FAQ
ยังมีคำถามอีกหรือไม่? เรามีคำตอบให้
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.

We are sorry that you are having a problem with your dive computer that can't be resolved with our FAQ’s. If your dive computer needs some kind of repair, simply email us at info@shearwater.com to initiate the process.
Please include your name, address and phone number, description of your problem, your unit model, S/N and Firmware Version. We’ll get you an RMA number and instructions on how to send your computer in for repair. Please do not return your computer to us or any of our service centers without an RMA number.
To find your S/N and firmware, turn on your computer (unless it won’t turn on) and from the main screen press the right side button 8-10 times until you see the S/N displayed (lower left) and Firmware (lower right) of the screen.
The NERD is a full featured technical decompression dive computer. If you are familiar with the Shearwater Petrel or Predator, then you will be familiar with the NERD.
The NERD offers the same functionality and mode options as the Petrel or Perdix but does not run the same software version of firmware. You can read the latest firmware updates to the NERD by clicking here. The NERD has a full-colour Mini-LCD display with the same resolution as the Petrel.
With the NERD, for the entire dive, you will see depth, time, decompression stops, and PPO2 readings all with a quick glance. Everything you need to know stays within your line of sight.
The NERD image appears 12 feet (4m) away. If your vision is corrected for 12 feet away, then you can read the NERD.
Although the NERD is located very close to your eye, you do not need near-vision correction. That is, bifocals or reading glasses are not needed nor wanted. The NERD’s optics make the screen appear further away than it actually is.
So the answer is maybe. You need to be able to see 12 feet away. Since you should be diving with correction at this range, most divers will be able to use the NERD. Note that a mask with bifocal near vision correction may cause problems with the NERD.
The NERD display appears about the same as a 32” TV would from 12’ away (a 81cm TV from 3.7m for the metrically inclined).
If you have used a Petrel or Predator (both 2.4” displays), the NERD screen appears the same size as if they were held 1 foot (0.3m) away from your eye. Most divers have no problem reading a Petrel or Predator from several feet away, so the NERD is very easy to read.
The NERD is typically placed to one side, either in the lower or upper range of vision, and so only partially blocks one eye.
Your brain does an amazing job of combining the information from your eyes and filling in missing information. As such, when you choose to look at the NERD display you will see it, but it will not seem to block much of your vision when you look away. It almost seems as if you can see through it.
If you only have vision in one eye, then unfortunately the NERD will probably block too much of your vision to be usable.
The NERD has two piezo-electric buttons located on the sides of the eyepiece. Pressing these buttons allows editing settings, changing gases, etc.
The button type and user interface are the same as on the Petrel and Predator dive computers.
There are two issues for compatibility: Mounting and PPO2 monitoring.
Mounting:
Compatible with all rebreathers.
The universal nylon strap mount makes the NERD compatible with every rebreather we have tried.
If you have any questions regarding mounting to a specific rebreather model, contact us and we’ll try to help. Note that other constraints (BOV access, other HUDs, etc.) should be considered when choosing a mounting position for the NERD.
If you don’t like our mounting strap, it detaches leaving a simple dovetail mount for customized solutions.
PPO2 Monitoring:
The NERD has two modes of operation for rebreather divers.
- Internal PPO2 – constant setpoint
In this mode the NERD assumes the rebreather is maintaining setpoint at a user selectable level (e.g. 0.7 or 1.3 ata).
All rebreathers that run fixed setpoints (most closed circuit models) are compatible with this mode.
- External PPO2 monitoring
This is where the NERD really shines. Having PPO2 values from 3 oxygen cells displayed in your vision for the entire dive is a great safety advancement. Always know your PPO2.
The NERD is sold with the standard 7-pin Fischer connector (103 size) for connection to oxygen cells. Any rebreather (closed or semi-closed circuit) that uses compatible O2 cells and can use a cable with Fischer connector is compatible with this mode of operation.
The NERD is mounted on an articulating arm that can adjust height, angle, and distance to account for physical differences between different divers.
The arm is easy to adjust without tools, but holds its position once set. During dive entries in high surf, the NERD may get knocked around a little, but is easy to reposition once underwater and things have calmed down.
Yes, the NERD can be used for Open Circuit diving. It has the same OC Trimix decompression capabilities as the Shearwater Petrel.
However, Shearwater Research does not currently provide a standard mount for Open Circuit diving.
The challenge for non-rebreather diving is where to mount the NERD. The rebreather mount can be removed, leaving a simple dovetail mount that can be adapted to other mounting methods.
No, there is not currently an Air Integrated (AI) model.
Please see our troubleshooting section here.
To purchase the VPM-B upgrade you can contact any dealer from our dealer network, provide them with your serial number, and request to purchase the unlock code.
We recommend you remove alkaline batteries from your unit if you intend to store it for an extended period. Alkaline batteries have a tendency to leak when they have fully discharged.
The name of the o-ring used is AS568-112. The size of this o-ring is 1/2" ID by 3/32" width. This is the same o-ring used in the majority of DIN regulators (not Apeks however).
You can use replacement o-rings made of either nitrile, EPDM, silicone or viton. Be sure to use a lubricant compatible with the o-ring material selected. We recommend a Shore 70A durometer, however both harder and softer will work.
To improve the sealing performance and O-ring life span, the battery compartment O-ring gland design has been changed from a crushed gland to a radial gland. Identification of the new radial cap can be made by reading this article. All units being shipped from our factory currently have a radial battery cap.
