Larsen & Brusgaard Protrack II
Description

The ProTrack II is a digital audible altimeter and free-fall data recorder developed by Larsen & Brusgaard (L&B) for sport skydiving. It is a successor to the original ProTrack, combining an electronic altimeter with an integrated data-logging system.
The device uses barometric pressure to determine altitude and vertical speed. It provides separate audible alerts for climb, freefall, and canopy descent phases. These settings are fully configurable and allow the jumper to receive altitude cues through tones.
Internally, the ProTrack II logs altitude and speed data for each jump, including exit altitude, opening altitude, freefall time, and maximum speeds. The built-in memory can store multiple jump logs, which can be accessed through the onboard LCD screen or exported via micro-USB for digital review.
The ProTrack II is designed to fit most skydiving helmets using standard audible pockets.
FlySync Compatibility
You can use our Protrack 2 viewer online to quickly visualize your jump altitude and descent rate. You can also add them directly into your logbook.
