Everlasting Laser Rangefinder: multifunctional tools designed to satisfy multiple measurement needs

As you mentioned, an "everlasting" laser distance meter refers to one with an extended battery life or power source enabling continuous or extended operation without frequently charging batteries or replacing batteries. Unfortunately, such products don't exist on the market yet but I can provide information regarding various laser distance meters with various functions to meet different measurement requirements.

Laser distance meters, commonly referred to as rangefinders or tape measures, use laser technology to accurately measure distance. Here are some features and functions commonly seen in these multifunctional tools that make them the go-to measurement solution:

Distance Measurement: A laser distance meter's main purpose is to accurately and precisely determine distances. These devices utilize laser beam technology to assess the gap between themselves and an object of interest, giving quick measurements in seconds that provide precise results. Their measurement range varies according to each model available on the market.

Area and Volume Calculation: Many laser distance meters come equipped with built-in functions to calculate area and volume based on distance measurements. By taking length, width, and height measurements from an object or space being measured, a device such as this one can quickly calculate an object's area or volume without manual calculations being needed - saving both time and effort!

Pythagorean Theorem Functions: Laser distance meters often incorporate features that take advantage of Pythagorean theory in order to measure distance indirectly, making measurements possible in inaccessible or difficult-to-access places, like measuring building height by taking measures from its base and top angles. This allows accurate distance readings even on complex buildings such as tall ones like skyscrapers.

Continuous Measurement: Some laser distance meters offer continuous measurement modes that enable real-time tracking of distances. This feature can be particularly helpful when measuring moving objects or irregular shapes quickly in succession or taking multiple measurements quickly in quick succession.

Addition and Subtraction: Many laser distance meters come equipped with functions to perform basic mathematical operations like addition and subtraction, making this feature particularly helpful when trying to calculate cumulative distances or offsets.

Bluetooth Connection: Some advanced laser distance meters offer Bluetooth connectivity for wireless data transfer between smartphones, tablets or other compatible devices and the laser distance meter itself - providing seamless storage, analysis and sharing using apps or software designed specifically to handle these types of needs.

Inclination Measurement: Certain laser distance meters come equipped with built-in inclinometers or tilt sensors capable of accurately gauging angles and slopes - an invaluable feature used in construction, surveying, and landscaping applications.

Memory and Data Storage Capability: Laser distance meters often feature internal memory or external storage capabilities for recording measurement data for later analysis or reference, ensuring measurements can be recorded efficiently and arranged effectively.

Before selecting a laser distance meter, take into account factors like measurement range, accuracy requirements, available functions, display readability and durability as well as any specific features tailored towards your intended applications.
