Key takeaways
- An analog compass needs no battery and no calibration, which is why many instructors still want one on every diver, even if you also have a digital compass.
- Look for a large, clear lubber line, a side-reading window, a rotating bezel with index marks you can set in gloves, and tilt tolerance.
- Digital compasses on dive computers are convenient and can store headings, but they need calibration and battery power.
- Wrist mounting is best for active navigation. Console mounting keeps your wrist free but makes it harder to hold the compass level and in line with your body.
- Buy a compass with the right hemisphere balance for where you dive, or one that's marketed as global.
The quick answer
For most recreational divers, the best dive compass is a quality analog wrist compass, such as the Suunto SK-8 or the Scubapro FS-2, mounted on a bungee or strap. Add a dive computer with a built-in digital compass, such as the Suunto D5, Shearwater Peregrine TX or Garmin Descent Mk3i, if you want stored headings and one less device on your arm. Many divers carry both: the digital compass for convenience and the analog one as the backup that never needs a charge.

Best dive computers with digital compasses
A digital compass on a dive computer shows your heading on the same screen as depth and time. Most let you store a heading and show an arrow or deviation back to it, which makes out-and-back navigation easier. The trade-off is that they need calibration and battery power. For more on computer choices, read best wrist dive computers.
Suunto D5
$$$The D5 is Suunto's watch-size, color-screen computer with a built-in digital compass and wireless air integration support. It's a popular choice for divers who want navigation on a compact wrist unit. See our Suunto Nautic S vs D5 comparison if you're choosing between Suunto models.
Why we like it
- Compact watch-size design

Best console combo with a compass
If you prefer a console, the simplest route is a console that holds both your computer and an analog compass.
Oceanic Pro Plus 4.0 with Compass
$$$This is a hose-mounted, air-integrated console computer paired with an analog, liquid-filled compass in the same console boot, per the manufacturer's listing. The compass has a rotating bezel and side reading, and it keeps working even if the computer's battery runs flat. It suits divers who prefer a console and want gauge, computer and compass together. See wrist vs console dive computers for the trade-offs.
Why we like it
- Computer and analog compass in one console
- Compass needs no battery
- Replaceable computer battery

How to choose a dive compass
Analog, digital or both
Analog compasses are simple, reliable and never need a charge. Digital compasses are convenient and can store headings, but need calibration and a working battery. A common setup is a digital compass on your computer plus an analog compass on the other wrist or in a console. That way, a flat battery doesn't end your navigation.
Wrist or console
Wrist compasses are easier to hold level and in line with your body. That's the core of accurate compass navigation. Console compasses keep your wrist free and put all your instruments together, but you have to hold the console up in front of you, which can be awkward. Navigation instructors often prefer wrist mounting for courses.
Features that matter
- Lubber line: a clear line that shows your direction of travel. It should be easy to see in low visibility.
- Side-reading window: lets you read the heading while holding the compass level in front of you.
- Rotating bezel: with index marks you can set in gloves, and clicks that hold the setting.
- Tilt tolerance: a compass that still reads when not perfectly level helps in current.
- Luminous markings: helpful on night dives and in dark water. Charge them with a dive light.
- Hemisphere balance: compasses are balanced for magnetic dip in different regions. Buy the version for where you dive, or a globally balanced model if you travel widely.
Mistakes to avoid
- Mounting the compass on the same wrist as a big light or camera tray. Magnetic interference can throw off the reading.
- Buying a strap that won't fit over your cold-water suit. A bungee mount solves this.
- Relying only on a digital compass without calibrating it. Calibrate as your manual says, especially after travel.
- Not practicing. A compass is only useful if you can use it. Practice on land and in shallow water first.
- Ignoring natural navigation. Sand ripples, reef edges and the sun's direction are useful checks on your compass.
Gift idea for the holidays
A quality compass is a practical holiday gift for a diver who's just finished an open water course or is starting advanced training, since navigation is part of most advanced courses. Pair it with a bungee mount and a slate. See our best gifts for scuba divers for more ideas.

Frequently asked questions
What is the best dive compass?
For most divers, a quality analog wrist compass such as the Suunto SK-8 or Scubapro FS-2 is the best choice. It needs no battery and no calibration, and it's easy to hold level while navigating.
Do I need a dive compass if my computer has one?
Many instructors recommend carrying an analog compass as a backup, since a digital compass needs calibration and battery power. At a minimum, know how to navigate with natural references if your digital compass fails.
Is a wrist or console compass better?
Wrist compasses are easier to hold level and aligned with your body, which is why many navigation instructors prefer them. Console compasses keep all your instruments together but can be awkward for precise navigation.
What does hemisphere balancing mean on a compass?
Compass needles tilt with the earth's magnetic field, which varies by region. Compasses are balanced for specific zones so the needle stays level. Buy the version for where you dive, or a globally balanced model if you travel.
How do I calibrate a digital dive compass?
Follow your dive computer's manual. Most require you to rotate the computer in several directions or in a figure-eight pattern. Calibrate after travel, battery changes or when readings seem off.
Can a dive light affect my compass?
Yes. Magnets and metal in lights, cameras, steel tanks and some accessories can deflect a compass needle. Mount your compass away from them and check its reading against a known heading.
