Digital Altimeter with Compass and Barometer — durable, compact navigation and weather tool for outdoor use Key benefits and why you need it Durable protection: the ABS plastic shell resists impacts and stands up to rough handling and harsh outdoor environments so the instrument continues to work when you need it. Accurate environmental readings: built-in altimeter, barometer and temperature sensor provide the data you need to plan routes, monitor weather changes, and make safer decisions on the trail. Easy to carry: compact, lightweight design fits in a pocket, pack, or small kit so you always have essential navigation and weather information without added bulk. Improved situational awareness: the integrated compass plus altitude, air pressure and temperature measurements help you navigate, anticipate weather shifts, and validate map or GPS data. How it solves common problems Stop guessing your elevation: the altimeter gives reliable altitude readings so you can track gain/loss and follow elevation-based route plans. Detect weather trends early: the barometer (300–1100 mbar) helps identify pressure changes that often precede storms or clearing weather. Know temperature limits: the temperature gauge (-10 °C to 60 °C) helps you confirm conditions for appropriate clothing and equipment. Maintain direction without electronics: the built-in compass provides a simple, dependable orientation aid when electronic devices fail or battery power is limited. Important specifications (consistent with product details) Housing material: ABS shell for strong impact resistance and durability Functions: digital altimeter, barometer, temperature gauge, and integrated compass Temperature range: -10 °C to 60 °C Altimeter range: -700 m to 9000 m Barometer range: 300 to 1100 mbar Size/weight: compact and lightweight (designed for easy carry) Practical applications — specific scenarios Mountain hiking and mountaineering: monitor altitude changes on long ascents, check barometric trends for incoming weather, and use the compass to confirm route headings at trail junctions or in low visibility. Multi-day backpacking and navigation: keep a small, rugged instrument in your pack to verify elevation profiles, anticipate weather shifts, and maintain bearings when GPS devices lose signal or battery. Outdoor work and rescue planning: useful for field teams who need reliable altitude, pressure and temperature readings to coordinate logistics, assess conditions, and support decision making in remote sites. What makes it stand out Robust ABS construction for extended field use Combined navigation and environmental sensors in one compact device Clear, practical measurement ranges suitable for most outdoor activities up to high altitudes Compact, durable, and practical — this digital altimeter with compass and barometer gives you essential, field-ready information to navigate and make safer outdoor decisions.
