Top 12 Marine Compass Reviews

1. TurnOnSport Boat Compass

Marine navigation has never been more accurate with TurnOnSport Boat Compass. Accuracy has always been one of the most critical issues with marine compasses, but TurnOnSport’s compensators easily settle this concern.

One of the highlights of TurnOnSport is its East-West and North-South compensators that minimize external influences on the marine compass. This leads to a more precise direction, making it one of the most reliable and in-demand compass brands in the market today.

The compensators aren’t my only favorite thing about TurnOnSport. I also like that it’s dependable day in and day out. At night, its incandescent light makes the device visible and readable. There is nothing to worry about when the dark sets in.

And if you’re concerned about the rugged marine conditions, this brand is definitely up for the tough times. The compass’s made from ABS plastic, which is waterproof and corrosion-resistant.

Despite its hefty size, the device remains lightweight. Installing it yourself will be a breeze. The compass comes with two EVA stickers and two screws, so mounting is never a challenge. Just look for the sweet spot, stick it up or screw it and you’re done.

You also do not have to worry about exposing the compass to too much sunlight as it has a movable cover for shade. Whether it’s a big boat or a kayak, TurnOnSport is your dependable marine compass.

One downside is the size may be a bit bulky.
  • Reliable East-West, North-South compensators for accurate direction.
  • With incandescent lights for nighttime viewing.
  • Lightweight, waterproof and corrosion-resistant.
  • Easy setup using freebie stickers or screws.
  • Has sun cover to avoid too much sun exposure.

2. Ritchie Navigation Compass Surface Mount

Reliable utility and superior accuracy are what Ritchie Navigation Explorer Compasses are known for. With over a century of experience in the marine industry, Ritchie Navigation products remain top producers of navigational compasses for commercial and recreational boats. So, what’s up with their Explorer compasses? Find out in this review.

One of my pet peeves with compasses is how unreliable they can be. But this 2.75″ surface mount compass has what it takes to be considered a trustworthy product. I love that the makers reinforced the device with a triple cup sapphire jewel and a toughened steel pivot where every micrometer matches to a tee.

As a result, the device operates quite smoothly and locks on rather quickly even when subjected to extremes.

To be more specific about it, this device sports High Gauss Magnets customized for different compass specifications. These magnets seek and lock to magnetic north, so you know you are always right on track.

Another must-have utility for any boat compass is compensators. You can tick that box off as this compass has those. It has solid, built-in, non-interactive magnets that act as compensators for correction and accuracy. Moreover, you will get to enjoy its nighttime internal green illumination using a 12V power light.

However, over time, the adjustment rod may start to rattle.
  • Accuracy guaranteed with its triple cup sapphire and robust steel pivot.
  • Uses High Gauss Magnets that point to magnetic north.
  • Its solid compensators reliably correct deviations.
  • Green light illumination for nighttime navigation.

Tired of an unreliable compass? Odowalker Electronic Marine Digital Compass is one of the few top-of-the-line brands that hold on to promised accuracy and aesthetics. It is highly functional and straightforward, giving you spot-on directions without a lot of fuss.

If you’re a sailing enthusiast as I am, then you’ll definitely find this device to be quite a dependable buddy at sea. The device is sturdy and is made for tough times using high-quality ABS material.

Nighttime sailing can also be extra challenging for sailors, as poor lighting impairs much-needed visibility onboard. So I like that Odowalker had its compass built with an incandescent bulb light to illuminate the compass. This makes the device readable even at night.

Another thing I like about Odo Walker is how easily you can adjust the declination sheet. Thanks to its adjustable brackets, managing the compass’s position relative to the viewer’s angle can be done swiftly. I did not have to stay in one spot to get a good view of the compass.

Moreover, this compass is not just for marine use. It’s also best suited for cars, trucks, and other land-based automobiles. Odo Walker is truly one of the most flexible compass devices you can get out there. The device is available in black and white colors with a neat-looking design.

  • Manage compass’s position easily using its adjustable declination sheet.

The right marine compass for me comes from the reliable company DETUCK. I love this dash mount marine compass because I can use it night and day thanks to its night lighting feature and red indicator line.

