8-in-1 Handheld Digital Altimeter Barometer Compass Weather Forecast Thermometer 90x50x20mm ABS Portable Mountaineering Fishing Outdoor Electronic Altimeter with Detachable String and Backlight
8-in-1 Handheld Digital Altimeter with Barometer Compass and Thermometer

This 8-in-1 handheld electronic altimeter is a compact outdoor instrument that brings together a digital altimeter, digital barometer, digital compass, weather forecast, time, calendar, thermometer and backlight. It is designed around an electronic orientation sensor and an air pressure input sensor, allowing it to display altitude, bearing and related readings for activities such as mountaineering and fishing. The detachable string makes it easy to carry, and the backlight can be activated with a button press when lighting is limited. Its ABS housing measures 90x50x20mm, so it fits neatly in the hand. Altitude readings cover -700 to 9000 metres, or -2300 to 29500 feet, and the device can store up to 256 historical records. The compass shows bearing in degrees and base points, the thermometer reads in °C or °F, and the clock can be set to 12-hour or 24-hour format.
Features and Construction

The device is built for handheld outdoor use, combining multiple electronic instruments in one body. Its functions are supported by the electronic orientation sensor and the air pressure input sensor described in the source. The ABS housing gives the unit a defined shape without unnecessary added material. This section outlines the material and size details that are known from the source text.
Material and Build
The housing is made from ABS, a plastic material that forms the outer shell of the 90x50x20mm body. The source states that the device uses an electronic orientation sensor and an air pressure input sensor. These components support the compass and altitude functions. No further performance claims are made beyond the stated functions and specifications. The detachable string is included for carrying, and the backlight is activated by pressing a button. The unit is described as a handheld device for outdoor use.
Size and Practical Fit
With dimensions of 90x50x20mm, the altimeter is small enough to hold in one hand and to carry with the detachable string. The compact size suits activities such as mountaineering and fishing where a pocket-sized instrument may be preferred. The source does not provide weight or additional size information, so only the stated 90x50x20mm measurement is listed. The ABS body encloses the electronic components and the display. The size supports handheld operation when pressing the backlight button or viewing readings.
Uses and Placement

This instrument is intended for outdoor scenarios where altitude, bearing, weather tendency, time and temperature may be useful. It can be used during mountaineering or fishing, and the detachable string allows it to be kept close at hand. The source does not specify waterproof ratings or operating temperature limits, so those details are not claimed. This section describes practical uses that are directly supported by the listed functions.
Event or Professional Use
For mountaineering and fishing, the device offers altitude, compass bearing, barometric pressure and weather forecast functions. It can record up to 256 historical records, which may be useful for tracking changes over time. The compass displays bearing in degrees and base points, and the thermometer shows °C or °F. The backlight supports viewing when a button is pressed. These features are drawn from the source and are suited to outdoor electronic altimeter use.
Everyday Home Use
Outside dedicated outdoor activities, the device can also serve as a clock, calendar and thermometer. The clock can be set to 12-hour or 24-hour format, and the thermometer reads in °C or °F. The backlight helps when checking the display in low light. Because the source does not list indoor-specific features, these uses rely only on the stated time, calendar and temperature functions. The ABS body and 90x50x20mm size allow it to be stored or carried easily.
Benefits and Buying Value

The main practical value comes from combining eight functions in one handheld unit, reducing the need to carry separate instruments for altitude, bearing, time and temperature. The 256 historical records and the stated altitude range are concrete capabilities from the source. The detachable string and backlight add convenience. This section focuses on reuse and practical ownership without making unsupported claims about durability or pricing.
Reuse and Low Maintenance
The device is designed for repeated handheld use, with a detachable string that can be reattached as needed. The ABS housing can be wiped clean with a soft dry cloth if required, though the source does not provide specific care instructions. The electronic sensors and display are housed within the 90x50x20mm body. No battery type, lifespan or waterproof specification is stated, so those details are not included. Up to 256 historical records can be stored and reviewed.
Why Choose This Product
Choose this 8-in-1 altimeter if you need a single handheld device that covers altitude from -700 to 9000 metres, compass bearing, weather forecast, time, calendar and thermometer functions. The 90x50x20mm ABS body and detachable string make it portable for mountaineering and fishing. The backlight supports button-press illumination. The source lists colour options and set contents, but does not provide price or performance comparisons, so the decision rests on the stated functions and specifications.
