If you are an avid driver, then you know that it is best to always be prepared for the unexpected. One way to prepare for the unexpected is by having an automotive altimeter in your vehicle. These devices help drivers see how high up they are, which can make avoiding sudden obstacles much easier when driving on mountainous terrain or near waterfalls. There are many different models of these tools available on the market; however, we have compiled a list of the 10 best automotive altimeters below!

5 Things To Consider Before Buying The Best Automotive Altimeters
1. You’ll see more hills than you thought possible.
Automotive altimeters work by measuring the air pressure inside of them where they’re mounted, plotting those measurements against their location on a map of the area you’re in, then using that location data to determine how tall a nearby hill or mountain is. Since they are measuring air pressure, altimeters only work when you do not scale side. They aren’t affected by changes in gravity-like GPS units are, which is why they use air pressure measurements rather than GPS-derived elevation data.
You’ll see hills everywhere. Drive down your favorite backroad? You’ll see little swells before your car crests over them at road level not very impressive! But every one of those swells will be visible on your dashboard. The more tightly packed the roads are around you, the better it gets old mining roads are just amazing with an altimeter since there are so many small swells in so many places you didn’t even think you could drive. Unless, of course, your favorite back road is a minefield then it might be best to leave the altimeter at home.
2. The more signal-blocking materials surrounding you, the better.
One reason that topographic maps are able to plot elevations in certain areas with such detail is that there are known lines of sight between reference points. Many countries use ground-based radio transmitters for this purpose since they have long wavelengths and can bend around hills without losing signal strength too much. If you live in an area where radio towers are sparse or nonexistent, though, having decent reception on your cell phone becomes very important since it’s one of the few ways to relay your location data and altimeter position data to mapping servers over the Internet. Now, if you don’t have cell phone service at all, then you’re going to be out of luck with an altimeter since it requires a connection to an online server in order for it to work. The more signal-blocking materials around you, the better off your map’s displayed elevations are going to be because using radio towers as reference points is useless if there are physical obstructions between them and your car. If you live in a canyon or something similar, or always find yourself on long drives where mountains block line of sight between transmitters, then having an altimeter is great because they use GPS coordinates rather than weak reference-point elevation measurements.
3. The more routes there are between you and the area’s reference points, the better.
In addition to the line of sight from transmitting towers, knowing how many ways can get from your car to those reference points is extremely important since altimeters only work if they’re able to detect a signal from at least three different transmitter locations. In most cases, this means that there must be a clear path from your car to three or more different cell phone towers—but not always! For example, it’s possible for a weak signal coming from somewhere on the other side of a mountain range to provide enough data for an altimeter without ever emerging above ground level itself. This inherently limits the accuracy of displayed elevations by introducing the potential for multipath error. If you’re in a canyon, or there are mountains all around you at all times, your map’s displayed elevations are going to be way off since it’ll have trouble finding three different tower locations to use as data points.
4. The more variability between their reference point elevations, the better.
The great thing about altimeters is that they don’t just directly measure how high an object is they also factor in atmospheric pressure in order to determine how much air is above the altimeter itself. This negates the difference between sea-level measurements and mountain-top measurements when using known landmarks as reference points, which means that each landmark will show up on your display screen at nearly the same height even though they’re at different elevations. Since altimeters also see a lot of use in low-pressure environments, such as airplanes and high-speed cars, this is a very good way to make your map display readings more accurate since it’ll ignore how much higher you must be from an object when there’s less atmosphere above you.
5. The more regularly they update their measurements, the better.
Altimeters work by measuring atmospheric pressure which is constantly in flux. In order for them to work properly, therefore, they have to regularly send out a signal that measures air pressure and then compare that data against previous measurements until it can determine whether or not its absolute altitude has changed within a certain amount of time after all if air pressure is constantly fluctuating, then the difference between your current air pressure and your previously recorded air pressure can be huge even though you’re only off by a small margin of actual elevation. For example: if an altimeter with a reference point roughly 100 feet above sea level lost signal for just one second, the resulting change in atmospheric pressure would make it measure its new altitude as being anywhere from 50 to 150 feet below sea level which is obviously quite wrong! All measurements made by altimeters are inherently approximate rather than exact because their data points aren’t static; they fluctuate all the time.
3 Advantages Of Automotive Altimeters
1. Displaying Accurate, Real-Time Elevation Information
If you tend to go up steep hills often, then owning an automotive altimeter is a real benefit because it allows you to quickly see how many feet you have climbed since starting your ascent. This provides drivers with a better idea of exactly how high they are driving, an essential element for safe driving in high elevation areas.
2. Provides Valuable Data About Speed and Distance Traveled
One great thing about owning an automotive altimeter is that it can provide you with important data when trying to keep track of your speed. Since many cars now have this technology built-in, all you have to do is register the exact location where your car was when the speedometer changed from mph to kph. It will then calculate how far you went before registering the change in speed, which can be helpful if you are trying to maintain a specific legal limit while driving yet don’t want to rely on only your odometer.
3. Helps Prevent Skidding by Providing Instant Feedback When Wheels Lose Contact with Ground
Another benefit to owning an automotive altimeter is that it can alert you when your car has lost contact with the ground, which can help prevent skidding after sudden halts or turns. It will immediately let you know if you are accelerating up a hill without actually touching the ground, thus ensuring that your wheels stay firmly on the tarmac at all times.
