Best Marine Compasses Reviewed

Venturing onto the water can be a dangerous undertaking. Regardless of other hazards out there – one of the most common mishaps for many is getting lost. On the open ocean, it’s very easy to lose one’s bearings, but sea-going fishermen aren’t the only ones that have trouble travelling the right path. Inshore waters and lakes are just as prone to thick fog and unfamiliar stretches of shoreline where the boater can’t tell which way is the right way to go.

Marine electronics have made a huge difference to how we get around on the water; and GPS navigation is almost standard these days. But for anyone serious about fishing and boating offshore and in unpredictable environments; the GPS commonly works in tandem with a quality compass.

Without the requirement for power or satellite access to find its bearings; a compass works regardless of the conditions. There is no lag between location input and display; making it much easier to plot a course via compass than watch a GPS screen. Switched-on anglers and boaters incorporate a quality compass into their boat’s navigational system.

Best Brands

There are several high quality compass manufacturers out there, but simple proof comes from the most popular public choices – and that choice is Ritchie. This company has been manufacturing compasses since 1850 and is highly regarded for its choice of quality products available for a variety of specific marine uses.

Ritchie is heavily featured in this list, as it should be. Providing options from economical to high-end expensive; there’s a compass to suit every budget; and every one is fully repairable and backed by a 5 year warranty. It’s hard to argue with that!

Several other compass brands also feature in the list for their provision of task-specific models, suited to particular uses or notable in their economy and performance.

Things to Consider when Buying a Compass

Choosing a compass for the fishing boat has to take a few things into consideration. Where will the compass be fitted, and where will the operator be viewing it from? Is the craft a large or small boat, or a kayak or canoe? Will the compass need extra features to perform in the conditions?

Where will it be mounted?

There are several compass designs, suited to specific mounting situations. This will vary depending on the craft they’re to be fitted to; and the specific uses required of the compass.

Bracket mount compasses fit into an adjustable bracket that is fastened to the craft. Brackets are commonly reversible and highly adjustable; making them well suited to all kinds of mounting situations.

Flush/surface mount compasses fit flush to the dash, bulkhead or deck (depending on the craft).

Dash mount compasses fit into sockets cut into the dash of boat consoles, so that they fit flush and match with other dials such as fuel gauges. These compasses are unobtrusive and well protected from knocks and scratches. Visibility is often aided by internal powered lighting; though they can easily be seen in ambient light.

Bulkhead mount compasses are usually quite large and are designed to fit into the bulkhead of boats – particularly sailing vessels. They can be adjusted through a range of degrees between vertical and halfway to horizontal, to accommodate the sloping surfaces of bulkheads.

Where will you be reading it from?

Another consideration, related to where the compass is to be mounted, is where you will be viewing it from. Several compass dial types are available which are suited to reading from particular angles.

Direct-read dials are common in bracket mount compasses and feature a domed dial with the bearings scribed on it. These dials are easiest to read when looking at the compass from a horizontal plane as the bearings are most prominent and magnified.

Flat-card dials are found in flush mounted compasses designed to be looked at from above. The flat dial is barely visible from a horizontal angle.

Combi-dial dials are a mix of both o the other two. A sloped area shows bearings from a horizontal plane, then the sloped dial changes angle to a flat top which also shows the bearings, being visible from above.

Does it need any extra features?

There are only so many features that can be tucked into a small compass – and it’s a god rule that less-is-more. After all, you want to spend your money on reliable navigation – not bells and whistles!

Many marine compasses are manufactured with inbuilt lighting, commonly powered by the 12V battery in the boat. This makes them easily useable in low-light and at night; but it does require that the wiring be hooked up – and that the boat have power. Don’t worry – the rest of the compass will work regardless!

Some compasses are fitted with sunshields. These are a great idea to cut back on glare that can obscure the reading of the dial. Adjustable visors mean that the sun can be blocked no matter what angle it’s coming from.

Various attachment systems are available for compasses. For flush, dash and bulkhead mounts, a hole is usually required to be cut to fit the underside of the compass. Bracket mounts may come with adhesive pads for attachment. Other designs have quick-release options. It’s a good idea to choose a solid base attachment (screws are the most reliable where possible). A compass relies on having a solid attachment and correct alignment so that the user can most easily see the direction that they wish to travel in, and point the boat that way.

10 Best Marine Compasses

Criteria for Evaluation

Accuracy and Reliability

A compass that doesn’t point exactly where it’s supposed to 100% of the time is simply not good. There is no room for error in this regard.

