2.4 Speed CYPRES
The Speed CYPRES can be recognized by the
red button with the white imprint „Speed“ on the
control unit.
It will activate the release unit when it detects a rate
of descent higher than approx. 102 mph (approx. 46
m/s) at an altitude below approx. 750 feet (approx.
225 meters) above ground level. Unlike the Expert
CYPRES, the Speed CYPRES ceases operation
below approx. 330 feet (approx. 100 meters) above
ground level.
The Speed CYPRES is designed to allow extreme
canopy piloting. The high activation speed plus the
feature that the unit ceases operation below 330 feet
are tailored for this discipline.
The Speed CYPRES is designed to activate reliably
in all „regular“ free fall situations (without special
equipment or pilot chute) when no canopy is out.
Although the 35 m/s (78 mph) vertical speed re-
quired for an Expert CYPRES to activate had not
been reached under canopy for decades, nowadays
an increasing number of skydivers try and manage
to exceed that speed using low turns and small
canopies.
The number of fatalities involving fully open para-
chutes show that these actions truly enhance the risk
of skydiving dramatically.
Please take all these facts into consideration and use
common sense before making a choice.
For some activities, the Speed CYPRES may not be
suitable.
For instance, already the Expert CYPRES
might not activate during a wing suit jump because the
vertical speed can be too low, and there is even less
chance that a Speed CYPRES will activate. Speed
CYPRES should activate under an open main if the
vertical speed is pushed above 46 m/s near or below
the activation altitude. In case you exceed this vertical
speed, then have your Speed CYPRES switched off.
