Computer Accessories

Straps, screen protectors, battery kits, transmitters, mounts and cables for the computer you already own. We stock accessories from Suunto, Shearwater, Mares and Aqualung. Almost everything here is model-specific, so check the model named on the listing against the one marked on your computer. If yours is not named, ask us before ordering rather than hoping it fits.

Match the accessory to the model, not the brand

Dive computer accessories are designed around a specific model. Straps, bezels, screen protectors and mounts from elsewhere in the same range will often look close and still not fit, because lug spacing, case diameter or screen shape has changed between generations.

Every listing here names the models it fits. Check that against the model marked on the back or the face of your computer, and if your model is not named, ask us before ordering.

Batteries and servicing

How a battery is replaced varies from model to model. Some computers are designed for the owner to change the battery using a kit that includes the seals. Others are sealed units, or need checking after being opened. Check the manufacturer specification for your computer before you open it, because the seal is what keeps the water out.

If you would rather not do it yourself, we handle battery changes in store.

Air integration and transmitters

Air integration puts cylinder pressure on the computer screen instead of on a contents gauge. It needs a computer that supports it and a transmitter from the same compatible system, and transmitters do not cross between brands. Check the manufacturer specification, or ask us to confirm the pairing before you buy.

Small parts that save expensive ones

Screen protectors, spare spring bars, strap screws and o-rings are the inexpensive parts that stop the expensive part being damaged or lost. A perished strap or a worn retaining bar is one of the more common ways a computer goes missing on a dive, and both are worth checking as part of your pre-dive routine.

If you are still choosing the computer itself, our guide to choosing a dive computer is the better place to start, because that decision determines what will fit it for as long as you own it.

Frequently asked questions

Straps, screen protectors, bezels and mounts are model-specific. A strap made for one model in a range will not usually fit another model in the same range, even where they look similar.

Check the exact model named on the product listing against the model marked on your computer. If your model is not named, ask us before ordering rather than assuming it will fit.

It depends entirely on the model. Some computers are designed for a user-replaceable battery and we sell the kit with the seals included. Others are sealed units, or need checking after being opened.

Check the manufacturer specification for your computer before opening it, because a badly seated seal is what floods a computer. We also change batteries in store if you would rather we did it.

You only need one if your computer supports air integration and you want cylinder pressure on the screen. Transmitters pair to a specific system and are not interchangeable between brands.

Check the manufacturer specification to confirm that the transmitter and the computer are a supported pairing, or ask us to check it before you buy.

Rinse it in fresh water after every dive, paying attention to the buttons and any charging or download contacts, and dry it before storing.

Check the strap and its retaining bars for wear as part of your kit check. A perished strap or a tired spring bar is one of the more common ways a computer gets lost on a dive, and both are inexpensive to replace.
