Radiant SafeAlt Portable Altimeter / VSI Combo - Black Case

The Radiant SafeAlt is a self-contained portable instrument combining an altimeter, vertical speed indicator (VSI), temperature display and continuously calculated density altitude in a black case.

Designed for clear at-a-glance altitude awareness, SafeAlt combines a classic dual-needle analogue altimeter display with a digital altitude readout. Vertical speed is shown on both an analogue gauge and a dedicated digital display, while temperature, density altitude, Kollsman setting and battery voltage remain visible on screen.
