FAQ

1.5V non-rechargeable lithium batteries like the Energizer Ultimate Lithium batteries have the best overall performance characteristics for use in the Perdix 2 and Petrel 3.

Vibration functions will only work with these as well as 3.7V lithium rechargeable batteries.

Energizer Ultimate Lithium Batteries are much less likely to leak and cause computer damage. These batteries come with a ""No Leak Guarantee"" https://www.energizer.ca/about-batteries/battery-leakage#:~:text=Energizer%C2%AE%20Ultimate%20Lithium%E2%84%A2%20Batteries%20are%20GUARANTEED%20NOT%20TO,383%2D7323%20for%20return%20instructions.

White text takes up to three times as much power to display on the dive computer, dramatically reducing battery life.

All AMOLED's will experience some burn in over time. This is the appearance of a ghostly image on this display from previous images. The more the computer is used, the more burn-in will occur. We don't expect the burn-in to significantly affect user experience and feel that the added contrast and brightness provided by the AMOLED is far superior even with some burn-in over time.

The Petrel 3 supports up to 4 transmitters along with all of our AI enabled computers.

Yes. Both the Perdix 2 and Petrel 3 will work with the Legacy transmitters.

The Petrel 3 does not have recreational modes for DiveCan monitors, but it does for all other models.

No. The Petrel 2 cannot be upgraded. However, if you have a older style Petrel without a titanium surround, please contact your nearest Shearwater Service Centre for your options on adding this as a part of a general computer maintenance service.

No. Shearwater does not operate a trade in program. Contact your local Shearwater dealer for pricing and availability of a Petrel 3.

The Petrel 3 comes with a strong customizable vibration alert system. This is more effective than sound which can be difficult to hear when diving with a hood, or ascertain which computer is sounding an audible alarm when diving in a small group.

No. Your new Shearwater computer comes with a 2 year warranty from the date of purchase from your Shearwater dealer. The warranty lives with the computer rather than the diver and there is no need to register it with us. We suggest retaining your proof of purchase.

We strongly recommend that if you are not diving your Shearwater computer for an extended period of time, that you remove the battery to avoid the leaks and damage that can happen in any electronic device. Your dives and data is securely stored on the computer, even when the battery is removed. For more information on battery removal, see the Petrel 3 instruction manual for your particular model.

Shearwater recommends service of your dive computer every 2 years by an authorized service centre.

The Shearwater Petrel 3 should be stored in a clean, cool and dry environment. Do not allow salt deposits to build up on your dive computer. Wash your computer with fresh water to remove salt and other contaminants. Do not use detergents or other cleaning chemicals as they may damage the Petrel 3 dive computer. Allow to dry naturally before storing. Do not wash with high pressure water as it may damage the depth sensor. Store the Shearwater Petrel 3 upright and out of direct sunlight in a cool, dry and dust free environment. Avoid exposure to direct ultra-violet radiation and radiant heat. Do not store batteries in the Petrel 3 for long periods (several months). Batteries can and do leak, so don’t risk your expensive computer on a simple task like removing batteries. Dead batteries are at a higher risk of leaking.

The standard decompression model is Bühlmann ZHL-16C with Gradient Factors. Also, the VPM-B decompression model and DCIEM is available by purchasing an unlock code. More information can be found in the Petrel 3 manual. Recommended reading is "Clearing up the Confusion About Deep Stops" - Eric C. Baker, P.E.

In Gauge Mode the Petrel 3 does not know what gas you are breathing and therefore cannot track the inert gas tissue loading.

While almost any kind of AA battery will work with your Shearwater Petrel 3, 1.5V lithium batteries like the Energizer Ultimate Lithium work best. This battery type performs well in a wide temperature range and is much less likely to leak and cause damage to your dive computer.
