At AON2, we connect people to their passion for sports.

We are a startup company that designs and manufactures wearable altimeters for skydiving and other aerial sports. AON2 was founded in Bristol by a team of aeronautical engineers and passionate skydivers, and it is our mission to increase the enjoyment and safety of our sport by increasing altitude awareness.

“Exceptional service from a UK company, fully designed by an aerospace technologist who actually takes part in the sport and has the skydivers as his number 1 customer. I am fully satisfied with his pebble product as it does exactly as it says on the packet. It has been jumped with many times.”
