A full comparison can be found here: Product Comparison Chart to learn more about the difference between the Peregrine TX and other Shearwater dive computers.

The Peregrine TX charges wirelessly on the included wireless charging pad. Although it may be compatible, we do not recommend third-party wireless chargers.

Yes! Like all Shearwater computers, the Peregrine TX supports decompression diving. The Peregrine TX can be programmed with 3 nitrox gases up to 100% O2, switchable underwater. It also includes a built-in decompression dive planner.

The Peregrine TX does not contain a Tec mode. The Peregrine TX does contain Air mode, Nitrox mode, 3 Gas Nitrox mode, and Gauge mode, which can be used for some types of technical diving.

The Peregrine TX does not come with Trimix capability. However, it can be used in gauge mode as a backup bottom timer to a maximum depth of 120m.

The Peregrine TX uses Bühlmann ZHL16-C with Gradient Factors, one of the most widely used and trusted diving algorithms available. This is the same primary algorithm that is used in all other Shearwater dive computers. The DCIEM algorithm is also available as an additional upgrade.

VPM-B is unavailable on the Peregrine TX. The DCIEM algorithm is available on the Peregrine TX.

Yes, the Peregrine TX has 3 preset conservatism options (low, medium, and high), and a custom conservatism option that allows the diver to manually set their GF parameters. Shearwater advises divers to use caution when adjusting conservatism levels if they don't understand the implications of the change.

No, the Peregrine TX uses Bluetooth® wireless technology to connect to the free Shearwater Cloud app on your desktop, notebook or smartphone. From here you can download your dive logs or update the firmware to the latest version.  

Battery life per charge is up to about 30 hours on medium brightness level.

We expect typical battery life to be several years. Actual battery longevity depends on usage and storage conditions. Generally, lithium battery performance will degrade slowly over time.

The battery can be replaced at authorized service centers.

The turnaround time for replacement is 5 business days after receipt of payment, excluding shipping time. The battery replacement includes inspection, functional testing and pressure testing.

The Peregrine TX contains a 900mAh internal rechargeable lithium-ion battery.  

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

Yes, we will replace the charger under warranty. In the meantime, a third-party wireless charger will usually work in a pinch. 

Shearwater offers a worldwide 2-year warranty on all products. The warranty lives with the unit, not with the original purchaser. This means that whether you buy your unit from our dealer network or second-hand, the warranty will still be effective.

Shearwater will, at its sole discretion, repair or replace defective products covered under warranty.

Unauthorized repairs, accidental damage, or negligence are not covered by the warranty.

The warranty covers included accessories such as chargers and straps.

Do I need to register my computer for warranty?

No. The warranty is linked to the computer’s unique serial number.

Who do I contact if my computer needs a repair?

You can contact our support team directly at info@shearwater.com or fill out the RMA form (Return Merchandise Authorization) here: https://www.shearwater.com/rma-request-form/

You may also contact your closest authorized service center directly using the contact details at the bottom of the page.

Please do not return any products without first obtaining an RMA from the relevant service center.

How much will my out-of-warranty repair cost?

A computer that comes in for an out of warranty repair will need to be disassembled to properly test the components to determine the failure. Once the failure has been determined, we will be able to accurately calculate an estimate for the necessary repairs. Please note that to prevent usage of potentially non-functioning computers, if you decline the repairs, and wish to have the computer returned to you, it will be returned disassembled.

How long will the repair take?

Shearwater and its authorized service centres aim to finish warranty repairs and authorized out of warranty repairs within 5 working days of receipt.

Delays in repair time may result due to holidays, parts delays, and/or the requirement for the computer to be repaired at a different location.

Please contact the relevant service centre for a more accurate timeframe.

What is Shearwater’s service shipping policy?

You are responsible for the cost of sending in the computer for repair. As a reminder, do not send your computer to any repair centre until you have obtained an RMA from that repair centre. For in-warranty repairs, the computer will be shipped back at no charge. For out of warranty repairs, the return shipping charge is included within the repair estimate. If you have an out of warranty repair that you choose to decline, you may ask to have the service centre destroy it or ship it back at your cost.

How often should I have my computer serviced?

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

Does the warranty cover the rechargeable battery in my Teric/Peregrine?

It is important to follow the directions for charging/storage in the computer’s manual to ensure peak battery performance.

If the battery is not meeting performance specifications within the 2-year warranty period, it will be repaired free of charge. Variations to battery lifespan can be expected due to operating at extremes of the rated specification, such as high environmental temperatures or repeatedly fully discharging the battery. 

Battery Leaks

Damaged caused by battery leaks in dive computers that use a user changeable battery is not covered under warranty. Shearwater recommends the use of a lithium battery such as the Energizer Ultimate Lithium 1.5v battery to reduce the chance of battery leaks. Leaving AA batteries (especially alkaline batteries) in devices for extended periods of time significantly increases the chance of damage from a battery leak.

DEMO & PRO Computers

Please note that the warranty with our Demo & Pro model computers are only available to the original purchaser. For demo models, this means the authorized demo centre that purchased the computer. For Pro models, this extends to the original instructor/dive professional that was confirmed at time of purchase. This warranty is absolutely non-transferrable as these models are not intended for resale.

Repairs/service can be performed on Demo and Pro models, but if you are not the original owner, there will be a cost for the service.

These guidelines apply to standard Shearwater products only and any governmental products, including military, commercial, and public safety, may be subject to their own warranty conditions – please consult your representative for further information.
