10 Best Pressure & Depth Gauges For Scuba Diving

Where do you start with finding a pressure gauge for scuba diving? 

You might be surprised at how often we see scuba diving experts lost when it comes to finding the right type of equipment that would be deemed ‘techy’. And, it’s perfectly understandable. You’re into scuba as a hobby, you’re probably not here to be told the ins and outs of how these things work. But, it’s good to know what ‘the best’ looks like so that you can make an informed decision when it comes to buying the right pressure gauge for your activities.

And, what do we mean by that? Well, for beginners in particular, you don’t want to jump straight into the most expensive equipment for the sake of it. The expensive stuff can be quite complicated, and they’re not necessary when you can get cheaper versions which are just as good for beginner dives. However, if you are progressing to more challenging locations and require a greater level of detail in monitoring your depth and pressure, then I’ve also included some of the more expert items with literally everything you might need.


Why are pressure or depth gauges so important?

It might sound obvious, but often divers don’t actually fully understand why gauges are so integral to the safety of their dive. The main ‘job’ of the depth gauge is to let the diver know both the maximum depth that they can descend to (and, with that, pressure levels), and also what their actual depth is at the time of viewing.

So, why is knowing this important? Well, used in conjunction with your dive computer, you can calculate how much air you actually have left, whether you’re descending to levels considered dangerous, and ultimately keep a very sharp eye on your primary diving equipment with this otherwise small and life-saving tool.

You’ll need one, but which? This guide is here to help.

When it comes to gauge maintenance, all you need to do to maintain it is to gently wash and soak it with fresh water because it’s attached to your regulator. But when your regulator goes into its annual check with your dive shop, get them to look over your gauges as well. 

When it comes to packing your gauges, make sure to handle them with care and try not to pack them in a spot where heavier items on top of them could damage them.



Cleaning your gauges is simple, just take them out of their boots and wash the gauges gently with fresh water and make sure to scrub out the boots so you can remove any sea salt or debris. If the debris is too difficult to remove with just water, you can buy specific diving equipment cleaners to help remove any debris properly.


Price Ranges

Prices can differ when it comes to pressure and depth gauges. For example, the Mares Mission 1 Compact Pressure Gauge is $100.99 because of its high-quality material and the product’s reliability. But there are other options like the XS Scuba Highland Mini Tech Pressure Gauge, which is at $44.95, but that is because you are just getting the gauge and have to buy the boot and hose separately.


Difficulty Level

Depending on the type of gauge you are looking for, they can vary in difficulty level. You can get pressure gauges with just one numeral to look at with different colour-coded points that are easily labelled and perfect for beginners. 

Or you can get gauges that are for the more professional diver who knows about metric and imperial systems, and those gauges may have more than one dial to look at, making them more complex. 



Pressure and Depth Gauges are an essential part of any scuba divers experience, making sure to keep you safe whilst you dive. They measure your air pressure, and how deep you are going so you can decide when to resurface. They come in many different shapes and sizes, and some even come as a dual pairing saving you space and time. 

Many gauges come with a boot and hose to keep them safe from damage as you dive. The hose can be used to attach to other parts of your gear or attach a compass to it to have all of your equipment in one place.
