Canadian Dive Computer manufacturer Shearwater Research have announced the release of a firmware update for the Petrel and the Petrel 2 in their latest newsletter.

Listing of changes in Petrel Firmware v33

These changes apply to both the Petrel and Petrel 2 unless otherwise noted.

NEW FEATURE: After changing the battery, the current deco tissue loading is shown on the Tissues Restored screen.

NEW FEATURE: On the Tissues Restored screen, a shortcut to reset the tissues is given. If Reset is chosen, a prompt will be displayed to confirm.

Do NOT reset tissues between repetitive dives, as inert gas loading will be lost.

Battery-Changed

The tissues bar graph is now shown on the Tissues Restored screen

CHANGE (Petrel 2 only): Compass mark heading menu moved to reduce button presses. Also, the compass can now be viewed while marking. Operation: when viewing compass a left button press brings up an “Exit Mark” menu. Right press marks compass, Left press exits to main screen. Previously had to navigate to regular menus to mark the compass.

The mark heading command now requires less button presses

IMPROVEMENT (Petrel 2 only):  When a heading is marked, the display now shows the offset angle between the current heading and the marked heading. This is useful for navigating patterns. For example, a box pattern requires turns at 90° intervals, while a triangle pattern requires turns at 120° intervals.

The offset between current and marked heading is now shown (in this example 16°)

IMPROVEMENT (Petrel 2 only): Compass display improvement. The ‘N’, ‘E’, ‘S’, and ‘W’ characters changed to a larger font.

NEW FEATURE: New “Cave” brightness setting. This is even dimmer than Low brightness, and is suitable for very dark environments like caves or night diving.

Cave brightness is very dim and thus best suited for dark environments like caves.

BUG FIX: Fixed problem where gas usage for bottom time segment in dive planner was too low, due to the ascent rate (33 fpm) being used to calculate descent (60 fpm). This problem only affected gas usage calculations and not the decompression schedules.

NEW FEATURE: As a secondary backup to the super-capacitor the deco tissues and clock into permanent memory every 16 seconds when on (every 5 minutes when off). These backups will be used once the super-capacitor is drained.

On the “Bus Devices” page, choose “View” to see more info and setting

NEW FEATURE (DiveCAN Models Only):  Added support for changing settings on peripheral boards.

For example, on the SOLO board (solenoid and oxygen controller) the Solenoid Speed setting can be adjusted. Go to “Bus Devices” page on Petrel to access peripheral boards. Settings viewed here are stored on the peripheral device.

Firmware updates on peripheral boards may be required before settings can be adjusted.

If settings are available, they can be changed here. These settings are stored on the peripheral device.
