Not sure which setup is right for you?
Take Our QuizYour dive computer is the most important piece of kit you'll strap on. It's tracking the nitrogen in your blood, making sure you don't turn into a fizzy drink. In British waters—where you can't see your hand in front of your face half the time—you need a screen you can actually read and a battery that doesn't give up when it gets a bit chilly.
Why UK Diving Is Different (And Why Your Mate's Tropical Computer Might Kill You)
Let's be honest: UK diving is not the Maldives. Water temperatures hover around 6°C in February (that's "why did I take up this hobby?" cold) and peak at maybe 16°C in August (still Baltic, to be fair). Visibility averages 3-10 metres on a good day. Sometimes you're basically diving in a bowl of pea soup.
This means you need a screen you can read when it's darker than a Wetherspoons at closing time. Bright OLED or colour displays are your friend here—basic LCD screens are about as useful as a chocolate teapot when you're suspended in murky green water wondering which way is up. The Shearwater Peregrine and Suunto D5 are brilliant in these conditions—you can actually see the numbers even when visibility is measured in "arm lengths."
And batteries? In cold water, alkaline batteries are about as reliable as British rail. Lithium batteries handle the cold much better. Better yet, get a computer with user-replaceable batteries—you'll save a fortune on service centre fees, and you won't be stuck in Oban waiting three weeks for your computer to come back just so you can finish your holiday dives.
Entry-Level Options (Around £200-350)
The [Mares Puck Pro](https://www.amazon.co.uk/dp/B00N2JQ7CI?tag=divegearadvice-21) (around £200) is like a reliable hatchback—it gets you where you need to go without fuss. Clear display, simple operation, nitrox capable if you decide to get fancy later. It's an honest computer that does the essentials well. Perfect if you're still in the "is this hobby worth freezing my bits off?" phase.
The [Cressi Leonardo](https://www.amazon.co.uk/dp/B00KWL8NM2?tag=divegearadvice-21) (around £180-220) is similar territory—intuitive, decent battery life, minimal learning curve. Both are solid choices for new UK divers who aren't ready to drop serious cash on something they might accidentally leave on a charter boat.
The [Suunto Zoop Novo](https://www.amazon.co.uk/dp/B01DUJQ3SI?tag=divegearadvice-21) (around £200-250) sits at the top of entry-level—bigger display, more data. Its algorithm leans conservative (translation: it'll nag you to surface before your mates), which is actually quite sensible for UK multi-dive weekends where you're doing three dives a day in cold water.
Mid-Range Excellence (Around £350-600)
The [Shearwater Peregrine](https://www.amazon.co.uk/dp/B08MQDXB2V?tag=divegearadvice-21) (around £450) represents the sweet spot for UK diving. Brilliant display, user-replaceable battery, and Shearwater's proven algorithm. Divers consistently praise its visibility in British conditions. This is what most experienced UK divers recommend.
The [Suunto D5](https://www.amazon.co.uk/dp/B07HDKTPMS?tag=divegearadvice-21) (around £500-550) offers colour display and wireless connectivity for logging dives. The compass is useful for UK navigation where visibility limits visual references. Smart watch aesthetics mean you might wear it daily.
The [Garmin Descent G1](https://www.amazon.co.uk/dp/B0B3QLXQMR?tag=divegearadvice-21) (around £400-450) combines dive computer with smartwatch features. GPS surface tracking is useful for UK shore diving where exit points matter. Battery life exceeds most competitors.
Premium Options (Around £600+)
The [Shearwater Perdix](https://www.amazon.co.uk/dp/B01N9GQHXN?tag=divegearadvice-21) (around £700-900) is the choice for serious UK divers progressing toward technical diving. Multiple gas support, customisable display, and bulletproof reliability. Many UK wreck divers consider it essential.
The [Suunto EON Core](https://www.amazon.co.uk/dp/B07HDKTP9V?tag=divegearadvice-21) (around £650-750) offers similar capabilities with Suunto's ecosystem integration. Both are overkill for recreational diving but justify themselves if you're logging 50+ dives annually or planning technical progression.
Wrist vs Console
Wrist computers dominate UK diving now. They're accessible, visible, and don't dangle. Console computers still exist but add clutter in already equipment-heavy UK diving. Most divers find wrist-mount more practical.
Air integration adds £200-400 to cost. It eliminates your SPG but adds a transmitter failure point. Many UK divers prefer traditional gauges as backup, especially in cold water where electronics face extra stress.
Our Recommendation
For most UK divers, the Shearwater Peregrine offers the best balance of features, reliability, and value. Its display cuts through murky British waters, the battery handles cold, and the algorithm suits our multi-dive patterns. Around £450 is money well spent on safety equipment.

Start the QuizFrequently Asked Questions
What features should a dive computer have for UK diving?
For UK diving conditions, look for a dive computer with excellent visibility in low light (OLED or colour screen), cold water battery performance, nitrox compatibility, and conservative algorithms suitable for our 6-16°C waters. Models like the Shearwater Peregrine and Suunto D5 excel in UK conditions with user-replaceable batteries and bright displays.
Do I need a dive computer for UK recreational diving?
While not legally required, a dive computer is highly recommended for UK diving. British waters often involve multiple dives per day on wrecks and reefs, making accurate no-decompression limit tracking essential. Most BSAC and PADI instructors in the UK consider a personal dive computer standard equipment for qualified divers.
What is a good budget for a dive computer in the UK?
Entry-level dive computers suitable for UK waters start around £200-300 (like the Mares Puck Pro or Cressi Leonardo). Mid-range options with better displays and features cost £300-600 (Suunto Zoop Novo, Shearwater Peregrine). Advanced technical computers range from £600-1200. For UK recreational diving, the £300-600 range offers the best value.
Are air-integrated dive computers worth it for UK diving?
Air-integrated computers (showing tank pressure) are convenient but add £200-400 to the cost. For UK shore diving where you carry all your gear, they reduce clutter by eliminating a separate SPG. However, many UK divers prefer the reliability of a traditional pressure gauge as a backup, especially in cold water where battery performance can be affected.
