In today’s market, when buying new skydiving gear, including audible altimeters, there are multiple options to choose from. Thus, it can become a hard decision because our skydiving friends are often suggesting their preferred piece of equipment. Although, advice is not a bad thing! However, sometimes what equipment is good for one person, may not be as optimal for another. And so, here we are going to give you a review of the top skydiving audible altimeters on the market today. Of course, the article includes the leading market producers, Larsen & Brusgaard. Though, there are some alternative options, which are really great audible altimeters to consider!

Audible altimeters

Firstly, lets go over a bit about audible altimeters, also referred to sometimes as ‘dytters’. In addition to visual altimeters, skydivers use audible altimeters as another method of keeping altitude awareness. Although, the use of an audible is not limited to only one function. Audibles also assist skydivers in other ways. Using preprogrammed altitude alerts, audible alarm reminders are used for break off, deployment and hard deck altitude. As well, audibles are used for canopy flight patterns. Especially assisting those who swoop in their more specific landing pattern sequences.

However, please note, your experience and eyesight should be your primary source for determining your landing pattern approaches.

Depending on where in the world you are skydiving, and at what dropzones, sometimes audibles may be mandatory. For AFF and tandem instructors, some associations/drop zones require the use of an audible. Also, if you are choosing to participate in free fly jumps, it may also be a DZ rule to wear an audible. However, even if not a rule at your drop zone, you should be jumping with an audible altimeter. Especially for any free flying, high speed jumping or big ways.

If you do not have an audible altimeter, forgot it at home, or ran out of batteries, be smart! Inform the people you are jumping with that you do not have an audible. Perhaps someone can lend you one. It is for the safety of the group that everyone is aware you do not have an audible. Anyone can get carried away in a really fun jump, and loose altitude awareness. Even if you do not think that it could be you, it very well could be!

The VOG audible altimeter quite a recent product on the market. Just as the name states, it is a SPEAKING audible, so not beep warnings. This is a very unique addition to the available audible altimeters on the market! After reading reviews, the voice speaking to you during your freefall does not seem to be distracting any jumpers who have used the device.

Although, while being designed by skydivers for skydivers, it does not have the same production capabilities as larger brands. So be patient in your order for your VOG Speaking Audible Altimeter. From my research, it seems the price is around 355 Euros or $400 USD. However, if incorrect, please let me know! Check out the included features of this futuristic audible:
