About the purchase of laser rangefinder

2. Handheld laser rangefinders are divided into two types: indoor and outdoor. The difference is that the indoor type of handheld laser rangefinder measures within 60-100 meters. Because it has no built-in magnifying sight, it can only be used indoors (the sunlight outdoors is strong and the laser point smaller than a cigarette butt cannot be seen). The outdoor type has a range of 200 meters (the instrument has a built-in telescope aiming amplifier and does not require a reflector when used outdoors in the sun within a range of 70 meters. If you want to use it outdoors in the sun with a range exceeding 70 meters, please use it in combination with a reflector).

3. Brands of indoor handheld laser rangefinders include

A. LDM100 model produced by Huashengchang Company with a range of 50 meters.
B. PREXISO produced by Swiss Leica factory with a range of 40 meters
. C. AGTETEC of France with a range of 60 meters
. D. Leica A2 of Switzerland with a range of 60 meters.
E. Hilti PD4 of Germany with a range of 70 meters.
F. Leica D3A of Switzerland with a range of 100 meters.
G. Hilti PD40 of Germany with a range of 200 meters.

4. Brands of outdoor handheld laser rangefinders include

A. Swiss Leica rangefinder D5 measuring distance at 200 meters

B. The difference between the German Hilti rangefinder PD42 and the 200-meter rangefinder is:

1. A5 is a built-in 2x magnification sighting telescope, PD42 is a 4x magnification sighting telescope.

2. The measurement accuracy of A5 is 1.5 mm, and the measurement accuracy of PD42 is 1 mm.

3. D5 cannot be used for diagonal measurement. PD42 can pull out a thin measuring strip on the back of the instrument to measure the diagonal of the corner.

4. In terms of size, PD42 is smaller than A5 and has a plastic key to lock the battery, making measurement more convenient and more upscale.

5. PD42 is equipped with a reflector, A5 is optional.

6. PD42 has complete certificates, and D5 identification certificate needs to be purchased. The similarities are that the measuring range is 200 meters, both are equipped with telescope sights for outdoor measurement, and there are also supporting facilities and warranty cards.

5. Swiss Leica A6 can realize unlimited Bluetooth and connect to computer serial port to upload data. Swiss Leica A8 can be mainly used for angle measurement.

6. A laser rangefinder with a range of more than 200 meters is called a laser rangefinder telescope.
