Built-in jump data
The ARES II stores date, time, exit altitude, opening altitude, freefall time and maximum/average speed for up to 200 jumps.
Designed around visibility
Technical where it counts. Simple where it matters.
A focused visual instrument: fast to read, built to travel, and configured around a clear digital altitude display rather than a distracting screen full of extras.
Automatic calibration
After it is switched on, the ARES II continuously calibrates to the field elevation and accounts for weather-related pressure changes.
Built for the jump environment
Precision-machined aircraft aluminium, a 2 mm hardened-glass lens, and a waterproof rating of 3 ft for 2 hours.
Useful jump information
Choose feet/metres and mph/km/h. Review daily count, total jumps, exit/opening altitude, freefall time and speed.
More than a number on the screen
Review the jump after you land.
The ARES II keeps the data that matters close at hand without turning the visual altimeter into a phone app. It is a practical record of what happened in freefall and under canopy.

Before you jump
Know what is included — and what to check.
The ARES II comes with a Velcro hand mount and LB Altimeter Tool. If you prefer a wrist-mounted position, the optional elastic mount above is available in multiple color and size combinations.
Read the official manual before use. A visual altimeter may fail or show erroneous readings; maintain visual altitude awareness, switch the ARES II on before boarding, and follow LB’s published instructions.
What is included with the ARES II?
The ARES II digital altimeter, a Velcro hand mount and LB Altimeter Tool. The elastic wrist mount is optional and sold separately.
What does the logbook record?
Up to 200 records can include date/time, exit altitude, opening altitude, freefall time and maximum/average speed.
What batteries does it use?
The current LB manual specifies two Renata CR2325 batteries. Settings and logbook data are retained in non-volatile memory after battery changes, though the time may need resetting.
Is it waterproof?
LB rates the ARES II waterproof to a depth of 3 ft for 2 hours. The battery cover, seal and correct screw torque are important before any water jump; consult the official manual for maintenance requirements.
