF file.
Hollis downloads, drivers and manuals
The brand is alive under Huish Outdoors but has left the dive-computer market entirely; the software page survives purely as a legacy archive whose newest file dates from 2016.

Worth knowing
- Hollis no longer sells dive computers. Its current instruments page carries only brass pressure gauges, and there is no computers category on the site. The software page exists purely to keep old owners going.
- Everything on that page is Windows-only and frozen in time: HCI for DG02/DG03 is from 2013, HTCI for the TX1 from 2014, and the newest item of any kind is the 2016 Explorer interface. Plan on an old Windows machine or a VM. There has never been a Hollis Mac application.
- Hollis's own link to the Silicon Labs driver points at a retired silabs.com URL that now just dumps you on the Silicon Labs homepage. Use the current CP210x VCP page instead.
- The Explorer interface software is not hosted on hollis.com at all. It downloads from pelagicservices.com, the Pelagic Pressure Systems service host.
- Manuals moved to huishoutdoors.com, which returns 403 to command-line tools but serves normally in a browser; do not read that 403 as a dead link.
- Third-party route: Subsurface and MacDive read the DG02, DG03 and TX1 through libdivecomputer over the same FTDI cable, which is the sane option on macOS or modern Windows. The DG01, DG05 and Explorer are not covered.
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.