The magnetic declination easily identifies both east-west and north-south directions, so I never get lost in the middle of the ocean as it improves the compass’s accuracy. I have come across several compasses that come with this feature, but not all of them are as easy to adjust as this one.

For a light traveler like me, I always choose to bring lightweight objects. I am glad that this compact compass only weighs 2.7 ounces. It is light on both my hands and in my pocket. Plus, it is also easy to mount as it comes with double-sided tape and screws that you attach to the dashboard.

There is almost no issue with this compass, aside from the tiring configuration that you have to do from time to time. To steer clear of going in the wrong direction, you must ensure that the compass’s horizontal level is adjusted and rotates freely.

It gives me a quick heading lock-on so I can have a more precise direction anywhere I go. You know you are in good hands with RITCHIE because they offer a 5-year warranty on all items.

It may seem like a perfect compass, but the thing is that this compass needs a little calibration to operate smoothly. Not to fret though, the calibration is as easy as one, two, and three. It would not even take up too much of your time.

Buyer’s Guide


We all want to make our buy worthy. That’s why everyone should be equipped with some info regarding marine compasses. So, what are the two important things that you must keep in mind? Well, first is the mounting method.

If you choose the correct mounting method before buying your compass, you will notice how it makes all the difference. There are different mounting methods, but I will just introduce the four common ones and exclude less common types like the overhead marine compass. They are the bracket mount, flush-mount, surface mount, and binnacle mount.

In a bracket mount, the compass usually rests in a bracket. You can mount this type on helms or decks. It is also easy to do, and you can have the right angle right away, which is why it is loved by many compass users.

Next is the flush mount. In this type, the compass lies inside the dashboard. It comes with a challenging assembly, but I can guarantee that the quality and visuals that this mounting type offers are out of this world.

The surface mount is where the compass sits on top of the dashboard. Just like a bracket mount, it is also easy to install. If you opt for a decent-looking installation, then you should go for this one.

Lastly, the binnacle mount. Just like the name says, a binnacle-mounted compass comes with its own case. It also looks decent and classy, but this mounting type may be bulky and takes up a lot of space. It also needs a lot of work, just like a flush mount.

After knowing the mounting types, I know that you already have your favorite in mind. It is time to go to the next thing that you should consider – the size. You would not want a bulky compass attached to a tiny helm. Besides that, the right size allows you to read the direction quickly and easily, even after installation.

Remember that smaller to mid-sized ones can range from 4 to 5 inches wide. Small sailboats, usually under 20 ft., are better suited with a small surface-mounted compass.

Do Marine Compasses Come with Mounting Brackets


A bracket-mount compass usually comes with a mounting bracket. Some compasses do not come with a bracket mount, but there are times when you can convert one type of mount to another — for example, using a bracket to convert a flush mount to a bracket mount.

If you do not want to have a bracket mount, you can opt for Ritchie Explorer, Voyager, or Navigation Globemaster models.

How to Adjust My Marine Compass

Marine compass adjustments can be a piece of cake or a headache. But the general rule is to head zero degrees using the compass while disregarding the heading. After that, you should turn exactly 180 degrees and adjust the compensator. This will take out half the overshoot or undershoot. You can then repeat the steps on 90 to adjust the fore compensator.

How Do You Make Sure the Compass is Running True to Its Lines

To know if your compass is running accurately, you should observe these things. Put the compass on a non-magnetic flat surface.

Afterward, you should turn it in a clockwise and counter-clockwise direction. If the compass is accurate, the needle should act like a match stick that floats in the middle of a basin of liquid that you twist.


Calibrating a compass is one of the most challenging parts for me. I know that you can eventually get used to it, but the quality of a compass also plays a part. Choose a compass that delivers accurate direction and does not require constant calibration or tapping. It will save your time a lot.

Choose the best marine compass that comes with your preferred mounting type. By doing so, you can install something that you can actually handle. If you are a starter, choosing a bracket or surface mount is a good idea.

Besides, If you are care more about cabin products for boat such as boat seats or boat carpets, you also can search them on categories on the top of the article.
