VoxAlti
Frequently Asked Questions
Q: How does VoxAlti compare to other audible altimeters that beep?
A: VoxAlti is a speaking audible, so it provides more constant altitude awareness than other types of audibles. VoxAlti does actually also has the ability to beep or produce sirens if one requires a more dramatic altitude indicator at a specific altitude.

Q: How do VoxAlti and its predecessor SonoAlti 4V differ?
A: VoxAlti is the loudest speaking audible FDS has ever produced. It combines the greatest strengths of three previous generations of FDS speaking audibles. It is waterproof to IP67 and logs jumps for syncing to FDS Logbook. That being said, it is slightly larger than the SonoAlti 4V.

Q: Can I create my own sounds for VoxAlti?
A: This is unfortunately not possible with VoxAlti.
A: This is unfortunately not possible with VoxAlti.
Q: I hear my audible going off and reading information on the ground. Why is this?
A: VoxAlti is a sensitive barometric pressure device. Driving in a car can be similar to the takeoff in an aircraft. If you do not want to hear the altimeter on the ground at all, it is recommended to turn off the pre-jump briefs in the FDS Altis app. You can also change the Ascent settings for the preset the altimeter is on: Do you have it from 0 to 30,000 ft? That is why it is reading at 0 feet; change the 0 to 100 feet or higher.

Q: Does VoxAlti come with any external speakers or earphones?
A: No, it only has a built-in speaker with no external ports.

Q: What is the advantage of this type of altimeter?
A: These devices are excellent for building general altitude awareness skills. Hearing a spoken altitude while simultaneously associating it with an altitude picture trains your eyes as well as your timing. Sometimes we are very unaware of how fast we are actually lose altitude on a skydive.

Q: Can I set the altimeter on the way to altitude?
A: Yes, one can select presets by holding down the top settings button in the aircraft. However, Freefall Data Systems always recommends doing any setting of altimeters on the ground before a skydive as to minimize distractions. Jumpers should be focused on safety and their jump in the aircraft.

Q: Is VoxAlti a logging device?
A: Yes! It works with our online logging system FDS Logbook.

Q: Does VoxAlti have GPS?
A: VoxAlti does not have GPS as that would reduce the battery life greatly and compromise dependability. Altitude measurements are based on barometric pressure changes.

Q: What helmets does it fit?
A: VoxAlti fits and can be heard well in most skydiving helmets that have an audible port or pocket.

Q: Is VoxAlti suitable for student use?
A: VoxAlti can be very useful in enhancing a student's altitude awareness and provide cues, but should only be used with the permission and under the supervision of a current instructor officially rated by a national parachuting organization such as the United States Parachute Association.

Q: Is VoxAlti waterproof?
A: Yes, VoxAlti is waterproof to IP67.
A: Yes, VoxAlti is waterproof to IP67.
Q: Is there a differentiation between ascent, canopy and freefall alarms?
A: Yes. VoxAlti differentiates between the three types of announcements and notifications: ascent, freefall, and canopy.
A: Yes. VoxAlti differentiates between the three types of announcements and notifications: ascent, freefall, and canopy.
Q: I notice some deviation between my wrist-mounted altimeter and my VoxAlti. Is this normal? Which is correct?
A: Yes. Because barometric altimeters are subject to wakes and burbles, their placement can affect their readings. Which is closer in accuracy will depend on the type of jump you are doing and how you have the altimeters mounted. In most cases, the deviation is not larger than a couple hundred feet at the very most. If the deviation is more, see whether the altimeters are at least synchronized during ascent in the plane and go from there. If they are synchronized in the plane or under canopy but not in freefall, then the placement of the altimeters is certainly affecting their synchronization in freefall. Altimeters placed in a wake will read higher than those in clean air. So if you are, for example, sit-flying or doing a tandem, it isn't an unlikely possibility that your altimeter is being subjected to a significant burble.

Q: What happens if the altimeter is reading an altitude or something else and I pass through the next announcement it should read?
A: The previous reading will be cut off, with altitude always being the first thing read if it is selected to be read.
