Sport parachuting is a hazardous activity that can result in injury or death. An altimeter is a mechanical device and may
malfunction, even when properly designed, built, assembled, maintained and used. Do not rely upon an altimeter for your
safety. Your altimeter must only be considered as an aid when checking your altitude.
“The needle can stick during both ascent and descent – a visual cross reference with the ground should be used in
combination with the altimeter”: USPA Skydivers Information Manual 8-5.03.C.2.
