Key Functional Parameters Influencing the Cost of Laser Rangefinding Binoculars
① Measuring Distance: This is the key specification of laser rangefinder binoculars, referring to the maximum measurable distance. Their measuring range is generally 400–2000 meters, which represents the straight-line distance from the measuring position to the target. Another important specification is horizontal distance (these two concepts must not be confused). The rated measuring distance of laser rangefinder binoculars is theoretical and subject to weather conditions. Therefore, when selecting a rangefinder, it is recommended to choose a model with a maximum measuring distance approximately 20% longer than your actual requirement. Measuring distance is the most critical factor affecting the price of telescopic laser rangefinders.
② Height Measurement Capability: The ability to measure horizontal height. Many rangefinders support this function and may also be called hypsometers. Another definition of height measurement refers to measuring the vertical height difference of the target (height difference measurement). These two concepts must not be confused. Currently, brands offering height measurement include Trueyard and Orfa. The Nikon 1000AS can measure height but cannot measure angles. All Bushnell models lack height measurement capability. Models with height measurement function are relatively more expensive than those without this feature.
③ Angle Measurement Capability: The ability to measure angles. Many rangefinders are equipped with this function and can also be referred to as goniometers. Many Trueyard and Orfa models support angle measurement, while none of Nikon's models have this feature. Some Bushnell models are capable of angle measurement. Angle measurement capability is another major factor influencing the price of telescopic laser rangefinders.
④ Target Absolute Height Measurement (Height Difference Measurement): Different from the aforementioned height measurement, this function calculates the actual height of the target itself and is only available on premium rangefinders. At present, only the Trueyard SP1500H is equipped with this advanced feature. Orfa released new models with this function in Germany in May 2012. Bushnell and Nikon have no such available models.
