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 centre 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 centre.

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.

When storing your NERD 2 please ensure you have rinsed it in fresh water, store in a cool and dry place, and make sure to fully charge it prior to storage.

Try taking the battery out and leaving it out for at least 5 minutes. This should allow the transmitter to reset, and often solves a loss of communications.
