It’s all very well having a regular old dive computer for deco time, depth and safety stop readings…
…but an air integrated dive computer also tells you how much air remains in your tank (i.e. tank pressure) via a wireless transmitter.
This is an absolute game-changer – it’s so much easier seeing your remaining air on a dive computer than it is having to pull out the pressure gauge every time you want to check it.
In this epic guide of awesomeness, we’ve provided firsthand reviews of the best air integrated dive computers available in 2025.
Dive down to the QUICK ANSWER for a rapid breakdown of each model of air integrated dive computer with links to view on Amazon or scroll down further to read our detailed reviews.
Some air integrated dive computers also show your air consumption rate and use this to provide an AI prediction for how much air time you have remaining.
In my own experience, having an air integrated dive computer leads to a much greater awareness of one’s air consumption rate; this teaches you to control it more carefully and thus makes you a better diver.

What the Hell is Air Integration in a Dive Computer anyway?!
In case you’d like to know a little more about what it means for a dive computer to be air integrated – you’re in the right place!
Not all dive computers feature air integration technology. But of those that do, they still require a (separately purchased) wireless transmitter – also known as a tank pod, air integration pod or air integration transmitter.
The air integration transmitter communicates information regarding tank pressure (how much air is in the tank) with the dive computer – it usually does this through radio frequencies although it can also be via sonar technology.
Let’s take a look at one of those air integration transmitters below, in this instance a Suunto air integration transmitter aka Suunto Tank Pod:
Seems kinda unassuming don’t it?! Almost a surprise you pay several hundred bucks for it, but this is the very thing that allows your dive computer to show you how much air you have left in your tank – and more!
That serial number at the bottom is pretty freakin’ important by the way. When it comes to pairing your dive computer with your air integration transmitter, you’ll want to pair it with the right serial number – otherwise you could end up pairing it to someone elses transmitter – awkward!
Some air integrated dive computers boast of being able to pair to multiple transmitters – in theory this would allow a dive instructor to keep tabs on multiple students air. However, in reality it’s highly unlikely that a dive centres is going to fork out all that money just so their instructor can monitor everyone’s air like that.
Generally speaking, a transmitter produced by one scuba diving gear manufacturer – e.g. Suunto can be paired with any of that brands dive computers (so long as they’re models that feature air integration). For example the Suunto Tank Pod can pair with a Suunto D4i, Suunto D5, Suunto Eon Core, etc. But it can’t to be able to pair with a Garmin MK2i dive computer.
After the air integration transmitter is connected to your dive computer, it’ll usually automatically do this every time you turn your dive computer on. But be sure to check this in settings before you dive!
Let’s backtrack and take a quick look at the sort of box-content you can expect to receive when you buy an air integration transmitter – in this case a Suunto Tank Pod:
So – you get the wireless transmitter / Suunto Tank Pod, an information leaflet, a warranty and in that little clear baggy you see there are a pair of flow restrictors – the long one is for when you’re connecting the air pod to a high pressure hose (if you have a console dive computer).
The short one is for when you’re connecting the transmitter directly to the first stage of your regulator because you have a wrist dive computer – this is more likely as most dive computers are wrist dive computers.
How to Connect Dive Computer Wireless Transmitter to Regulator First Stage:
We’re glad you asked! Check out the little movie below for a full demonstration. With catchy electro.
So…if you’re going to use an air integration transmitter, you’ll want to have your own scuba regulator as it’s a little fiddly to attach and most dive centres probably won’t want you to do this to their own rental regulators. If you don’t yet have your own scuba regulator – check out our best scuba regulator reviews here!
The information leaflet explains how you can connect the tank pod to your regulator (or high pressure hose) but there’s also an online guide on attaching a Suunto Tank Pod here.
Check out the image below to see what it looks like when an air integration pod is connected to the first stage of a regulator:
After attaching your tank pod to your regulator or high pressure hose, you’ll really want to avoid it getting knocked – it’s not flimsy but it also ain’t ultra tough. I highly recommend buying a hard case for your scuba diving regulator to keep everything safe – here’s a link to the one I use!
By the way, most air integration transmitters run on user-changeable lithium batteries that normally last 150 – 200 dives.
Ok, moving on… once you’ve attached your wireless transmitter to your regulator (or possibly high pressure hose), and connected it to your dive computer, you will be able to view the air integration information on your dive computer. Let’s take a look at several screenshots of air integration info displayed on the might Suunto D5:
On the lower third of the Suunto D5’S display it’s showing 100 tank bar remaining. If you’re wandering where that beautiful coral in the background was taken by the way – I snapped these photos with my Suunto D5 whilst diving in the red sea – it was awesome! Ok – next photo:
Now the lower third shows air consumption. This is really cool because not only does it let you know how fast you’re getting through air on a dive, it’s also recorded in the logbook. This means you can go through your various dives and see if your air consumption is improving – or getting worse! I love this!!
To cycle between different sets of air integration info – e.g. how much air remains or air consumption rate, you up simply press the lower button of the D5. However, the manner in which you pull up different air integration info will vary between dive computers – but it’s usually ultra simple. Let’s check out yet another photo:
Now we see that in the lower third of my Suunto D5’s display, it is giving remaining air time – i.e. how long before my tank is totally empty! In this instance, it’s telling me I have 25 minutes of remaining gas time – which is based on my air consumption so far throughout the dive.
This is another super handy feature! It uses intelligent Ai to give this prediction. Of course, it can’t account for unforseem circumstance. Perhaps a horny mermaid is about to swim out of the abyss and grab my leg to pull me down – this will likely elevate my heart-rate somewhat and cause me to get through my remaining air quicker than the D5 anticipated. The remaining gas time is just an estimate.
And that’s pretty much it in terms of air integration tech. Depending on which model of dive computer you have, you’ll find that navigation through different air integrated related sets of data may vary whilst very simple air integrated dive computers may only give you remaining and air consumption but not show remaining air time. We’ve mentioned which models of air integrated dive computer can and can’t do this in the reviews above.

A moment’s thought: Diving is not only about exploration, there is an increasing awareness among divers that we owe it to the ocean to do our part to look after it.
David Attenborough said, “I wish the world was twice as big and half of it was still unexplored.” For many of us, this is true. The world is double its size and the parts that are waiting to be explored by us are under the water’s surface.
