2020 Digital Altimeter Features Comparison

Digital skydiving altimeters have continued to be improved upon the past few years, but the recent release of the Dekunu One SmartAlti  and AON2 X2 has really shaken up the offerings for skydivers.

One by Dekunu is the first sport skydiving specific digital altimeter featuring GPS with 3D location tracking. After jump feedback includes jump-path mapping, G-force, swoop and landing zone analysis, which is all synced to the cloud to view, analyze and share.

So far, VISO II+ has stood strong and continues to be the best selling digital altimeter, but that doesn't mean it's the best choice specifically for you. Read on for a comparison of features to make that choice for yourself.

Skydivers in the U.S. essentially have 7 digital altimeters to choose from. So what are the features of each that would make you choose one over the other?

For starters, the digital altimeters currently available include:

What all of these altimeters have in common is a visual digital display that can be worn on the hand, wrist or mudflap in a variety of available mounts. All of these altimeters have buttons that allow access to a screen menu and generally have the same size of numbers on the visual display, which can be set to show feet or meters.

After that ... well ... each is quite a bit different depending on which altimeter you choose. Below you can visually see the size differences with the 4 of the altimeters, stacked from top to bottom: the AloXs, VISO II+, Atlas and ARES II.

The Atlas can be used as an audible, but the X2, One, AltiX, AloXs, VISO II+ and ARES II are visual altimeters only. The VISO II+, ARES II, AltiX and AloXs use replaceable batteries, but the Atlas, X2 and One are rechargeable through a USB cable.

The X2, VISO II+, ARES II, AloXs, AltiX and Atlas all come with at least one basic hand mount. These all have several additional mounting options separately available. Dekunu's One is available without any mounts, but most skydivers add the Elastic Wrist Mount or Mudflap Mount to their order.

All but the AltiX have a night jump backlight, or the screen data is visible at night.

Of the currently available altimeters, the AltiX is the least expensive at $199 and the One and X2 are most expensive at $400+. The physical size of the One and X2 are the largest with the AloXs being the smallest and the VISO II + and Atlas right inbetween. The AloXs, One and VISO II+ have plastic cases, while the ARES II, AltiX and Atlas have aluminum cases. The AltiX is the only digital altimeter with a traditional round shape.

The N3 and the Atlas are the same altimeter, just with a different case and charging port. The Neptune (since discontinued) was the original altimeter in this line manufactured by Alti-2 in the USA.

The ARES II is basically a VISO II+ in a metal case with additional features, which all started as the VISO for Denmark manufacturer L&B.

The AloXs has similar features to the previous Altitron altimeter from Parasport, but is now slimmed down with updated software. The AltiX is the most basic of all the digital altimeters focusing on displaying altitude, but also gives you info on your last jump and includes a simulation mode for ground training students.

The Dekunu One and AON2 X2 are the only current altimeters with GPS, allowing you map and you to analyze your entire jump and landing.

Here are some general specs of each that you can use to compare which altimeter is best for you.
