GPS Boat Speedometer Buying Guide: How It Works
The majority of boat speedometers will use the air pressure along with the water in order to create a reading. This happens by pushing a pitot tube through the keel of the boat.
Each time the boat moves, it pushes the water into the tube, after which the air gets compressed in a pitot. As the speed of the boat goes up, the air pressure also increases – which in turn gives you your speed reading.
When you are using a GPS speedometer, it calculates how fast you are able to go from one point to another. Because of this, a GPS speedometer is generally the more accurate choice while being the easiest to install.
Different Types of Speedometers to Consider
When you are looking to buy a speedometer, there are generally two options that you may go for: the manual and the GPS speedometer. Most people prefer the efficiency of the GPS speedometer, but there are also those that still enjoy the classic vibe given by the manual options. Depending on your preferences, you may also choose either one of them.
As we have previously mentioned, a GPS speedometer shows you your speed by calculating exactly how much it takes until you get from point A to point B on the water. This is generally done with the speedometer connecting with a variety of satellites in the attempt to keep track of your location. As such, they tend to have good accuracy, since they are not influenced by the currents of the water.
By nature, GPS speedometer has a quick refresh rate. The average rate is generally 0.25 seconds – but sometimes, it can also be faster. Moreover, since you do not have to wire then through the whole keel, they are also much easier to install.
Bear in mind that since they connect with satellites, every now and again – namely, when the weather is bad – they may lose signal due to the interference of the weather. They also tend to be more expensive, but all things considered, they are still seen as a worthwhile purchase.
While this type of speedometer may not have the accuracy of a GPS model, it is still quite precise. For example, if you are going over calm waters, the readings that you get on both units will be very precise and similar. However, the results tend to be slightly inaccurate when changes in the water currents occur.
Since it works by recording the pressure in the air, a manual speedometer will also have a much slower refresh rate in comparison to the GPS models. They also tend to be slightly more difficult to install. On the plus side, they are quite cheap when put in comparison, and they also look classy once you finished installing them.
Features to Consider When Buying a GPS Boat Speedometer
Whether you’re buying a GPS boat speedometer, a portable marine fuel tank or any other boat accessory, there are certain factors that you might want to keep in mind. When it comes to GPS speedometers, these are:
Does your boat speedometer use an imperial unit system or the metric kind? An old version of GPS boat speedometers may use just one of the two, but most modern options will allow you to dial for both of them. Considering your preferences, you may change the settings to suit you – no matter where you’re sailing in the world.
Ease of Installation
By nature, GPS boat speedometers are very easy to install. In most cases, if it’s not your average plug-in system, all you have to do is to create a hole in the instrument panel of the boat and connect the speedometer’s wires into the power source. Each speedometer may have different installation methods, so make sure that you check with other people that have used the product. In most cases, reviews are your best friends here.
GPS boat speedometers were, by design, created to be accurate. However, like every piece of technology, they are still prone to error – and every speedometer will have an error percentage behind every reading that it gives.
Generally, the manufacturer will give you straight away that error percentage so that you know exactly what to expect. You have the marine GPS Chartplotter that you can rely on, but you also need a good speedometer. For good accuracy, look for the models that have an error rate or 1-2%.
You might find it convenient to have all those fancy controls on your boat equipment, all of which allow you to show off to your friends when you are on the waters. Still, you don’t want to bend over backward in order to find your way around the navigation system. It should be very easy for you to use the system and read it. If the digital design is complicated, then you will just be awkwardly staring at the display, not knowing exactly what to do in case of a directional change.
A good GPS speedometer should come with a good display that is easy to read, at least from a distance of 1.5 meters. Before making the purchase and checking the size of the font, you should also see whether it has a backlit display or not. This way, your vision will not be damaged when the lighting environment is low.
Water and Dust Resistance
Every boat speedometer should have great dust and water-repellant properties. It should be able to withstand quite a number of conditions, including fog, heavy rain, and a variety of other difficult weather conditions. For example, the ideal waterproof rating of such a device would be IP67, meaning that you may immerse it in water up to a full 30 minutes, all the way down to 1.5 meters, without the unit suffering from any damage. Look for products that have around an IP65-IP67 range, since they tend to have great dust and water resistance.
How easy is it for you to read the control panel on your boat speedometer of choice? In most cases, a modern speedometer will have an LED display along with a control button set. Generally speaking, to improve usability, these units will feature the smallest number of buttons possible (three on average). Plus, they are generally placed on a large surface so that you may easily reach them without damaging your focus.
Finding a good GPS boat speedometer does not have to be a difficult task. Granted, it might take some research until you can find the perfect type or brand – but by informing yourself properly, you should be able to easily swim through the galore of types, features, and aspects to consider.
Hopefully, our guide managed to push you in the right direction and helped you make the best choice. Now, all that’s left for you is to take your boat up on open waters and put your GPS speedometer through the test.
