MANUAL

REV. 02, SEPTEMBER 2022
VISO II+ is a trademark of LB Altimeters, Denmark.
LB Altimeters 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.

3
FAILURE TO FOLLOW ALL WARNINGS, INSTRUCTIONS, AND REQUIRED
PROCEDURES MAY RESULT IN 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 ying or sky surng. Chest mount altimeters are more
vulnerable to this problem. If you are in doubt about how this limitation a󰀨ects your
skydiving, consult a licensed instructor.
DO NOT use this equipment unless you are in, or have passed an approved skydiving
course.
Use the VISO II+™ at your own risk.

freefall and under canopy.
(When preset, press to view the current date).

15
Altimeter Displays
In Altimeter mode the LCD may show 3 di󰀨erent displays, depending on what altitude
value is shown.
If the altitude is below 1000 the altitude is displayed as nor-
mal. Altitude resolution is in 10 feet (5 meter) increments.
If the altitude is 1000-9999, the altitude is displayed as tens of
feet or meter. Altitude resolution is in 10 feet
(10 meter) increments

16
If the altitude is 10000 or higher, the altitude is displayed as
hundreds of feet or meter. Altitude resolution is in 100 feet
(100 meter) increments.
Speedometer Mode
When the VISO II+™ is set to Speedometer mode, the SPEED,
“Feet/Meter”, “Mph/Kmh” and “TAS/SAS” icons are ON.
The VISO II+™ will display the climb rate/speed during climb,
in freefall and under canopy.
The date/time information switches OFF during freefall and
under canopy.

Speed resolution is in 1 Mph (1 Kmh) increments.
Important Notice about Speed Recordings
Experience has shown that when mounting the VISO II+™ on the hand or belly,
di󰀨erent air pressures induced by hand or body movements may result in incorrect
recordings of speeds.
