Larsen & Brusgaard operates a policy of continuous development.
Therefore, we reserve the right to make changes and improvements to any of the
products described in this guide without prior notice.

WARNING!
FAILURE TO FOLLOW ALL WARNINGS, INSTRUCTIONS, AND REQUIRED PROCEDURES MAY
INCREASE THE RISK OF SERIOUS INJURY AND DEATH.
Always ensure your altimeter is adjusted to zero prior to jumping to account for any
changes in barometric pressure.
Altimeters may give erroneous readings if you are tumbling or the altimeter is in
a burble (wake), such as when sit flying or sky surfing. Chest mount altimeters are
more vulnerable to this problem. If you are in doubt about how this limitation af-
fects your skydiving, consult a licensed instructor.
DO NOT use this equipment unless you are on, or have passed an approved skydiving
course.
Use the ALTITRACK™ at your own risk.

Introduction
Analog Display with Digital Accuracy
At first glance, the ALTITRACK™ looks like many of the more common analog altimeters
used throughout the world... but look a little closer. The ALTITRACK™ is the only sport
altimeter with an analog face, but utilizes the most high tech and durable digital
components for accuracy that surpasses every other mechanical sport altimeter
currently available.
Imagine a visual altimeter that records your jump information from exit to landing,
has the ability to download jump information to a computer, has an ergonomic fit, is
both shock and water resistant, has upgradeable software... and most of all... is extremely
easy to use. You just found the answer you’ve been looking for...ALTITRACK™.
