Telescopic laser rangefinder main functional factors affecting price
1. Measuring distance:
This is the main indicator of the laser rangefinder telescope, refers to the telescope can measure the farthest how much, telescope measurement distance is generally 400-2000 metres, this distance refers to the measurement of the position to the measurement of the target of the straight line distance. There is an important indicator behind, is the horizontal distance (these two concepts must not be confused). The measurement distance of the laser rangefinder telescope is generally a theoretical measurement distance, which will be affected by the weather. So when you choose a rangefinder, in principle, you should choose a laser rangefinder telescope that is about 20% farther away than the farthest measuring distance you actually require. Measuring distance is the most important factor affecting the price of telescope laser rangefinder.
2. Whether it can measure height:
Can measure the horizontal height, many rangefinders with this function, so this rangefinder can also be called altimeter. Another concept of altimetry is to measure the absolute height of the target (altimetry), the two concepts must not be confused. Currently on the market can measure the height of the brand is mainly Touyad and Olfa, Nikon 1000AS can also measure height, but can not measure the angle. All the models of Dr. Can can not measure the height. The price of models that can measure height will be relatively more expensive than those without this feature.
3. Can measure angle:
Many rangefinders come with this feature, so they can also be called goniometers. Many models from Toujad and Olfa have this feature, while all Nikon models are not able to measure angles. Some of the models from Dr Can can measure the angle. The ability to measure angles is another major factor that affects the price of telescopic laser rangefinders.
4. Can measure the target height (altimetry):
With the previous concept of height measurement is not the same, is to measure the height of the target itself, which is a rangefinder only have the function. Currently, only Toujad's SP1500H has this advanced feature. But Olfa's new product released in Germany in May 2012 has a rangefinder with such a feature. Neither Dr Can nor Nikon has such a model.
5. Can measure horizontal distance:
The measuring distance mentioned earlier refers to the straight line distance from the measuring position to the measuring target, while the horizontal distance refers to the horizontal distance from the measuring position to the measuring target. These two distances are not the same. This is ** rangefinder only have the function.
6. Can continuous ranging:
Continuous distance measurement is very useful in many cases, so this function is also very important.
7. Continuous angle measurement:
Continuous goniometry is a feature found on some ** laser rangefinder scopes. Continuous goniometry means that there is no need to trigger the infrared emitting lamp to measure the angle continuously. At present, only Toujad SP1500H has this function.
