Getting the most out of your new laser rangefinder

Introduction

Congratulations! You have just purchased one of the most affordable, quality laser

rangefinders on the market today. Your LR1500-SLOPE rangefinder was manufactured

by a leading, photo-optics company specializing in precision laser rangefinders and

binoculars. We are certain that you’ll be happy with your purchase and enjoy years of

solid performance.

To ensure you get the most out of your rangefinder, we have written this short user

guide to supplement the manufacturer’s manual. Please read this guide carefully before

you start using your LR1500-SLOPE laser rangefinder.

How the LR1500-SLOPE works

LR1500-SLOPE is a precision-made, 8x30mm monocular that incorporates a state-of-

the-art laser rangefinder. The rangefinder sends out a series of infrared energy pulses

that are reflected off the desired target. Precision-made optics and built-in computer

circuits are used to calculate the distance by precisely measuring the time taken for

each pulse to return. This unit is capable of measuring distances to a reflective target up

to 1500 yards (1400 meters) away.

Understanding the factors that influence distance readings

Manufacturers specify maximum distance ranges only as a reference for the user.

Actual maximum distances measured will vary depending on a number of factors.

Factors such as surface texture, size, color, shape and reflectivity of the target will all

affect the ranging performance of the instrument. In general, large, bright-colored

objects are easier to range than small, dark-colored ones.

Weather and light conditions may also affect ranging performance. Users are often

surprised to find out that bright, sunny conditions (particularly when ranging towards the

sun) can cause decreased performance. This is because infrared energy produced by

the sun can interfere with the infrared energy pulses produced by the rangefinder.

A clear line-of-sight to the target is also a critical determinant affecting ranging

performance. For example, overhanging branches in the foreground can reflect the laser

intended for the target further away and provide shorter distance readings. Conversely,

shrubs and trees in the background of a small target may reflect more of the laser

causing inaccurate readings. These issues are common to all laser rangefinders

(including Bushnell and Nikon brands).

Your laser rangefinder comes with 5 special – STANDARD, SCAN, BEELINE, HIGH, and

ANGLE – measurement modes. “STANDARD” mode is the default mode your rangefinder

will be set to and will the mode you will use under most conditions. SCAN mode allows

the user to “scan” the target and surrounding area to get continuous distance

measurements. BEELINE, HIGH and ANGLE modes provide angle compensated True

Horizontal Distance, the Height of the object and the Angle to the horizontal,

respectively.

GETTING STARTED

Getting the LR1500-SLOPE set up for use will be a breeze if you follow these steps:

A) Installing Batteries

1) Remove the LR1500-SLOPE from the box and unpack contents

2) Open the battery compartment by turning the battery cap counter-clockwise.
