While most towns and other urban areas are well signposted and provide little difficulty for navigation, this may not always be the case in rural and less densely populated areas. When driving in such areas, you may find that you are more reliant on maps and compass points for navigation. While many cellphones have built-in maps and GPS apps, they are reliant on cell phone signals to work. So, how do you ensure correct navigation without street signs or a cell phone signal? The answer is to invest in a car compass. This ensures that you are always able to determine your direction of travel, regardless of any external signs. However, there are a wide variety of compasses on the market, many of which are less than suitable for use within a vehicle. So, how do you ensure that you purchase the best car compass for your needs? Our panel of automotive experts has compiled a list of the best car compasses to help point you in the right direction.

Best Car Compass Buying Guide & FAQ
One of the many difficulties related to finding the best compass for your car is the interaction between the compass and your vehicle. Metals and magnets can affect the workings of a compass and therefore, negatively affect its accuracy. An inaccurate compass can leave you completely lost, particularly if you happen to be driving off-road with no visible or at least recognizable landmarks. In this part of the buying guide, our panel of experts look at car compasses in more detail to help you make the right decision for your needs. We explore what you need to consider when buying a car compass, the benefits of a dashboard compass, and answer some of the most frequently asked questions about car compasses.
What to Consider When Buying a Car Compass
Suitability is one of the key considerations when purchasing a car compass for your vehicle; however, it is not the only consideration. Budget, fit, size, calibration, and ease of use are also as important.
It is important to set out how much you want to spend on a compass for your car. Compasses can range from a few dollars to a few hundred dollars, and while the very cheapest are not likely to be very durable or accurate over the longer term, more expensive does not always mean better.
Consider how much you want to spend against what you want to gain from the compass. If you want one with additional features such as a digital display, night lighting, and built-in compensators, then you are going to need to be willing to pay more than if you want a simple floating ball with a suction cup base.
Consider the quality of the materials that are used in the construction of the compass as well as its features. A more expensive compass that is made from durable materials, fits well to your dash without moving, and above all is shielded from the metal and magnetic components of your vehicle is more likely to be worth the higher price that you may need to pay.
There are numerous ways in which a car compass can be fitted to your vehicle. Suction cup fittings are one of the most common. This type of fitting allows your compass to be secured in place and moved when needed, either to be placed in a different vehicle or for storage when the vehicle is not in use. One downside of a suction cup fitting is that it can be affected by dirt, dust, and moisture; all of which can make the fitting less secure.
Adhesive strips are another common mounting aid. Once in place, these are difficult to remove, and new strips will be required in most cases if you remove the compass and try to reset it. Mounts can also be screwed to your dashboard; giving a more permanent attachment. Finally, there are flush fitting mounts that require you to cut a hole in your dash for the compass to sit into. The main benefit of this type of mount is the security of the fit. You can be assured that the compass isn’t going to move, slide, or otherwise fall off your dash. Such fittings also give a much lower profile to your compass, meaning that they are less obtrusive and take up less space. However, greater care needs to be taken with this type of fitting. Once you have cut the hole, repositioning the compass is difficult and will leave an unsightly hole in your dashboard.
Car compasses vary widely in size. If you purchase one that is too small, then you risk not being able to read it easily while you are driving. This could lead to a lack of attention being paid to the road in front of you. If it is too big for your dash, then it could fit poorly and get in the way. If the compass has a nightlight and is too big, you could find that this too interferes with your driving. Consider diameter and height measurements before making your final purchasing decision.
In order to work correctly, most car compasses need to be calibrated; some are easier than others. Take note of how to calibrate the compass, the possible interferences that you need to be aware of and ensure that the compass is designed to work in your hemisphere. Once calibrated, your compass should be accurate; however, it is worth looking for a compass that is free-floating or has built-in stabilizers. These features allow the compass to correct itself if it is jostled while going over uneven terrain or after taking several quick turns in direction. You do not want to have to wait while your compass keeps up with you.
- Ease of use
The purpose of having a car compass is to make navigation easier. If you have a compass that is hard to read, then this is not going to happen. Look for features that make the compass easy to use. This might include nighttime illumination, large compass point lettering, luminous or fluorescent lettering or numerals. Some compasses include a moveable sunshade to help reduce glare; others are capable of being mounted at any angle so that you can put them in the position that is most convenient for you.
Benefits of a Dashboard Compass
Having a compass in your vehicle allows you to navigate more precisely in areas without signage or a reliable GPS signal. However, traditional compasses are not designed or built to withstand the magnetic effects of your vehicle or to be used within metal surrounds, which can also affect a compass’ accuracy.
Dashboard compasses are specifically designed to be used with vehicles. They are built to withstand the rigors of driving as well as the issues of being placed within a moving metal enclosure. Compasses that are designed for your dashboard are also designed to stay put. They come with fittings that ensure that they attach firmly to your dashboard, reducing the risk of them sliding around or becoming a projectile should you need to stop suddenly.
Dashboard compasses are also designed to be easy to read while you are driving. This means that you do not need to take your hands off the wheel or your attention off the road to check your heading or position.
Best Car Compass FAQ:
Q: What is an auto compass?
A: An auto compass is a compass that is designed to work within your vehicle. It will comprise of the compass itself and a mount or other means of fixing the compass to the dashboard of your vehicle. It is important to choose a compass that can be fitted to your dash to stop it from moving around and to ensure accurate readings regardless of the terrain.
Q: How does a dashboard compass work?
A: How your dashboard compass works will depend on the type of compass you purchase. A magnetic compass is comprised of a lightweight, small magnet that pivots on a near frictionless point. One end of the needle is marked to indicate North; the area surrounding the compass will usually have numerical markings allowing to determine degrees away from North. These are not the best types of compass for your vehicle.
More commonly found in vehicles are floating compasses or ball compasses. In this type of compass, the ball or needle floats freely on a liquid, usually a light oil. The needle or ball then rotates to indicate North depending on magnetic attraction.
Digital compasses are more complex in their design. Such compasses use magnetic sensor technology that can sense differences in the earth’s magnetic field electronically. It can sense the difference between the earth’s magnetic field and other magnetic disturbances, such as that created by the electrical systems in your vehicle.
Q: How do I adjust a car compass?
A: The exact steps that you need to take to adjust your car compass will depend on the make and model of the compass. Refer to the manufacturer’s guide to ensure that you take the right steps for your specific compass. The principle behind the adjustments is the same with all compasses; to ensure that they read accurately within their given environment. If you have chosen a Ritchie car compass, then making these adjustments is simple.
- Find the two adjusting rods with slotted ends
- Place the compass in its intended position but do not fix in place.
- Select a course using two easily identifiable landmarks that are within 10 degrees of the North/South line
- Keep the marks lined up and move along the selected course.
- Move the compensators until the compass reads correctly.
- Reverse away from the marks, keeping the points lined up. If there is a discrepancy this time, move the compass itself until it is aligned.
- Repeat these steps until any discrepancy is removed and then fix the compass in place in its final position.
