Buying a Dive Computer as a Gift: What to Check First

Before you buy a dive computer for someone else, check four things: how it will fit their wrist and exposure suit, whether its modes match the diving they are trained for, which app and logbook they already use, and how it charges or takes batteries. If you cannot answer those without guessing, a dive-shop gift card or a smaller accessory is the better gift.

Find out what they already own

Start with what is already on their wrist or console. Ask their dive buddy, look at photos from their last trip, or glance at the gear bag. A diver who already owns a computer may not want a second one from a different maker, because their logbook history, app and any air-integration transmitters are tied to the brand they use.

A diver who rents everything else may love a computer of their own, but the choice is still personal. Many divers learn one interface well and prefer to stay with it. DAN's page on using dive computers advises learning a computer's strengths and weaknesses, and which decompression model it uses, before you buy (DAN). That is a good reason to let the diver have a say in the model, even if you pay for it.

If you want to keep the gift a surprise, ask a question that does not give it away, such as "what would you replace first?" The answer tells you whether the gift is a new computer, an accessory for the one they have, or something else entirely.

Wrist size, straps and exposure suits

Wrist computers sit on straps, and the strap is where fit problems start. A case that is comfortable on a bare wrist may be tight over a thick wetsuit sleeve or a drysuit cuff. Makers often sell longer straps or alternatives for this reason.

Shearwater's strap kit page for the Peregrine is one example. It lists silicone straps in a standard and a long size and says the long one suits thicker wetsuits and drysuits. The maker's Teric page lists a webbing strap described for drysuit use next to a standard band. Other makers differ, so read the page for the exact model.

On the maker's own site, check which strap or mount options exist for that model, whether spares are sold separately, and how the computer attaches. Compare the case size with the recipient's wrist if you can; our small-wrist guide covers compact designs. If they dive with a console or bungee mount, a wrist computer may not suit them at all, and wrist versus console explains the trade-off.

Modes and gas types: match the diver, not the feature list

Computers differ in which gases and modes they support. Some are built for air and enriched air, some are multi-gas, and some include freediving modes. Shearwater's Peregrine page, for instance, calls that model a multi-gas computer. More modes are not automatically a better gift. Each diver configures and uses a computer according to their own training, and a mode they are not trained for is just extra menus.

Ask the diver, or a shop that knows them, what kind of diving they do and what their certifications cover. Then read the maker's specification page to confirm the model supports it. Do not treat a gift as a reason to try any mode beyond that training. Settings, alarms and limits are matters for the manual, the diver's training agency and their instructor, and this page gives no guidance on them.

App, logbook and transmitters

Most current computers can send dive logs to a phone or computer. Shearwater, for example, describes Bluetooth log download through its own app. Before buying, check on the maker's page that the app exists for the recipient's phone and operating system. A computer whose app will not run on their phone is a frustrating gift. If they already keep a logbook in a particular app, check whether the new computer's logs can go there.

Air-integrated gear is the bigger ecosystem trap. Transmitters are generally tied to one maker; Shearwater's Swift transmitter page, for example, describes it as working with that maker's air-integrated computers. A diver with transmitters from one brand would have to replace them to change brands. If their kit includes a transmitter, buy within that range or ask first. Our air-integrated explainer covers the basics.

Charging and batteries

Computers split into rechargeable and replaceable-battery designs, and the difference matters for a gift. The Peregrine page describes a wireless rechargeable battery with a USB-C wireless charging station included, and lists a replacement charger separately. The Perdix 2 page, by contrast, describes a user-changeable AA battery (that page also says the model is no longer manufactured).

For someone who travels, a charger is one more thing to pack and a swappable battery is one more thing to buy. For someone who dives close to home, charging may be no trouble at all. Battery handling and replacement follow the manual, and sealed designs go back to the maker or a service centre. See rechargeable versus replaceable for the practical differences.

A short checklist for the gift-giver

When a gift card is the better call

If you cannot answer most of the table, give a gift card from the diver's dive shop. The shop can fit the strap, confirm the model with them and handle warranty questions. A gift receipt is the next best option if you do buy online, and so is keeping the box and receipt until they have tried it.

Buy new from a seller the maker lists as authorized, and avoid used computers as gifts, since a used unit needs the checks in our used computer guide.
