Walking into the dive computer section at 72 Aquatics can feel a bit like walking into an Apple Store. There are sleek screens, color displays, and a lot of tech specs. But before you decide on a brand or a color, you have to decide on the form factor.
There are two main schools of thought in diving: the Console diver and the Wrist diver. Neither is “better,” but one is likely much better for you. Here is how to decide.
The Console Computer: The “All-in-One” Workhorse
A console computer replaces your analog pressure gauge. It lives at the end of a high-pressure hose connected to your regulator.
The Pros:
-
Hard to Lose: This is the biggest selling point. Because it is physically screwed into your regulator, you can’t leave it in your hotel room or drop it off the side of the boat unless you throw your whole regulator in.
-
Big Screens: Consoles generally have larger, rectangular screens with large numbers, making them excellent for divers who want maximum readability.
-
Simplicity: You put your regulator on a tank, and you are done. There is nothing to strap to your arm, and you have your air pressure and depth data in one single place.
The Cons:
-
Bulkier for Travel: You can’t just throw it in your carry-on. It stays with your regulator bag.
-
The “Drag” Factor: If you don’t clip it off properly, consoles can drag across the reef.
-
Readability: To check your computer, you have to reach down, find the console, and bring it up. It requires a hand.
Best For: Divers who prioritize simplicity, large text, and who never want to worry about misplacing their computer.
The Wrist Computer: The Streamlined Traveler
Wrist computers are worn… well, on your wrist. They range from watch-sized units you can wear to dinner (like the Garmin Descent) to larger technical displays (like the Shearwater Perdix).
The Pros:
-
Situational Awareness: This is the biggest safety advantage. Your data is “always on.” You can check your depth or time with a subtle glance without stopping what you are doing.
-
Streamlined Profile: You are more hydrodynamic. There are no hoses to drag.
-
Travel Friendly: You can wear it on the plane! This protects your expensive investment from being tossed around in checked luggage.
-
Rental Ready: If you don’t own your own regulator yet, a wrist computer is the perfect first purchase. You can take it on any trip and use it with rental gear.
The Cons:
-
The “Whoops” Factor: It is easier to leave a wrist computer in a rinse tank or a hotel room.
-
Strap Management: Putting a computer on over a thick wetsuit or dry suit can be fiddly if you don’t have a good bungee mount or strap.
The Game Changer: Wireless Air Integration
Historically, the downside of a wrist computer was that you still needed a hose and a gauge to tell you how much air you had. Not anymore.
Most modern high-end wrist computers now offer Wireless Air Integration. You screw a small transmitter (about the size of a thumb) into your regulator’s first stage. It beams your tank pressure directly to your wrist computer.
This offers the best of both worlds:
-
Streamlined: You can completely remove the high-pressure hose and analog gauge, leaving you with zero drag.
-
Smart Data: Your computer can now calculate exactly how many minutes of air you have left at your current breathing rate (Air Time Remaining), which is a huge safety feature.
Which Should You Choose?
-
The “Minimalist” Traveler: Go for a Wrist Computer with Air Integration. It’s the lightest, cleanest setup for travel.
-
The “Set It and Forget It” Diver: Go for a Console. You’ll never have to worry about forgetting it, and the large screen is a joy to read.
-
The New Diver on a Budget: Start with a standard Wrist Computer (non-air integrated). It allows you to rent regulators anywhere in the world while keeping your safety data personal.
Still undecided? The best way to choose is to feel them. Come into 72 Aquatics and strap a shearwater to your wrist, hold a console in your hand, and see which screen makes sense to your eyes. We’ll help you find the perfect fit for your next adventure.