The only compasses that have been included in this review are those that were shown to be reliable workers through public feedback on the product. If there was even a suggestion of poor performance, it was cut!

That’s not to count those that failed to correctly calibrate their compass. It’s important to do so for a few reasons. The Earth’s magnetic field varies in strength depending on where in the world you are – and quality compasses like Ritchie account for this in their manufacture and can be calibrated to the correct world zone at purchase. Additionally, depending on where the compass is mounted and its proximity to magnetic and metal objects, the compass can be ‘thrown off’. Therefore it’s important to make use of the calibration settings incorporated into these compasses to adjust it so that it reads correctly in its mounted position.

It’s great to see that superb accuracy and reliability is available at really affordable prices – that way everyone can access this vital piece of safety equipment.

Mount and Dial Type

Every boat and every user is different and no one size fits all. Therefore it’s important to cover a range of options that address the various ways that compasses can be incorporated into the craft. A selection was made of the best options available for the various mounting systems; and where possible the various dial types also.

It’s nice to see that there are specific designs for kayakers who may be venturing into open waters. You’d sure be glad of a compass if you were to be towed out to sea by a record fish!

Price

Price is always a consideration, and all effort was made to provide a range of quality products fit for all budgets. Navigation equipment is safety equipment at the end of the day and as such, shouldn’t be skimped on to save a couple of bucks. Thankfully, many options fit into easily affordable price ranges. Only the most specific compasses, suited to high performance racing and sailing, became restrictive due to price.

FAQs

How do I adjust my compass?

To start with, you’ll have to find a location that’s close enough to the operator so that they can easily see the compass; and that isn’t overly affected by surrounding objects (such as magnets, ferrous metals and electronics). Test potential locations to see whether deviation is an issue. Make sure to move things around (like the steering wheel, throttle etc.) in case their movement causes deviation; and switch electronics on and off. The manufacturer’s guidelines will specify what degree of deviation is able to be corrected by the compasses in-built compensators.

Once you’ve found a suitable location for the compass, the next thing is to align it with the boat. It’s extremely important to properly align your compass with the centre-line of the craft so that it points in the direction that the boat is travelling. Errors in alignment of the compass will be constant and will require the re-alignment of the compass.

Once you’ve done this, you can fasten the compass to the boat and make adjustments for deviation. Remember to use non-magnetic fasteners.

The best approach to adjusting the compass is to work in conjunction with a marine chart. Choose some points that you can align by eye that are within 10⁰ of North/South. Run your boat along this line and adjust the port/starboard adjustor on your compass accordingly so it reads the same as the chart (following manufacturer’s guidelines for adjustment).

Once the compass is running true to this line; test it again on an East/West bearing; and adjust the fore/aft adjustor until it’s reading correctly. Next, run the boat back down the North/South line (the opposite direction to your initial course). If the compass is off at this point, there is an error in mounting to the craft, and the compass must be re-aligned before completing the process again.

Can I mount my compass in my car?

Many people use marine compasses in their vehicles. They are handy for off-road activities and driving at night, where it’s easy to lose one’s bearings. Mounting a compass in a vehicle is much the same as mounting it in a boat – remembering that deviation from surrounding magnetic sources I likely to cause issues.

It can sometimes be difficult to find a good mounting position in a vehicle because of all the gadgetry close by. Take your time to test potential locations and manipulate sources of deviation so as to ensure that you don’t miss an interference that isn’t noticeable when the car isn’t running, for example. Test things like car stereos and speakers as these are known to affect compasses.

I paddle my kayak/canoe on closed waters, do I need a compass?

You may not need a compass on closed waters, depending on your navigation skill and the type of environment. River travel rarely requires the use of a compass as both banks are mostly visible and the flow of water provides a constant direction (downhill – which can be referred to on a map of the area).

On lakes, a compass can be handy when weather sets in or when travelling to areas where you aren’t familiar with the shoreline. It can be extremely difficult to find bays, creeks and even river mouths on highly convoluted and wooded shorelines as everything merges into a mass of trees and undulating ground. Using a compass in conjunction with a map of the area allows you to find visible landmarks and plot a course using them in conjunction with your compass, ensuring that you travel in the right direction and find your way through the wilderness.

The Final Choice

A good quality compass is vital safety equipment for serious boaters and offshore anglers. Without one of these installed, you run the risk of electronics failure while in unknown waters and the likelihood of not being able to define the correct course home.

The style of compass, while important in the ease of fitting to the craft, is nowhere near as important as quality and reliability of components. It’s worth spending the money on a compass that you can rely on when you need it most.
