Air Integrated Dive computers have been on the market for decades, and for good reason. These devices provide several advantages over other dive computers, most notably that your AI computer will calculate your air consumption rates at differing depths, and provide an estimate of your air time remaining (how long you have left on a cylinder).
Here are several things to consider when shopping for an AI dive computer:
Hose-less or Console
If you are considering the purchase of an air integrated dive computer, your first decision will be whether you want a standard console type, or a hose-less model. They both have their charms.
1. Hose-less Computers
Hose-less AI computers have two components, the computer itself, and a transmitter. The computer is almost always wrist mounted, and the transmitter is screwed into a high pressure port of the regulator’s 1st stage. The major advantage of this type of computer is that you do not need to detach your computer from your scuba unit at the end of the dive. Also, this type of computer eliminates the high pressure hose which reduces your chance of entanglement. It also makes your regulator set smaller, which makes for easier packing. This is especially important for minimalist travelers who choose to fly with only a carry-on.
2. Console Computers
A console type AI computer is attached to a high pressure hose. Many models have a quick disconnect fitting. If you purchase one of these computers, make sure that there is no water on or in the high pressure hose fitting when you attach it to your HP hose. Also, it is important to be mindful of the condition of the O-rings in the quick disconnect fitting. The main advantage of a console AI computer over a wrist model is screen size. Larger screens are much easier to read. In addition, some manufacturers offer models that allow you to upload files such as fish identification photos, and maps of the dive site.
Not all Manufacturers use the same algorithm to calculate safe diving limits. Three common algorithm models are Haldane / Spencer, based on the PADI dive tables, Pelagic Z+ which is based on the RGBM, Reduced Gradient Bubble Model, and the Pelagic DSAT model. In general, the most conservative computers use the algorithms based on the RGBM model.
All the algorithms used by manufacturers are safe, but if you want more bottom time, then it is best to buy a computer that does not use the RGBM model. Some models use two separate algorithms so that you can choose either a liberal or conservative setting.
Some dive computers are notoriously conservative, which limits your dive time. If you are shopping for yourself and your dive buddy, it is a good idea to buy the same model for both people. This will help keep your dives times close to the same length.
Buying Online or Buying Local
There are a number of very good online scuba retailers. However, you may be able to make the same purchase from your local dive shop by asking for the MAP, or minimum advertised price. MAP is pronounced like the word “map.” If you find a price online that is lower than MAP, then more than likely, the retailer is either not an authorized dealer, or the computer has been discontinued and is being sold at a clearance price. Always buy a computer from an authorized dealer, and register your warranty with the manufacturer.
New or Used
If you buy a used dive computer, you have no way of knowing whether it has been maintained properly. Also, it is unlikely that the computer will come with a warranty. If you must buy used scuba gear, the standard pricing seems to be half of what a brand new unit costs. The price can be more if it is in very good condition, or less if in poor condition.
Frequently Asked Questions
Are hose-less computers safe?
Yes. In fact, depending on the type of diving you undertake, a hose-less computer can be safer than one attached to a high pressure hose. Having one fewer hose reduces the chance of entanglement and removes a potential point of failure.
What is the downside of using an air integrated dive computer?
The only downside is that you will need to replace the batteries on the transmitter from time to time.
Do air integrated computers have a higher failure rate than standard types?
No. However, if you’re using a hose-less computer you do need to be careful when lifting your scuba unit, because you do not want to lift it by the transmitter. This could damage the threads of your transmitter or regulator. It could also cause a tear in the O-ring. Also, you’ll want to keep an eye on the dive master, and make sure that the DM doesn’t make that mistake.
Do air integrated computers need any special maintenance?
Aside from installing fresh batteries periodically, the only other consideration is the O-ring. You should replace the O-ring either yearly, or in accordance with the manufacturer’s guidelines. If you are going to be using Nitrox, then do not lubricate the O-ring with silicone. Instead use an O2 safe lubricant such as Christo-Lube. Also, remember to use a Nitrox compatible O-ring.
Can my AI computer be serviced at my local dive shop?
The shop’s technician can change the batteries and O-rings, but a malfunctioning computer will need to be returned to the manufacturer for repair or replacement.
What kind of batteries do AI transmitters use?
Manufacturers use different types of batteries, and most have battery kits made for specific models. While you may be able to find batteries that will work in your computer at a local store, you should check with the manufacturer or dealer to make sure that using them will not void the computer’s warranty. In many cases, it is best to purchase the approved battery kit. They come with the correct size O-rings, and they are typically fairly inexpensive compared to the cost of your transmitter.
Can I use my wrist mounted, AI computer if the transmitter fails?
Yes. The computer will function as normal, except that it will not be able to keep track of your air consumption. If you do not have a submersible pressure gauge (SPG), then you will need to install one so that you can tell how much air is in your cylinder. It is best if your transmitter is installed on the left-hand side of the 1st stage. This makes it easier to replace it with an SPG. Do not install a high pressure hose on the right side of the 1st stage, because the hose can become entangled with the low pressure hoses for your 2nd stage regulators.
Every diver needs to take responsibility for their safety by choosing dive gear that is not only reliable, but also easy for them to use. This will ensure that they have the information that they need to be safe when in the water. Having a high-quality dive computer that is durable, able to provide plenty of information, and will sound an alarm in the event of an emergency is the best way for a diver to keep themself safe when they are under the water.
