Introduction

The Tracker 670 is a compact easy to use laser rangefinder designed for a range of
outdoor activities such as golf, hunting, site surveying, walking and rambling. A
compact 6x magnification monocular, the Tracker 670 provides accurate
measurements of targets up to a range of 600 metres. It can also simultaneously
measure the angular distance to and height of an individual target being observed.

Quick Start Guide

For a detailed guide see page 4.

Use the power button marked ‘O’ to activate the unit. When powered on the device
is set to Range-Finding Mode. To toggle between Range and Range & Angle
measurement, briefly press the ‘MODE’ button. The LCD will show either Range or
Range & Angle.

In Range mode, pressing the power button briefly will capture the distance to the
target in the centre of the crosshair display. The maximum range that can be
measured depends on the size and properties of the target object. Large, bright
objects can be measured more accurately and at a greater distance than small, dark
objects. To change the unit of measure, press and hold the ‘MODE’ button for 2
seconds. The display will toggle between ‘M’ (metres) and ‘Y’ (yards).

In Range & Angle mode, press the power button once the target object is in the
centre of the crosshairs. The LCD will display the shortest distance to the target, as
well as the horizontal distance, the angle of inclination plus the approximate height
of the target. To change the unit of measure, press and hold the ‘MODE’ button for
2 seconds. The display will toggle between ‘M’ (metres) and ‘Y’ (yards).

The unit will power off automatically if not used for 20 seconds.

Operating Modes
The Tracker 670 has two operating buttons marked ‘O’ and ‘MODE’. Depending on
the status of the device, these buttons will power on the device, set the operating
modes and capture the measurement data.

Focusing
The eyepiece is used to view the internal LCD screen and to observe the target. The
eyepiece also acts as a focusing ring and has a quarter turn of travel (+/- 5 dioptre
adjustment). Adjust the focus until both the LCD screen and the target are in focus.
Note: If the LCD screen is out of focus but the target is in focus, the target distance
is too close to be measured.

Laser
Using a Class 1M eye-safe laser beam, the Tracker 670 emits short bursts of laser
energy from the emitting lens. These are then reflected from the target and returned
to the measuring lens. The device should be held so that the emitting lens is above
the measuring lens. Note: the laser beam is not visible to the naked eye.

Battery
The battery compartment can be accessed by unscrewing the compartment lid. It
houses a 3V CR2 non-rechargeable lithium battery. The battery should provide
1500-2000 measurements under normal operating conditions. Alternating between
range and range/angle scanning modes will reduce battery life more quickly.
