Developed and built by skydivers, for skydivers

Highlights:

Always On feature which automatically detects Ground, Airplane & Jump modes and thus removes the need to manually activate the altimeter before each flight
Rechargeable via standard micro-USB cable (included), though a battery load should last for quite a while between charges due to reduce power consumption
Compact size 54×36×12 mm (2.12×1.4×0.5 in) and weight 24 g (0.85 oz)
Both visual & audible indication (digital display & acoustic alarms), which means it can be used in both hand-mounted and helmet-mounted configurations
Supports 5 jump profiles with editable names (default: AFF, Belly, Canopy Control, Tandem & Vertical Formation) for the Freefall & Canopy modes with 3 altitude alarms each
Selectable language (En, De, Fr, Sp) and measurement units (metric, imperial), it has rotate-able screen orientation (for equipping on right-hand or left-hand), light or dark theme, and various other configuration settings
Auto-lock (manual-unlock) feature, which can prevent accidental manipulation of the device settings (via buttons) during Flight & Jump modes
Collect up to 1000 jump logs which may be retrieved later via PC software available on the SUPPORT page
(Note: this software may also be used to update the device firmware)
