Best Altimeter Reviews

An altimeter is an instrument used by people to measure altitude. The altitude information is vital and crucial for some occupations.

Using Altimeter for Hiking in Alpen

Jobs such as pilots (both aircraft and spacecraft) determines the flight procedures based on many parameters. One of them is altitude information, which plays a significant role. Other jobs such as mountaineers (hikers) and skydivers need the altitude information to find their position and location on the ground space or in the sky.

The classic and conventional altimeter is built by utilizing the comparison between the atmospheric pressure of present location height and the sea level pressure. By doing this procedure, the altitude can be measured. The more the altitude increases, the lower the air pressure decreases. It is caused by the thinner air density at higher places. This type is the most common altimeter used by people and is called a barometric altimeter.

As the technology expands and advances, the altimeter varies in some type based on the way the altitude is measured. They are radio altimeter, GNSS (GPS, Galileo) altimeter, laser altimeter, and altimeter app.

Regardless of your experience or occupation at the moment, whether you are a pilot, skydiver, or mountaineer, then, this article might be of some help to you as a guide or reference. Here, we try to cover some top altimeters and try to categorize them in each class. A buying guide is also included so that you are expected to get a broader insight when buying an altimeter.

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 get the measurement of 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 Consider Before Purchasing Altimeter

1. Accuracy

To get accurate altitude measurement must be the first thing you prioritize over others. It could ensure and increase your survivability in case you encounter the unexpected while skydiving, flying the aircraft, hiking, or even just running.

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 measurement range. Then no altitude could be measured. On an important or even dangerous event that might happen, you will likely be at a huge disadvantage. So, make sure the altimeter you buy can cover the location altitude you are going to 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 is not only presented in a smaller size but also wider portability. It has even been developed in the application form so we can use it inside our smartphones.

5. Features

It is such common knowledge that most altimeters do not come by themselves. It is often offered to the community in a bundle with barometer and compass (ABC type). Modern altimeters provide more features than the simple ABC type. Features such as GPS, thermometer, maps, weather, and even social media upload are available on modern altimeters. However, prioritizing your needs must come first aside from the rich features provided.

6. Cost of Ownership

In the end, everything revolves around money. Aligning the altimeter with the budget you can afford maybe the best way to get the altimeter you really need. Higher specifications and more features are going to require you to pay a decent amount of money. It is always about give and take. However, through this review article, we hope you could get some insights or even broader knowledge before you buy one.

Conclusion: What is the Best Overall Altimeter?

The altimeter is one of the linear measuring tools that measure the height of a certain position over a sea level. This is also one of the important tools to carry when you are doing extreme outdoor activity.

Finally, we have come all the way to the conclusion part of this article. You are always free to choose which altimeter type you are going to buy. Our pure and honest intention here is to give you as the readers a reference, guide, or simply an insight.

That being said, we highly recommend AltiLINQ 205-M by Sun Company as the best altimeter overall. Aside from its low and affordable price, it also has a decent measurement range, easy to mount, free of battery, and easy readability scale.
