Best Scuba Dive Compasses Reviews
Many dive computers also have a compass installed but it is still worth getting a separate (analog) dive compass for situations where you might be disorientated. Here are 10 of the best dive compasses that will help you navigate the beautiful underwater world.
1. Easiest to Read: XS Scuba Retractable Supertilt

Dive Compass Buying Guide
Having an analog compass as part of your dive gear is a smart idea for any diver as they tend to be more accurate and are more reliable than a digital compass in your dive computer.
But how do you decide which product is the most suitable for you? Here is a quick overview of what you need to know before buying one.
The Tilt of a Dive Compass
When you were in school, you were probably taught that a compass should lie perfectly horizontal for the best reading but how would you do this while you are floating in the water? That is where the tilt range comes in and it is a vital aspect of good quality dive compass.
Always check the product description for how much tilt it can handle. You want to make sure that you can get an accurate enough reading no matter your angle and position in the water or the underwater conditions are.
Visibility
There are two aspects of visibility that you need to check, the markings and the luminosity. Since you are likely to dive to a depth where you will have low light conditions, you need a design that is still visible when you have limited natural light in the water.
The best dive compasses have large markings and numbers as well as the other features that you will want. Look for big and bold degree bearing indicators in the color white which gives the greatest contrast against the standard black background. This goes for both the bezel and the interior. However, the interior has the added benefit of being luminescent, in most cases.
A luminescent face means that it is reflective or lights up, even in low light conditions. Different brands have different methods for providing a luminescent face but the Oceanglo used in Oceanic products is one of the more advanced examples.
Certain designs also make the numbers and markings luminescent which might be a good choice for night divers. Also, remember that the further down you go the more likely you are to become disorientated and the more difficult it is to get a good reading. So, more advanced divers that reach deeper depths should opt for a larger clearer design.
Size of a Scuba Diving Compass
Closely related to visibility is the size. How big this piece of dive equipment should depend on how well you can see, what size you are comfortable with for movement while diving and its position. Divers with lesser vision might prefer a larger face and bezel with bigger markings and numbers. This is also useful for night time divers.
Your own body type also influences the best size. For example, if you have a smaller wrist you do not want to make yourself more clunky by wearing a wrist-mounted dive compass that is too big for you.
Finally, think about where you want to store it while you are underwater i.e. on your wrist, as an add-on on your console or clipped on to an HP hose or your BCD?
Those that are clipped on your BCD or HP hose tend to be smaller because you want to remain as sleek as possible. In this case, a retractable model is ideal because you can bring it closer to your face.
Dive Compass Location
Make sure that you get a scuba diving compass that is calibrated for the hemisphere where you will be diving because there is a difference. The newest versions are able to cover a larger area of the world which is why you are most likely given the straightforward option that is intended for either the northern hemisphere or southern hemisphere.
Frequently Asked Questions:
Do I need a dive compass?
You really only need a dive compass if you are planning your own dives with a buddy, at which time they are an essential piece of scuba diving gear. If you are a recreational diver and normally dive with a divemaster then there is no real need for compasses.
However, if you feel safer and calmer with a compass, for the price they cost it is well worth the investment.
What is tilt tolerance on a diving compass?
The tilt tolerance on diving compasses is the degree to which you can tilt the compass before the needle gets stuck. So the higher the tilt tolerance of a compass the better it is, especially if you are reasonably new to diving as your movement in the water could cause the needle jamming to become a problem during use.
Which is best analog or digital dive compass?
Analog vs digital dive compasses, which is best. Although most dive computers have a digital compass included a lot of experienced divers still like to have the older technology of an analog compass with them for ease of use and for peace of mind. The digital compass is good but can tend to be not quite as accurate as an analog version.
