Best Altimeter Reviews

An altimeter is an instrument to measure altitude; the vertical distance between the altimeter and mean sea level. Please remember that altitude, elevation, and height are different.

Altimeters can come in a watch (altimeter watch). This model is appropriate to use for hiking, mountain climbing, etc. This watch can be also equipped with a GPS sensor for navigation purposes. Audible altimeters are used in skydiving as an altitude awareness tool. A mounted altimeter is appropriate for vehicles. The mounted model commonly comes with a barometer and inclinometer.

Many altimeters on the market are barometric altimeters that work based on atmospheric pressure. The more the altitude (higher places) increases, the thinner the air density, the lower the air pressure to be.

There is also a laser and GPS altimeter. Barometric pressure altimeters work best in places where GPS signal is hard to get.

If you are going to buy a new altimeter, perhaps, the following top 9 best altimeter reviews may be suitable for your need and helpful to check to save you time. We also suggest the one that is the best altimeter for all occasions.

A Little History of Altimeter

The very first man who invented the altimeter was Louis Paul Cailletet, a French physicist. His inspiration came from his father’s ironworks. Then, his high interest in aeronautics gave him the path to develop an altimeter to measure an airplane’s altitude.

Paul Kollsman, a German civil engineer, made such a drastic change for the aviation world by inventing the first accurate altimeter in 1928. It is also known as the “Kollsman Window.” It compared the air pressure to sea level pressure in the feet unit. The radio altimeter was then invented by Lloyd Espenschied, an electrical engineer who graduated from the Pratt Institute in 1924. This type works by monitoring the return time of transmitted radio waves after reflected by the ground to get the altitude information above the ground. The clear difference between radio altimeter and barometric is the radio type measures the altitude above the ground. In contrast, the barometric type measures it above sea level.

Things to Considering Buying Altimeter

1. Accuracy

In some crucial moments such as in outdoor activity, a misleading altitude reading can cause harm to you. Altitude can increase dehydration. If you are dehydrated in an unwanted place, your life is at risk. Therefore, you need an altimeter that gives an accurate measurement of the altitude.

Simply, if you are a skydiver or aircraft pilot or hiker, the accuracy of this instrument is very vital.

One simple and independent way you could do to verify your altimeter accuracy is by calibrating it yourself. Go to a known altitude place, then see what your altimeter shows. If it is matching, it’s accurate. You could calculate the error and consider it when taking readings on the other unknown places.

2. Measurement Range

The second specification you must keep in mind is the measurement range. It determines how high the place, mountain, or flight you can go to. If the location you are standing in is out of the measurement range, then your device may mislead you.

On an important or even dangerous event that might happen, you will likely be at a huge disadvantage. So, make sure the altimeter watch or another altimeter model you buy can cover the location altitude you will be at.

3. Construction Quality

In most cases, the use of an altimeter will be needed in extreme places or locations. The quality of altimeter construction is critical because it is related to durability and functionality.

4. Portability and Size

Nowadays, altimeter comes in various sizes and portability. The old ones had a larger dimension and mostly applied in the aviation world. The modern altimeter does not only present in a smaller size but also wider portability. It has even developed in the application form so you could use it right using your smartphones. In this case, you reduce the number of devices to carry.

5. Battery Life

Another vital thing you have to never forget to consider when concluding your choice is battery life, especially when you narrow your need to an altimeter watch model. Since you will carry it outdoor, the chance to replace the battery is almost impossible. Bringing the battery backup may be optionable but it’s better to have an altimeter watch that long last so that you are not disturbed on the way.

6. Features

Altimeter is often available in a bundle with another barometer and compass. These three things unite into one instrument and they can be called ABC type.

But it’s not weird that modern altimeters provide more features than the simple ABC type such as GPS, thermometer, maps, weather, and even social media upload.

Some altimeters come in a watch. For skydiving, having an audible altimeter is really critical for safety. The heart rate reading feature may also come with it; it is a pretty impressive feature for health monitoring purposes.


An altimeter is used to measure the distance from sea level to the altimeter. Knowing your altitude is important for safety purposes. Therefore, it’s not weird to carry this tool when doing extreme outdoor activities.

The above are our findings of the best altimeter options on the market that you can pick. If you are still confused, our advice is to use the altimeter watch model. This model is easy to carry since it’s wrapped around our wrist. The watch model is also considered suitable for most uses.
