SonoAlti G2 Unique In Audible Comparison

Bluetooth connection, 32 alarm sounds and syncs jumps to a Logbook, are just a few highlights of the SonoAlti G2 that shows off the unique design of the newest audible altimeter at ChutingStar.

Thanks to designer Casey Mongoven of Freefall Data Systems who integrated the Bluetooth connection, you can manage the SonoAlti G2 settings from an app on your phone. Any of 32 alarm sounds can be selected for an unlimited number of alarms for freefall or canopy flight, and then those alarms can be further adjusted by volume, pitch and tempo.

See this overview of the new SonoAlti G2 below, which is now available at ChutingStar at this link.

The SonoAlti G2 is one of 14 audible altimeters currently stocked and supported by ChutingStar.

By far the most popular audibles are those manufactured by Larsen & Brusgaard, which include the Solo II, Optima II, Quattro and Protrack II. L&B out of Denmark is well known for its quality altimeters and customer service.

Although most known and used as a visual altimeter, the Alti-2 Atlas II is the only dual-use altimeter in that it can be used as a visual or audible. It is the most expensive unit available at $429. But Alti-2 has recently added a line of audible-only altimeters, the Mercury Jade for $239 (freefall alarms only) and Mercury Crimson (freefall + canopy alarms) for $299.

The least expensive audible, at $143, comes from the UK: the AON2 Brilliant Pebbles. This audible connects to your computer, tablet or smartphone by App wirelessly, allowing you to set up to 20 different alarms.

Next up in price and features comes from Parasport Italia with the NeoXs 2. This audible has all the freefall and canopy flight audible basics and more.

And for those who want LED lights plus audible alarms, go no further than the new ColorAlti G2 from Freefall Data Systems. This unit includes all the features of the SonoAlti G2 plus an LED light system for your helmet for visually warning you of your preset altitudes.

Freefall Data Systems is also the only audible we carry that has a speaking alert version: SonoAlti 3V. Read more on that truly unique audible below, and see this comparison on all the Freefall Data Systems audibles.

And then for those that are dedicated wingsuit flyers or canopy pilots, the FlySight 2 GPS Audible by Bionic Avionics is the only audible to give realtime feedback on your glide ratio, horizontal speed and vertical speed.

So lets take a closer look at all of the features of the top rated skydiving audibles below.
