Altimeter Barometer Thermometer Weather Tool

Compact 9 × 5 × 2 cm unit weighing approximately 65 g (battery not included). Manufactured from hard-wearing ABS plastic in black-grey. Delivers five core environmental readings: instantaneous barometric pressure, absolute altitude (referenced to mean sea level), relative altitude (user-definable zero point), ambient temperature, and a 12–24 hour weather forecast valid within 30–50 km. Barometer is default on startup; [ALTI] toggles to altitude view. Absolute altitude appears immediately. To switch to relative mode: hold [ALTI] until '0M' appears at screen base, then move — net elevation change displays dynamically. Hold [ALTI] again to exit. Forecast updates passively as pressure evolves; no manual refresh needed. All operational parameters — time (12/24 hr), date (Y/M/D), temperature (°C/°F), pressure (hPa/inHg/mmHg), altitude (m/ft) — are adjusted via the SET menu. Each field highlights sequentially; value adjustment uses only [ALTI] (up) and [-] (down). Final exit is automatic after 10 seconds idle or manual via [HISTORY]. Supplied with English manual; CR2032 battery sold separately.
