Large Screen Dive Computers
When you're 30 metres down, the last thing you need is to squint at your dive computer. Large display dive computers are built for real-world readability — oversized, high-contrast screens that put your depth, no-decompression limits, ascent rate, and gas time front and centre, whatever the conditions.
Our range includes large screen dive computers from the world's most trusted brands — Shearwater, Suunto, Garmin, Scubapro, Mares, and Cressi — covering everything from beginner-friendly recreational models to technically capable computers for nitrox, trimix, and CCR diving.
Who are large screen dive computers for?
Large display models are particularly popular with divers who wear prescription lenses underwater, older divers who prefer bigger text, and anyone who dives in low-visibility conditions like UK waters, caverns, or night dives. They're also a smart choice for technical divers who need to scan multiple gas mixes and deco data quickly without misreading a thing.
What to look for
-
Screen size and brightness — look for bright backlighting and AMOLED or colour TFT displays for maximum clarity at depth
-
Air integration — models like the Shearwater Peregrine TX and Suunto EON Core can connect wirelessly to a tank transmitter so your remaining gas is always visible on screen
-
Customisable displays — computers like the Shearwater Perdix 2 let you configure exactly which data fields appear and where
-
Algorithm and gas support — if you're diving nitrox or planning decompression dives, check the computer supports your mix count and preferred algorithm (Bühlmann, RGBM, VPM-B)
-
Battery life — rechargeable vs replaceable batteries is a personal preference; rechargeable is more convenient for travel, replaceable gives you a backup option on remote trips
