Do not distance the target within 5m to avoid damaging the instrument!
Do not disassemble the corresponding parts of the product, non-standard operation will cause damage to the product and will invalidate the warranty!
Please keep the optical glass surface (laser, telescope objective, eyepiece window) clean!
Do not measure the distance through glass or other translucent materials, so as not to cause the ranging error to become larger!
Extreme weather conditions such as rain, snow, fog, haze, and dust will affect the ranging performance!
If you do not use the product for a long time, please remove the batteries!

Product overview

Handheld laser rangefinder is developed based on the 1535nm erbium glass laser independently developed by our company, which

belongs to Class 1 eye-safe products.

The main functions are: single-point ranging, two-point ranging, angle measurement, height measurement, distance gating, target positioning, ballistic calculation, real-time display of measurement information in the eyepiece, power indication, data transmission and other functions. It is mainly used for one-handed holding, and can be used with a tripod for long-distance targets.

Small and lightweight, it fits easily in your pocket.

Directions for use

1. Ranging & Angle

Press "↑" to Power on,default measuring range and angle mode.

Aim for the target,press "↑" to complete measurement.

Long press "↑" to continuous ranging at ranging and angle mode,release to stop. * Angles are not displayed when continuous ranging or measuring multiple targets.Up to measuring 3 targets in multi-target.
