To match a replacement dive computer strap or bungee, identify how your computer attaches, measure the gap between the attachment points and the length you need over your exposure suit, then confirm the part on the maker's own accessory page for your exact model. "Universal" listings that fit the width may not fit the lug shape or mounting holes, so treat the maker's page, not the listing title, as the authority.
Why straps get replaced
Straps wear out, get cut, lose a pin or simply disappear in a gear bag. Silicone and elastomer straps can crack or stretch as they age, and bungee cord can fray or lose its stretch. A visible crack or fray is a reason to stop and fix the attachment before the next outing, not a thing to watch. Nobody can tell you from a photo how long a strap will last, so go by the condition you see and by what the maker's manual says.
The aim of this guide is to get the right part, not the cheapest one. A wrong strap can look fine on the bench and fail at the pin or the retainer. Our bungee mounts and straps guide compares the broad styles; this one is about matching the part to your computer.
Identify how your computer attaches
Computers attach in a few broad ways. Some have fixed attachment points for a conventional strap. Some use a maker-specific connector or a plate. Others are designed to ride on a console or a bungee mount. Your manual and the maker's accessory page show which one you have, and the maker's name for the part is the best search term.
Makers pair accessories with model families. Shearwater's strap kit page lists its silicone strap for the Peregrine and Peregrine TX, and its Perdix 2 page lists a Perdix/Petrel strap kit. Its Teric page lists a band and a webbing strap described for drysuit use. If a kit is listed for a different family, do not assume it fits yours. Our form factors post explains the wrist, console and air-integrated layouts.
Measure before you buy
If the maker no longer sells the part, or you are considering a third-party option, measure first. Photograph the old strap and the attachment points, then measure with a ruler or calipers in millimetres. Write the numbers down and compare them with the listing and, where available, the maker's specification.
The width between the attachment points is the number most listings quote, but it is only one of several. Pin or screw size, hole spacing, the thickness of the strap tail and the shape of the end where it meets the case also decide whether a strap sits properly. If the listing does not give them, ask the seller or choose a maker part. Take pictures of the strap on the wrist, from the side and from above, so you can compare what arrives.
Replacement dive computer straps
Best for: Owners with a known computer model who have measured the old strap
Match the maker's part name and the measurements before ordering. Read the listing for the models it names, and check the return terms.

Length, retainers and thick suits
Strap length matters as much as width. A strap that fits over bare skin may not reach around a thick wetsuit sleeve or drysuit cuff. The Shearwater strap kit page offers a standard and a long size, says the long one suits thicker wetsuits and drysuits, and describes a retainer that lets you loop the excess back over itself. That is a good checklist for any strap: length range, tail management and how it behaves over bulk.
Bungees solve a different problem. They stretch to cover varying thickness and can be re-tied, but they need the right attachment plate or holes on the computer. If your computer is not built for one, do not improvise. Ask the maker or a service centre. The guide linked above compares bungee and strap styles in more detail.
Maker parts, third-party parts and warranty
A maker's own strap is the lowest-risk match because it was made for the case. Third-party straps and bungees can work, but compatibility claims vary in quality, and a listing that says "fits most dive computers" is not a specific claim. Look for the exact models named, read what other buyers describe, and check whether the seller offers returns.
Warranty is worth a thought. Ask the maker or your authorized dealer whether fitting a non-maker strap affects coverage; do not assume. Our gear service guide explains how service routes work. If the computer is secondhand, the checks in the used computer guide apply to the strap too.
Dive computer bungee mounts
Best for: Owners whose computer is made for a bungee or console-style mount
Check that your computer has the plate, holes or attachment the bungee needs. Do not improvise a mount.

What fits what: a quick table
| Attachment style | What to match | Where to confirm |
|---|---|---|
| Maker strap kit for a model family | Model name, strap size | Maker's accessory page |
| Conventional fixed attachment points | Width, pin size, length | Manual; measurements; listing |
| Maker-specific connector or plate | Maker part only, unless the maker says otherwise | Maker or service centre |
| Bungee plate or holes on the case | Plate or hole pattern, cord type | Manual; maker's bungee kit page |
| Console or gauge mount | Mount and hose route | Maker; dive shop |
Fitting it and checking it
Follow the manual for removing the old strap and fitting the new one. Use the right tools; a wrong tool can scratch a case or damage a pin. If the instructions are unclear, take the computer to a dive shop and have them fit it. After fitting, tug the strap and check each attachment point as the manual describes. Keep a spare strap or bungee in the gear bag, matched to the computer, because a strap that fails while travelling is a nuisance you can avoid.
If you are choosing a computer to avoid the problem, our gift-buying check lists the strap and fit points to confirm before you buy.
Spring bar tools and replacement pins
Best for: Owners whose manual describes pin-style strap attachment
Use only if your manual describes this attachment and the part size matches. Otherwise ask the maker or a shop.

Frequently asked questions
How do I know which strap fits my dive computer?
Check the maker's accessory page for your exact model, then compare the part and your measurements with the listing. The maker's page is the authority, not the listing title.
Will a universal strap fit my dive computer?
Maybe, but a universal claim often covers only the width. Check pin size, hole spacing and the end shape, and ask the seller or a service centre if you are unsure.
What strap is best over a drysuit or thick wetsuit?
Makers may sell longer straps or webbing straps for this. Shearwater lists a long Peregrine strap for thicker wetsuits and drysuits. Check your maker's options and the manual.
Can I use a bungee on any dive computer?
No. A bungee needs the right plate or attachment on the computer. Use one only if the maker approves it, and ask a service centre if you are unsure.
Does a third-party strap affect my warranty?
It might. Ask the maker or an authorized dealer before you fit one, and keep the original strap if you can.
