Gauges & Accessories

Submersible pressure gauges, combined pressure and depth consoles, button gauges and cylinder pressure check gauges, plus the swivel pins and O-rings that go with them. We stock Apeks, Nautilus, DynamicNord, Shark and Suunto across a range of dial sizes and scales. Check the manufacturer specification for the fitting and scale you need — and if you would rather have a gauge fitted and pressure-checked, our workshop can do that for you.

Choosing a gauge

Dial size is usually the first decision. A larger face is easier to read at a glance in poor visibility; a smaller one stows more neatly against a wing or harness. After that it comes down to the scale you want to read and the maximum reading you need for the cylinders you dive — we quote our own fills in bar. Scales and fittings vary between models, so check the manufacturer specification before ordering.

SPGs, button gauges and check gauges

A submersible pressure gauge runs on a high-pressure hose from your first stage and is read throughout the dive. A button gauge or cylinder pressure check gauge screws straight onto a cylinder valve and tells you what is in it on the surface, which saves rigging a regulator to every stage and stored cylinder just to look. Divers who own several cylinders tend to keep both sorts to hand.

Fitting, hoses and servicing

An SPG connects to a high-pressure port on the first stage, and ports and fittings are not identical across regulators — check the manufacturer specification for yours. High-pressure hoses live in our Hoses and accessories collection. If you would rather not take the job on, our regulator servicing workshop can fit a gauge and pressure-check the result. If you want to understand how your first stage handles pressure in the first place, Understanding Intermediate Pressure in Scuba Regulators is a good read.

Keeping an eye on your gas

A gauge is only as useful as the habit of reading it. Our guide to air planning covers turning cylinder contents into a dive plan you can actually hold to. If a gauge is sticking, misting up or reading oddly, bring it to us rather than diving it — regular servicing catches this sort of thing early, and a gauge you cannot trust is worse than no gauge at all.

Frequently asked questions

A larger dial is easier to read at a glance, which matters in poor visibility or if your close vision is not what it was. A smaller dial is more compact and stows more neatly against a wing or harness. We stock both, plus slimline and button gauges. It is a readability-against-bulk trade-off rather than a performance one — handle them in the shop if you can.

It varies by model, so check the dial described on the product page before ordering. We quote our own fills in bar, so a bar gauge is the simpler match if you fill with us. If you need a particular scale or a specific maximum reading, check the manufacturer specification or ask us and we will confirm before you buy.

A submersible pressure gauge connects to your regulator on a high-pressure hose and is read throughout the dive. A button or cylinder pressure check gauge screws directly onto a cylinder valve and tells you what is in it on the surface — useful for checking a stage or a stored cylinder without rigging a regulator to it. Divers who own several cylinders often end up with both.

An SPG runs on a high-pressure hose into a high-pressure port on the first stage, and it is not a like-for-like swap across every regulator — ports and fittings differ, so check the manufacturer specification for yours. Unless you are confident with the fitting, have it installed and pressure-checked by a technician. Our workshop can do it, and it is a sensible job to combine with a service.
