Mares Genius Firmware Update Updated May 2026
If you own a Mares Genius dive computer, you may have seen or heard about a recent firmware update. Whether it popped up during a dive-shop check-in or appeared in your device’s software updater, firmware updates like this can be easy to overlook — but they often include important fixes, safety improvements, and new features that impact how you plan and execute dives. Here’s a clear, friendly breakdown of what the “Mares Genius firmware update updated” means, what likely changed, and what you should do next.
Users reported that the vibration motor would either drain the battery unnecessarily or fail to trigger during emergencies. The latest update introduces adjustable intensity levels for haptic alarms, a feature requested since the unit’s launch.
Performing a Mares Genius firmware update requires a PC or Mac (mobile updates are currently only for log viewing, not firmware flashing). Here is the updated process for 2025.
One crucial note for users performing a Mares Genius firmware update updated from a very old version (e.g., v1.0 to v2.15): You cannot skip major versions.
If your Genius is running v1.05, you must first update to v1.20, then to v2.00, then to v2.15. Jumping directly corrupts the bootloader. Check the Mares forum for intermediate patch files—these are not always on the main download page.
Treat firmware updates as important maintenance, not optional extras. Read the official release notes, back up logs, fully charge your device, and test the device after updating. If you’re unsure about how a change affects your diving profile, ask a qualified instructor or contact Mares support.
