Buyer’s Guide — Choosing Your Own Boat Speedometer

Best Boat Speedometer ReviewsHere’s all you need to know about buying the best boat speedometer.

Manual Speedometer

A manual boat speedometer measures the speed of your boat by using the water pressure that it encounters which changes accordingly as your boat moves faster or slower. Manual speedometers are the more traditional option so they’re falling out of popularity to be replaced by GPS speedometers. However, manual models still provide accurate readings nonetheless.

One common pitfall that could make this system not work properly is when there are loose or blocked components like with its pipes. With those problems, reading accuracy will be affected. But as long as you check it for maintenance now and then, you can be assured of getting accurate speed readings.

GPS Speedometer

Global positioning system or GPS speedometers, on the other hand, work using satellites up above our atmosphere. With the satellite readings, it constantly tracks your position and calculates how fast you’re moving based on the distance between your previous and current position and how fast you got there.

While this system may sound clunky and inefficient, it’s very fast and accurate. The satellite reading constantly gets updated at a very quick pace to provide you with your speed readings. GPS speedometers use digital displays as compared to manual speedometers more traditional displays. As a result, they can display other useful information such as a travel calculator or an odometer. Overall, when it comes to functionality, GPS speedometers have more to offer.

Since you’re now familiar with the differences between a manual and GPS speedometer, you might feel ready to make a decision. Before that, it would help to read the most common questions asked by consumers before their final purchase.

FAQs

Here are questions frequently asked about the best boat speedometers.

Q: What Does A Boat Speedometer Do?

A: Speedometers generally measure the instantaneous speed of a moving vehicle. They can do this quite accurately, and in different modes or displays as well. Most land vehicles, commonly cars, have speedometers on their dashboard. Boat speedometers essentially do the same for your marine vessel. Boat speedometers are, however, more complex in that they have to distinguish between the water speed and airspeed of your travel. It must also be able to tell its data in either nautical miles or simply miles.

Q: Is A GPS Speedometer Better Than A Manual Speedometer?

A: One of the things you have to consider when choosing between a manual and a GPS speedometer is whether or not it fits in your boat. Most boats already have a cut out in which the speedometer is meant to reside. More often than not, this is meant to be for manual speedometers. Manual speedometers, however, can only read how fast you are going across the water.

The problem with this reading is that your speed on water may not actually be the true speed you’re traveling at. You may be traveling against a tide, which makes your resultant speed less than your speed on the water. You may also be traveling with a tide, making you go faster in reality.

Although the effect is not extreme, the tide will still definitely have a resultant effect on your speed. A GPS speedometer gives you a reading of your true speed and can show several other pieces of data. You can simply try using both or you may choose between them.

Q: What Makes A Boat Speedometer Necessary?

A: One of the simple reasons that a speedometer for your boat is necessary is curiosity. Believe it or not, you will find yourself wondering during your boating adventure how fast you are going.

Another important reason is that there will be areas that impose a boat speed limit. You will need a speedometer to gauge that limit and continuously stay under that limit. Being aware of your boat speed will also help you learn to gauge distance and arrival time, and can even help you estimate how much energy or power you’re using at the moment.

Finally, we have some last pointers for you before you finally get set on purchasing a new speedometer.

Conclusion

Speedometers are very standard and essential for equipping and preparing a boat. There are two types to choose from: a digital type or a manual type. The digital speedometer has an easy display and can give a reading with a very high degree of accuracy. The manual type, on the other hand, has a simple method and can fit the usual pre-cut speedometer hole. It can read your water speed accurately, but may not account for the effect of the tides.

Boat speedometers can very well complement your other boat devices. These may be your GPS, your stereo, and chargers and such. All of these devices are available for your safety, security, convenience, and peace of mind at having your information at hand.

And when you no longer need that information because you’ve dropped anchor and decided to relax out at sea, that’s no problem. What’s important is that when you need it, that information will always be available to you. Even more importantly, the information should be accurate.

Both GPS and manual speedometers are useful and offer good enough degrees of accuracy. Although there is a lot to consider when choosing between them, it ultimately comes down to preference. When you go boating, you may not even need to always know your speed. If you are a very lax boater, then don’t worry too much about accuracy. Otherwise, splurging on a GPS and digital kit may end up being a good investment.

Through this guide, we hope that you have recognized which aspects to think about when choosing your speedometer. Although choosing between the manual and GPS speedometer may not matter much in the end, it is still important that you have at least one of them. Either one of them is quite convenient for installation and will still provide you that much-essential information.

So you may be going out for a relaxing fishing trip, or spending a day under the sun out with your boat. You may be taking some time to travel out from the coast and you are looking to reach somewhere. In any case, hardy and accurate speedometers are very handy.
